The Syma S107 Review
Syma S107 - My Review
Welcome to My Madness on Indoor RC Helicopters.Especially Syma Helicopters
I started this hobby a few years ago, because I have always been fascinated in aviation. I found it was a fairly cheap hobby to get started in. I was not really wanting to build a model at that time, but to be able to buy a RC heli completed and ready to fly-Welcome the electric RC helicopter, especially the mini helicopters that you can fly at home. Syma helicopters are just the best mini rc heli to start out with.
After buying around 11 RC helicopters, smashing the hell out of them and rebuilding them time again with spare parts, I came across the SYMA S107 also known as Syma S107G.
My Syma S107 Review:
The Syma S107 is a coaxial helicopter, having two main rotors stacked on top of each other.
The picture below shows how these two rotors spin in the opposite direction of each other and thereby cancel out the reactive torque that is produced by each.
Having two rotors also produces a significant gyroscopic effect that further stabilizes the helicopter. This makes this style of helicopter extremely stable and great for a beginner starting in RC Helicopter flying.
The Syma 3 channel S107 mini helicopter comes in a variety of colors, including blue, red, and yellow. However due to being so popular not always able to get the color one wants. I now have a Syma107 in every color-(told you am heli crazy)
Inside the box you get the helicopter itself, sturdy and well made, a infra red remote control with 3 channels built in , so that more than one toy won’t interfere with the other.
Also included is the proprietary USB cable that allows the RC helicopter to be recharged in just around 30 mins or less, when you plug it into a PC. Tip: When usb yellow charge wire pluged into PC will show a red light, check the brightness. When you plug Syma heli to charge light goes out. Fully charged when red light comes up bright as before, faint flickering red light not fully charged so wait. Always wait 10-15 mins between flying before charging to let battery cool down, helps for longer battery life-hard to wait I know!
You can also charge it direct from the remote. The S107 has a built in rechargeable battery. The remote control itself takes 6 AA batteries, so you may need to buy some when giving the Syma as a present to someone else.
It is a Serious Toy for Adults and Kids.
The latest 2010 version by the famous SYMA Toy Company, equipped with a 4-in-1 infra-red receiver (Gyro, ESC, Mixer, Receiver). This palm size S107 Toy Helicopter (18.5cm long) comes with Aluminum Frame and a Great detail canopy, it doesn't look like a toy, but a very serious Helicopter. It is able to move in 3 Direction based on the 3 Channels, anyone can hover it easily. Since it is made with Aluminum Frame, very light weight and almost indestructible in any crash, perfect for very first time beginners. This helicopter is designed for anyone over 8 years old, flight time is around 5-8 minutes after 20-35 minutes charging by USB or Remote. It can fly in 6 directions. They are:
- Rotate Clockwsie / Anti-Clockwise
- Move Forward / Backward
- Move Up / Down
Flexible blades & balance bar-less damage on crashing.

Problems I Found With The Syma S107:
I have to say there were not many-However there are some fakes out there-things to look for is--
1: Correct to have a square type charge outlet on the Syma107 not round-from some forums seems to have a soldering problem. Some fake photos below of rotor fakes.
Fake
Fake Syma 107 Info As Below
The main blade holder of fake S107 is made of metal, the genuine one is plastic in pure black color. The main blade of the genuine Syma S107 have a few lines about the warning. However, the fake one only have the word “WARNING"- Something to check. I do own a clone-It still fly's well: Clones are different to fakes: READ POST
2: Out of the box the SymaS107 should fly with only minor trim alteration which is in the middle of your remote- start to throttle up-when flying and turning to left or right trim using the remote-should be one notch-If the SymaS107 spins like crazy after adjusting trim, something is wrong, do not take it apart -send it back-Hence I only buy from reputable dealers, like Amazon
3: Can be a problem binding the Syma to your remote - is easy to fix tho-Try this- Switch on the transmitter and place next to the S107. Switch on the S107 and stand in front of the transmitter till the flashing green light goes solid. You should now be ready to fly.
4: Because this is a stable heli, your crash rate should be low until you get cocky- good thing is parts are cheap to replace. (Spare Parts Syma S107)
5: Do not fly near digital TV or charge near one- watch out for very bright room lights,to me this is a indoor heli only and can not stand a breeze out side or a bright sunny day as the remote is infra red- If you want a heli to fly outside the SymaS107 in my opinion is not designed to do this - Having said that I do fly mine at night with no breeze on occasions. When flying inside try not to get to close to your ceiling as air turbulence will effect it and lose control-this happens with any indoor helicopter.Turn off fans and do not fly near air conditioners-Pretty obvious really.
6: It takes 20-35 minutes to charge the fitted battery- this can be a pain as you can not wait to fly this little bird more and more- To charge by remote takes longer and soon burns out your AA remote batteries - Use the USB supplied- hell quicker to charge.
7: Another tip: After a flight with any fixed battery helicopter a good idea is to let the battery cool down before you recharge-Reason being it will preserve the battery longer as they do get warm -That is why I have a few Syma helicopters being charged by my USB- So look for good deals to buy two-Only my view.
8: One small issue I had was flying backwards-The heli looses altitude and gets a little bogged down, it does go backwards but real slow. If you are looking for big flying speed backwards this heli might not be for you. I never fly backwards can not see the point prefer forward and spins. There is a modification on tail rotor. Did try it and yes makes a difference but burns up battery power if flying backwards all the time-Syma S107 left as it is to me just great. Want more from your heli buy a bigger more expensive one.
The Great Points:
Where to start: This is without doubt the best little mother heli I have owned-it is so stable. As soon as you stop going forward or back, she just hovers awaiting your next move-problem I found was I just got so cocky flying the bird that I started to dive bomb my dog who eventually won out by jumping from a chair and grabbing it in its mouth -Pain for both-The dog won, hence I bought two more Syma S107.
But from my heart this great helicopter at it's price that you should be able to buy for around $20- $25 shipped is the best value in life, and will give kids from 8 to a old fart like me at 60yrs old the greatest fun ever- I get excited every time this bird is charged and ready to fly- As I have 6 of them now my poor old computer is constantly charging my Syma 107. I am "Excited"
To be really honest I am amazed at the quality of the Syma S 107 for the price. I would have liked to see a better remote not being infra red and a bit more robust, however it does the job, and again for the price one can not really complain. Have seen replacement remotes for $11 should you break yours-not good idea to drop it on concrete floor!
I am working on some modifications with battery. I have one stripped to the bones at the moment as like a kid want to see how it works so well-you need a small screw driver set for this.
Screwdriver Set What I did was rub a magnet on the required screw driver to magnetize it so able to hold the very small screws to the screw driver, helps a lot.
Would I Buy The 107G Syma
100% Yes from me!
WHERE TO BUY THE SYMA S107 WITH SAFETY
Here are my trusted links below that I have personally bought from- I am always trying to find the best value, but also genuine Syma's sold with trust and back up to return if defective in anyway.
For Syma Helicopters:
I have purchased many RC Helicopters and Drones from Amazon - Yes good experience.. Just search on site for Syma, heaps to view.
I have posted a Syma S107 Spare parts page
All the Syma Helicopters That I have bought from Amazon have not been fakes also any problems Amazon have a return policy.
Yes you can buy cheap Syma S107 spare parts- View Here
I do not recommend buying from Ebay as there are too many fakes there, I found out myself buying 4 all fakes and never flew out of the box.
The Syma S107 is a fantastic helicopter: I have a forum now set up- Feel free to view and post on Syma helis and Syma Quadcopters, also posts for other RC helicopters.

Some good Syma videos: Main Video Page
Something is wrong with my heli. It takes off slowly (even on a full charge). When it gets into a stable hover, it flys fine until I release the trottle a tiny bit. It sort of shudders a bit and crashes. Even if I pull on the trottle, it still won’t come up. I’m pretty sure it’s something with the lower set of blades. They feel like they aren’t as loose as they should be, though I can’t spot anything stuck in it. (If you want, I could give you a link to a video.)
Have you joined forum for free? This video might help-Click
Please post a link to the video.
I’m pretty sure I can see a hair stuck between the shaft and the lower rotor head. If I could figure out how to take it off without breaking something, I think I may be able to fix it.
(oh, and I’ll post a video once I put it back together. It’s sitting in pieces on my desk).
Oh, and my problem is different then the one shown in the video.
Somehow, after disassembling my heli, I managed to fix it. Now I have another problem.
40 min, charge time
3 min. fly time (until my heli wouldn’t get more then an inch off the ground)
3.3 min. till I had ran off the battery completely.
I’ve had my (genuine) S107 for less then a month and I’ve crashed it numerous times. As I already mentioned, it’s been taken apart (all the screws I could find I unscrewed) and put back together. The only mod I’ve done is a tail rotor replacement (I used the rear rotor off an old air hogs– it made my syma faster). Any ideas? (Oh, and I joined the forums though they’re giving me trouble as well. Whenever I try to log in, it just refreshes the page. Maybe it’s a problem with my tablet. I don’t know.)
Hi,
I have just purchased one and after a couple of flights the bottom rotor blade has stopped working, the top one is spinning fine, any thoughts much appreciated!
Mike
Its ok! I ve managed to fix it, a tiny little cog had slipped down so wasn’t connecting to the main one that drives the bottom rotor.
Great to hear-http://syma107.com/forum/frequent-syma-107-problems-and-how-to-fix/the-gearbox-in-detail/
I have a problem with my S107.When i bought it it worked perfect.I tries to flay it at home but the propellers just wound¨t spin.I charged it,I bought new battery,but the propellers didn’t spin.I need help fast!!
What battery did you replace with and how did you connect wires-soldering? Also check main shaft-Video Here
Hi,
I want to buy a GENUINE helicopter SYMA S107G, but it is very hard to know what is genuine and what is fake.
My question is … which of these sites is the official website of SYMA?? (or is it both?)
1- http://www.symahelicopters.com/
2- http://www.symatoys.com/index.html
Thanks,
Energy
Not sure about the sites but I got all of mine through Amazon. I look for the store Xheli and try to get most of mine though there. I did get 3 fakes through a different store on amazon but sent them back without a problem. I’ve order over 30 in the month of November. I think Xheli is about the best.
I got 2- S107’s for Christmas. They were bought on thinkrc.com. Everything seems to match with them being genuine Syma’s, and they fly great! Has anyone else bought from them?
Are there any specific sellers on Amazon to only buy them from?
I have a 2 week old yellow S107 gyro. It flew great for the first few times. It has had some minor crashes, nothing bad. But now it will not hover. I get it less than a foot off the ground and then it goes crazy, spinny circles, like the drunk driving and then goes down. I have replacement parts, nothing is loose, nothing is broken. I have checked everything. Any suggestions?? What can I do to fix it?
Supernova on the forum has made a great video which could be your problem http://youtu.be/XR9IMkmZvCw main shaft repair
I have my first ever RC and it started that after several indoor crashes. The pins of the top rotor blade mount were broken.
Lookup a photo for part number s107-13 and look for the two stubs below the screws. And/or, remove the connect buckles from between the balance rod and top blade holder. If the holder and blades fall down, the pins (stubs) are broken. You have to buy the upper shaft assembly to get that part but do not have to replace the entire shaft. Hope this helps…
http://syma107.com/forum/frequent-syma-107-problems-and-how-to-fix/ We are working on videos to fix easy flying problems
It finally happened to me! After several hundred crashes, I had a bad crash and broke the pins in the top rotor assembly. With an old long-proven genuine Syma. It only happened because I got distracted and the heli climbed to the roof beams, crashed and landed on a tile counter with power on (modified throttle with no return spring). My guess is that it can only happen in a power-on crash. Thanks to this forum I was able to quickly identify and fix the problem, as I had a parts heli handy.
My son’s S107 survived many crashes, but finally after one from about 10 feet, it will not lift off. There doesn’t appear to be anything broken or loose, but we think it is a little noisier than it was. He thinks the noise is coming from the motor or gear area. The gears seem to be working fine. The blades seem to be spinning fine. We tried charging it longer. It gets maybe an inch or twoo off the ground then crashes. Any ideas?
I am currently having the same problem with my S107. I replaced a blade that had broken, but all else seems to be working find. Just will not lift off very high or for very long.
I’m having the same problem, From what I have read it looks like I charged the Battery to soon after flying it and depleting the charge. The Battery In The S107 learns in the same way a Brand New Cell Phone Will. either you have not let it cool down and charged it enough times it has melted cells and decreased the power output therefor not allowing it to lift but still run 5 min or so. Replace Battery is the only option. To get the Best life. Charge Completely, Run Down Completely and allow a MIN of 15 min before plugging it back in to charge.
Option B: Check gears and screws to make sure all is snug.
I’ve gotten many hours out of my Syma s107 and am pleased the cheap china battery has help up this long. Although it’s been under a month since it was purchased and probably gone through 45-65 charges/flights (up to 11 min) before encountering this issue.
But for the price of this HELI, best on the market for stability, control, and Price. I do suggest just buying a new S107 G so you get the right/left motion control an (3.5 ch.) and then you’ll just have spare parts using your s107.
Correct BATTERY CARE: life & Performance can more than double
i had the same with my 033G.
stripped gears! the rotor spins but due to the stripped gears, wil NOT GENERATE lift…
are there any difference between the s107 and the 2012 s107g that is on amazon?
Just got my third Syma S107g. The other two fly great! However, this yellow one worked good for one minute then had very little lift. When I land and kill power the top roter spins 20+ times until it stops, the problem is the bottom rotor does not freely spin (only one revolution without power). The motor can spin it however it has so much drag/friction somewhere it can not take off. All the gears look good. I can turn the bottom blades by hand, but there is a lot of drag. Can someone tell me what the problem may be. motor? gears? shaft?
thanks,
Jeff
With any coaxial helicopter the top blad has a flybar on top with two little weights on the ends to keep the heli stable, that means that the top rotor will always take alot longer to completly stop spinning than the bottome rotor that has no flybar, this is to do with extra weight only thought 20+ spins sound a bit more than usual! have you lubricated the gears? if so then too much lubrication can cause the heli to not lift off. the other thing to do is see if there is any hair or fluff stuck in the gears or shafts.
HI… just got one from a friend for 44th birthday today 🙂
Noob question:
Notice in unpacking that the rotor blades are not fixed in one position, but are loose, even though the screws holding in place are pretty tight. Is this supposed to be like that or should I be tightening them?
(Def. genuine article btw)
Thanks
Yep thats how they’re supposed to be. Soon as you start to get the rpms up they’ll straighten right out. Nice thing about the way this stuff works is that if you get into trouble, drop power and any items that are smacked will fold the blades back hopefully keeping anything from breaking. Of course if power is kept on all bets are off and things will start to break from multiple smacks.
Hi Can you please put in a review on the Syma s105g, i have one and have flown hard and have had a great time, it seldom gets crashed, I am into methanol airplanes and get a bit tired of having to drive to the airfield everytime I want to fly. this heli is great for just picking up at the end of the day and relaxing in the chair with it buzzing around after pets and landing on tricky places, I am looking to buy a syma s107g now to see if its anything as good as the s105g. I Want to know if the transmitter from the s105 would work with the s107g can you please answer.
Cheers!
Just picked one of these up from all-battery.com for $28 shipped via FedEx. Genuine article and flying right out of the box with a tiny trim adjustment. Very easy to fly and flies much better than the other plastic one my father-in-law bought my daughter for Christmas. That thing takes a while to trim out, and you have to re-trim it after you try to do anything but hover. We have had minimal success trying to get the other one to fly forwards, backwards, or turn. I have had the S107 for about an hour and it is fantastic. Don’t waste you money on any other micro-heli.
hey my syma remote control does not work anymore.. the product is brand new, a few in our office have bought them as well and their controllers work on mine no problem..
any tips on fixing this?
Thanks
try opening up the transmitter through 6 screws in the back (one of them is under the chargers hatch) Once open, try to see if there are any broken wires that are visible, especially the two that connect the circut board to the batteries, then try soldering them up but before you do anything try to return it to the shop as a faulty product, Its for these reasons that buying products from trusted sites such as amazon is very important.
I’ve just got one of these and it’s great fun but I’m having a slight problem (I think?)
When I push the left throttle to ascend as expected the helicopters moves upwards but at the same time slowly moves backwards.
I have played around with the dial on the remote but it doesn’t seem to make a difference.
Any ideas?
It’s a little tail heavy. Try adding a little weight to the nose.
My helicopter was working great at first but now it doesn’t fly forward or backwards. Is it a problem with the connection or something else? What can i do to fix this?
Forward and backward flight is a product of the tail rotor being powered up. First and easiest fix is to make sure that there is no obstruction such as hair, lint wrapped around shaft inhibiting rotation. If no obstructions, hold heli in one hand while giving forward or backward stick. Tail rotor should cycle on in each direction. If that doesn’t work, carefully check the electrical connections to the tail rotor motor. Those are the most obvious and common issues. Good Luck!
Whilst flying my little red beuty it developed a sudden fault. For no reason atall it began to fly in ‘drunken’ circles with became worse when steering. I have not crashed my heli and am seriousl concerned
Mine did that too… take OFF one of the connector buckles from the top rotor. Flying with one buckle will solve the problem. Of note, in my instruction manual the helicopter is depicted with only one buckle (not sure if this means anything).
The black piece at the top of the main shaft has 2 little stubs that stick out and fit into pockets of the main rotor assembly. If one or both of these is broken off it allows the head to slop around way too much, cause the problems you describe as well as allowing rotor to rotor strikes between the main rotor, and the lower rotor.
Just fixed this problem on a heli, ordered a main shaft assembly, and to make it easier just moved the top plastic piece from the replacement part to the old shaft that was already in the heli. (the screws are TINY and easy to lose so be careful)
thanks 4 all ur help. it now flys perfectly
I just opened my sons new s107G. worked fine for 5 min. Then it now only response to the remote if the remote is with in 5 inches of the tail before it loses contact. I tried to kill battery then recharged it. I also changed batteries on control but nothing seems to work . Any ideas. Please help.
Are you flying near anything digital like TV? also infra red remote hates bright sunlight
Hi guys!just flew a few times with the S107G and everything went well..but when i turn on the remote now, the power charger light on the remote is red and stays red so i can’t control my heli..
I already changed batteries and recharged the heli via USB but it still doesn’t work..any suggestions?! 🙂
thx
I got a s107 a couple of days ago and worked just fine. Today I tried to play it again but it doesn’t fly any longer. The problem is the top blades is not spinning (the bottom blades and tail rotor are working well) I fully charged its battery through a UBS but to no avail. Performed a couple of testing. When I move the top blades with my fingers, they engage the gears just fine; however, when I use the remote the motor that drives the top blades does not engage. My initial guess was that somehow there is a wire dangling that connects to the motor that operates the top blades. I inspected them carefully but there isn’t any wire dangling. According to my gut feeling, somehow either its rear motor or its circuit board is out of order. Is there anyone who has similar experience in the past? Any suggestions? Thanks in advance.
hi john, did you ever get an answer to your question? I have the same problem with mine, the top blade is no longer spinning, let me know thanks and HNY
bill
Might want to take a look at the gears on the end of the motors. I believe each motor controls each set of blades. May be that the gear for that rotor sliped off.
If manually spinning the top rotor spins the gears as well as the motor, and the bottom rotor spins, theres a chance that the circuit board in the heli has a problem. I’d check the wires from the non-working motor to make sure they’re good (test meter resistance check make sure neither of the wires are broken)
If you can eliminate a bad solder job, loose wire or broken wire, might try replacing the board. Its in charge of “mixing” the voltage IE since the heli steers with torque, it controls how much voltage goes to each motor. The voltage is adjusted for turns and nudge by the trim so that you can get a neutral turn rate.
If the board is toast, its probably sending all the voltage to the lower rotor motor, or else its still trying to mix but the power for the upper rotor just never gets there. (Another thing that can be carefully checked with a test meter) Its also possible the motor itself died. (hence checking to see if it is getting power or not before buying a replacement circuit board)
I got A AIR SHARK 2 HELICOPTER AND THE BACK PROPELLER WONT MOVE IT DOES NOT GO FORWARDS OR BACKWARDS AND PEOPLE ARE SAYING TO BRING IT HERE AND THERE BUT CAN I FIX IT AT MY HOUSE IT IS NEW I HAVE ONLY HAD IT FOR 2 WEEKS AND ITS DONT WORK ANY ADVISE WOULD BE A BIG BIG HELP!
My main wings are drooping way too low and causing the heli to crash after a few seconds in the air. The top (main) wing literally hangs low enough that it touches the bottom wings even when the heli is off. Any help would be GREATLY appreciated. Thanks in advance.
BTW i made sure the connect buckles are over the balls, i tightened the screws in the upper assembly, it seems to me that the weight bar might have something to do with it since it hangs to one end or another.
please any help on this? I can link a picture if it would help.
This helped me fix the same problem.

Same problem as I mentioned in another post here. Check out this thread. http://syma107.com/forum/general-syma-s107-information/blades-colliding/
The 2 stub shafts that go into the pockets of the main rotor assembly are most likely sheared off as mentioned in this posted thread.
HIS IS MY EMAIL IF YOU GOT ANY THING MICHELE.MARSDEN@VERIZON.NET PLEASE SEND ANY WAYS TO HELP ME
EVERYONE– LISTEN UP. DO NOT BUY THIS HELI-COPTER. IT DOES NOT MATTER ANY-OTHER RATINGS. AS YOU ALL ARE SAYING, YOU ARE HAVING A PROBLEM CALLED THE “TOILET BOWL EFFECT” IT IS WHEN YOU ARE JUST PUSHING THE THROTEL UP AND WITHOUT TRYING TO MAKE IT GO AROUND, IT GOES AROUND AS IF SOMETHING WERE PULLING IT IN.
I DON’T KNOW ONE USER THAT HASN’T HAD THIS PROBLEM. THERE IS NO SOLUTION TO THIS PROBLEM, EVEN IF SOME PEOPLE SAY THERE IS. I HAVE BOUGHT THREE OF THESE PLANES OVER THREE MONTHS. ALWAYS, AFTER ABOUT 10-12 FLIES IT STARTS TO DO THE “TOILET BOWL EFFECT”. I HAVE TRIED ABSOLUTLY EVERYTHING. IT JUST DOESN’T WORK. THE OLD SAYING IS REALLY TRUE- “YOU GET WHAT YOU PAY FOR” IF YOU’RE GONNA BUY A CHEAP $30 HELICOPTER DON’T EXPECT IT TO WORK. IF YOU STILL HAVE WARENTY LEFT– RETURN THIS BEFORE IT IS TOO LATE. IF YOU ARE GOING TO BUY THIS- DON’T. YOU WILL BE DISAPPOINTED, AND IT IS A WASTE OF MONEY.
All the ratings are wrong. Just look at the other comments, they all go a bit like this…
I got this S107 for my son/daughter for *holiday* and it worked just fine, and great for like 10 charges, but then it started twisting around and crashing, how can I fix this?
Every-time it happens. Save yourself, don’t buy this.
@The Guy, Every one has a right to voice their opinion,rather it was not in caps just rude.Thousands of Syma helis per week sold on Amazon,their best selling product in toys with small return problems-My question to you is where did you buy your helis from?I feel it is also a big statement to say you do not know one user that has not had this tbe problem,I never had that problem and last count own over 40 of them,until the heli has a bad crash,then you repair and carry on-Yes it is only around $30, I have helis over $1000 each and need repairs often to keep flying,that is the fun of the hobby-Take care SF
@GUY. I own 4 S107’s and have sold over 30. Are your helis Real or fakes? The main problem is when people crash them they dont let off the throttle and break the top buckle. So what your saying is I drove my car into a tree and now it doesn’t work so dont buy a chevy/ford.
mi heli was workin great until un day it started to spin,any sugestion.I realy liked this heli and i whant to repare it.
Spin as in, like a toilet bowl or spin as in standing still and spinning around the main shaft axis?
If it’s doing the toilet bowl effect, I can’t remember the fix, but Google it (or TBE) you’ll find it. As for spinning on it’s axis, make sure the leading edge of the blades aren’t nicked up. If there nicked real bad it will cause extra drag on one set of blades (usually the top) that can’t be fixed with trim adjustments.
I take a pair of scissors and lightly scrape the nicks off (use one blade of the scissors. NOT like your going to cut with them). Almost like your sharpening the edge of the plastic blade like it’s a knife. Just remember, very lightly, you just want to remove any plastic burs. If that sounds to complicated (or you have no idea what I’m talking about) but your blades are nicked up real bad, just order new ones. I got some for .70 cents on Amazon and a few bucks shipping.
In our case, mark is right about the horizontal posts on the shaft being broken. One post fell out as soon as I disassembled, now I just have to figure out how to extract the other side that is stuck inside and get a new one. Thanks mark!
Cheaper than elsewhere:

You can push the post out through the other side. Blue skies!
Billy is right on…cheapest that I’ve found those inner shafts, and free shipping. Ordered a few extra just to have on hand!
Whilst flying my little red beuty it developed a sudden fault. For no reason atall it began to fly in ‘drunken’ circles with became worse when steering. I have not crashed my heli and am seriousl concerned
My son received a s107 for Christmas, it worked wonderfully at first. Now that we have had it a few days the silly thing will not lift off. It acts like it is going to but it won’t. We have tried everything. Any suggestions?!?
If it starts to go off, but will not maintain altitude, charge it for 45-50 minutes. Then you can use for 7-9 minutes. Then you must charge again.
I bought a Syma Cobra (S108G) for my son for Christmas. Has been flying great (maybe 20 charges worth) up until now. For some reason the tail rotor is not spinning any longer. I did pull the rotor off and clean out some fuzz (from one of the crashes) thinking that was the cause. I don’t think it was now since the blade does not spin. Everything else on the heli works and it still hovers, just no forward/backward motion. Any ideas? I’m not one to just open it up and try to figure it out but, don’t mind if anyone has a suggestion. Thanks in advance. T-
I am having the exact same problem with a s107 mini we just opened yesterday. I was amazed how well this heli flew and was so excited but now it’s been short lived. I too look forward to any suggestions you might have.
In my very limited knowledge, my repair guy explained that the rotor only spins when you want to turn the coper left or right. Otherwise it does not spin and has no control of forwar or backward. That would come from tilting the blades which is a completely different mechanism. Hope this helps a little.
Tortuga, I would check the wires that go from the heli to the rotor motor and or the connection on the motor. If the wires are good then either the motor went bad ( you can find a replacement on amazon) or the wires from the motor connecting to the circut board in the heli.
On the S107’s the blades dont tilt like a regular heli. The tail rotor only spins if you want it to go foward or backward. The tail rotor spins up pushing the nose down and heli flys fwd. Same with the rotor spining down pushes the tail down and it go backward.
Thanks for the info. I will check out the wires and probably go ahead and order some spare parts from Amazon. These things are tons of fun but, a little frustrating when you have an 8 year old wanting to fly all of the time. Guess I’ll pick up another S107 when I order the parts. Happy New Year!
Does anyone know if the horizontal stablizer (triangle shaped wings midway between body and tailfin) of the S107 can lead to unstable flight. I wasn’t sure if this was only for decoration on these small helicopters or if they actually do serve a purpose. My S107G is unstable after the stablizers broke off so, it makes sense that they do help with control but, maybe something else got knocked loose in that last crash. Thanks.
The little triangle your talking about isn’t required, but remember that parts that are missing or moved can case the little chopper to become unbalanced.
Hi:
The heli. was flying fine out of the box but now when I lift off it tips to the right about 6″ off the floor and crashes. I have tried trimming but it doesn’t help. Any suggestions….Thanks
most likely broken head on the inner shaft. Should be two horizontal posts coming out of the head that nest in the top blade brace. Held on by horizontal screw above top blade assembly. To find replacement, search for “Syma 107 inner shaft”. Most people simply remove the head from the new shaft and replace existing. Takes about two minutes. Good Luck.
@Mark, Very well put.
I think I’m having the same problem. It seems that the balance bar whacks the blades when powering up. What does the head look like? There appears to be a square spot on top of the shaft with a knob that looks as though something might snap into place there. It that what we are talking about? Is that the purpose of the head? To steady the balance bar?
Mark or Anyone,
How do you get the head off the new shaft?
Pliars? Does it take a great deal of force?
there is a small horizontal screw above the top blades. It secures to a flat spot on the shaft and holds it secure. remove the screw and the head should come off easily in your hand.
I bought the s107 as a christmas present. The s107 had the best reviews. Especially that it was very durble. However after the first few flights (which were really cool) and a couple of very minor crashes on a carpeted floor from less then 2 feet while trying to land on a card board box, it is all messed up. Now every time it takes off the blades collide and it crashes. I have read all posts and checked everything out. Nothing seems loose, broken, bent or missing. I ordered a set of replacement blades, fins and stabilizer bar with the heli. I have replaced all parts and it still does the same thing. I now have two sets of damaged or broken blades and an inoperable heli. At least I only paid around 30 bucks from amazon. Oh well, it was fun for about 5 minutes lol. As far as being at all durable, I have to disagree. I guess the kids will have to enjoy the video games instead, at least they last longer than 5 minutes.
Crashes are not the helicopters fault but the pilot-try bending your main shaft by hand gently as hollow to be straight
Had the same problem. Found this fix.

@Jason The part from that post wasn’t a Syma S107 part! First, I’ve never seen that problem in spite of plenty of brutal crashes from as high as 50 feet (that’s right, 50 feet – outdoors). So I took apart a heli and compared the part. Different! I’m in a hurry and can’t easily figure out to post it, but I can describe it. There are three crossbars. Top, middle with screws and bottom. On a Syma the top bar is 45 degrees from the others. And the bottom flange is narrower. That’s why that part is shearing! It’s apparently not a real Syma. Does yours have a red circuit board with S107R5 on it in white letters?
There are two screws in the pins that seem to stabilize upper blades. Could these be adjusted to stop the blades from clashing on every takeoff now.
My 107G was prefect until only a few crashes also.
It does have a red circuit board with S107R5 and under that it says SMLBH. The problem was the posts that the upper blades sat on had snapped off. It fixed my problem.
@Jason. Excellent Link! This is a Syma 107 part. I’ve replace 2 of them myself. Thanks for the link its hard to actually explain how to do it.
How does the Syma s107 compare to the Estes copters?
Probably not much-I really do not know,why would I buy a copy-maybe you should buy it and find out-Why would you tho when there is so much posted here by great guys on the Syma S107,maybe I am missing something here-lol
When I asked about the Estes I was already sold on the Syma S107!! At the time I didn’t know about all of the replacement parts and information available.Estes should probably stick to model rockets anyway.Their Heli looks the same for twice the price and not as much info on trouble shooting and repair.Thanks for the reply and all the helpfull info.Now Im off to buy 2 Syma S107 Helis for twice the fun!!!!
I would say…from experience…most likely broken head on the inner shaft. Should be two horizontal posts coming out of the head that nest in the top blade brace. Held on by horizontal screw above top blade assembly. To find replacement, search for “Syma 107 inner shaft”. Most people simply remove the head from the new shaft and replace existing. Takes about two minutes. Good Luck.
Our boys each got one for Christmas. They lasted about 20 minutes total. Really they shouldn’t be on the market. It was the gift the boys wanted the most. It gets airborne and then the blades seem to crash into each other at the top. Both the same. We live in the Caribbean and shipped them over from the US. So yeah, pretty annoying when I see that this happens a lot. Should have checked the reviews first.
Where did you buy them from?In the total 20 minutes of flying them I would imagine your boys would have crashed them a few time if beginners,that of course leads to checking what is out of aline or damaged.There are some minor things that go wrong and can be fixed with a screwdriver,if you view this blog comments and forum you will find a fix for your problem.They are a fairly complicated toy to use such a word with many moving parts including a pcb board,simple things like hair wrapped around shaft will cause flying problems. I have many helicopters some that cost over $1000 and always need some work on them after flying,that is the nature of rc flight hobby and repairing them is also fun-let us know where you purchased from so we might determine if a genuine Syma
Emma, sorry to hear that. The Syma’s are excellent little helis. There is a part that tends to break in hard crashes when the pilot holds the throttle on to long. Jason has an excellent link above that is more than likely the problem.

I have a question – Just got a S107 for my son. Worked great for about a day, but then the helicopter became unstable. It will take off and just veer off to the side, the blades start smacking each other, and heli crashes. My son says that the top rotor is “wobbly”. I’ve looked but can’t seem to find anything broken. I’ve tinkered around and can’t seem to pinpoint what is causing this, but the top rotor is indeed wobbly. Can anyone tell me what part, or parts, are bad? Any advice?
Check to see if you lost a connect buckle, should be two connecting the balance bar and the top blades. Same thing happened to ours, found a replacement pair for $2.50. Good luck.
Steve, just a note I have the same issue so if you get a answer please let me know. Blackhawks Down.lol
I have the exact same problem. I still have my connector buckles and when I clip them on again it still crashes. Do I have to buy new ones or can I fix it?

Hi Don –
HELP! Just recd a pair of these for my 8 and 5 yo little fellas. One of the copters just started doing weird stuff ( i think another post referenced as “toilet bowl effect”) – It’s like th gyro is all messed up. Once the rotors get up to speed, and liftoff, the copter’s “top weights” start going nuts, spins the copter into circles then crashes. (not tail spinning around, but the entire copter).
Any advice? Try returning to amazon or something?
TBE is usually the connector buckles, the little T-bones on the top assembly. There is good info on TBE around. It’s always something in the upper assembly that attaches to the top rotors and the flybar. The connector buckles should sit lightly on the balls. Sometimes it’s more complicated.
My wife bought my 10-year old daughter an S107G for Christmas. Big hit with us all and a far superior product to the heli my wife bought me 3 or so years ago at about the same price.
The Syma worked flawlessly through at least 6 or 8 flying sessions. Now on an apparently full charge (we charge via USB from an iPhone cube on a wall socket) the heli simply hovers two or three inches off the ground at max throttle. I suggested we run the heli battery to empty, wait a bit and then recharge. (I don’t know the characteristics of Li-Poly batteries; with some types this matters.) We did this but are getting the same result. Thoughts?
One of the posts somewhere suggests letting the heli “cool” after use before beginning to charge in order to preserve battery life. This was probably not done yesterday. Hope we didn’t shoot ourselves in the foot by not practicing this.
I flew the heli myself last night after the kids were in bed. It seems a very well engineered and built product. Hope we can get ours working again!
I’m having the same problem. Mine won’t even lift off the ground. We noticed it was flying lower after 7 or 8 flights and thought it was the battery. The parts appear to be intact. We may return it to Amazon…
Check the intermediate gears for both main rotors. When I have this issue it is because one or two teeth are missing from the smaller side. A rotor crash will cause these to shear off. Not difficult to replace…
Hi! I bought a Syma 107G recently, it was flying all ok. All of a sudden, it stopped flying. As soon as it take off from the ground, it start a rotating motion and the balance bar and the top blade hit together and falling off. Could some one give me a tips as what to do to repair?
Mine is doing the samething…have you had any replies or found a solution….
Check the connect buckles. Should be two connecting the balance bar to the top rotor.
Am I missing something? I bought 2 SYS107 helicopters for my grandsons. They need to be on different channels to be flown simultaneously. Switch on the contoller is simply switched to A or B but where is the corresponding switch on the helicoptor itself. Would think it should be obvious and accessible . Maybe I’m blind but there is no indication on the instruction manual.
Regards
There is no corresponding switch on the heli. And B is bogus, pick A or C. Set the switch, turn the controller on, then turn the heli on. The heli will bind to the correct channel (A or C) and then the green light will change from blinking to steady. Move the trottle (left) slowly up and down to engage.
Here is what you need to do to fly two simultaneous. turn on first heli, turn switch on first remote to “A”, power up heli briefly. while not making any movements with first remote, turn second remote to “B” and turn on. Turn on second heli, give second heli some throttle. Now both heli’s are synched to the different channels. You will have to do this every time that you fly two, but you will get it down to where it takes 2 seconds! Good luck!
there isnt any switch on the heli for a different channel. the heli locks on to what ever channel is available. a or B. try turning one on letting it lock on. set the other remote on the different channel ( taking the other heli 50 ft away from heli #1 and let it lock on to the other channel. bring them together and your ready to fly.they are really fun using 2 heli’s at once.
Have fun
I just got one of these for Christmas as well. I like them so much I want to order a second one but was confused about how to go about ordering one that is on CH B since they all seem to ship as CH A. Obviously I haven’t tried this, but I’ve read online that you only need to flip the channel switch on the remote with the heli turned on and in view of the remote. Here’s the quote I found from an owner on Amazon. “On the bright side is that to change channels, you just have to flip the switch on the controller and the heli will automatically recognize which one you chose. ” There are only two channels, though. CH A and CH B. Apparently at this time CH C is not used.
James,
I had the same problem. 2 kids, 2 helis and both were controlled by the smae remote. What I found was, the heli automatically locks in on the remote. Set the remotes to the different channels ( A and B) and start up the helis in different rooms with their respective remotes. They should look in on the closest.
Hope this helps. I’m first timer myself.
@james There’s no switch on the heli. Set the switch on the controller to A or C (There really is no B). Turn the controller on. Then turn the heli on. The heli will bind to A or C depending on the controller setting and the blinking green light will go solid green. Move the throttle (left stick) all way forward and back to activate and off you go.
Here’s what worked for me. I changed my S107 from channel a to b using the following steps: 1. after fully charging the helicopter, power it on, then power on the remote. 2. Wait for the blinking green light on the inside of the back of the helicopter to stop blinking. 3. Slide the switch from CH A to B on the remote. In a second or two the helicopter should respond to the controls automatically. Now you have a helicopter on Channel B.
Got a new s107g for my son for Christmas. Flew fine for most of the day. Now doesn’t seem to start. Thought it was a connection problem, but green light goes from flashing to solid, still does not start. Any thoughts? I did leave the remote on once while the 107 was charging, so I suppose it could have drained the remote batteries, although the light on the remote tells me that I still have power. I’m going to be bummed if this only lasted a day and I have to buy a new one 🙁
@iball Move the trottle (left) all the way forward and back. It takes hours and hours to ruin good batteries just by leaving the controller on.
@iball Unless the batteries were already old, leaving them on during a charge won’t hurt much at all. I’ve done that more times than I can count on one set of batteries.
I am wondering if I can use my ipod charge unit to connect the USB cable instead of running the USB cable in to the computer??
I would not. iPhone batteries are Lithium Ion, 1400mAh 3.7V while the 107’s batteries Lithium polymer 150mAh 3.7v. probably fry pretty quickly. Good news is replacements are $6!
I’m not an expert in Lithium polymer batteries, but from my experience you can charge the helicopter from other USB sources, as long as your adaptor is rated at 2.5W or 500mA or higher. The charge status light seems to only work if you are using standard USB current, however. (500mA) Other adapters that put out 5v at 500mA or more should work. Every device that uses a lithium polymer battery which accepts external power for charging its batteries must have built-in charging circuitry. Unless the charging circuits on these helicopters is complete crap, which they are not, then they won’t ruin your batteries by feeding them more current than they will use.
The comment from Mark about the number of mAh makes no sense because this is a measurement of how much power the battery can supply, and has nothing to do with requirements for charging. 1400 mAh means that the battery can supply power for your device and how much power the device uses dictates how long the battery can supply power. For example a device that uses 1400 mA of current should run for one hour, whereas a device that uses 100mA should run for 14 hours. That is the only meaning of the mAh rating on a battery. if the Helicopter’s battery is rated at 150mAh and it flies for about 15 minutes of continuous flight or .25 hours then you can calculate (.150A/.25h=.6A) that the heli is using about .6A or 600mA during continuous flight. You use this calculation to see how using a battery with a higher mAh rating would give you more flight time.
The chopper flew fine for the first 5 mins. But after the charging session it only twichtes then all the lights go out on the chopper. Continuously tried charging and operating and everytime get the same result. Is it defective or is there something else I’m doing wrong?
@Len Please describe the charging session (controller or USB, what the USB cable lights do, how long it takes for the light to change, etc. Sounds like it might not be charging.
I’m actually having a similar problem. I’ve had two of these for months and then today after a full usb (via computer) charge took off flew around the room and then all of a sudden it fell out of the sky dead. LED’s were still flashing but no reaction to throttle. So I turned off the heli and controler to reset (usually works) and now all it will do is start the blades with a twitch and then the led’s stop and its dead in the “on” position. Tried letting it sit and made sure it was charged (charged again till red light came on) and then it took off (about a foot) and went dead again. I can always switch it off and then back on and the led’s start again but if the blades twitch spin it just dies again.
The second one is flying fine but it is starting to just loose power mid air and come right back and work fine and then it will happen again all of a sudden. I’m wondering if there is some kinda of controller interference or something. I checked the controller batteries today and they all test good. Any ideas?
Definitely solder problems here… the toy is a hoot. my 5 year old loved it… took plenty of crashes.
After a few flights, the ground wire of the aft motor became disconnected from the board. Looks like that’s a place where two wires are soldered into one perhaps? With tight clearance and no ability to solder what so ever, I opted to just splice the broken wire into the red one next to it by peeling back some insulation and wrapping. Works now.
The soldering looks like crap though. But for less that $20… what do you expect.
is their an helicopter that fly’s longer than (six minutes)?
would be more fun, cause 6 minutes is very short time to play with something for a kid to have fun on Christmas time length is way too short.remote control car/trucks can go for days.I just knew this helicopter would be close .but it is no where close to it at all. 🙁
@Teresa 6 minutes is a good flight time. The tradeoff for getting so much power of a little LiPo battey is that they can’t fly that long. On helis with batteries you can replace quickly, you have to be careful not to overheat the motors. So, 6 minutes it is, and be happy.
@Teresa 6 minutes is a good flight time for these small helis. The tradeoff for getting so much power out of a small, light LiPo battery is that it can only run for so long on a charge. Also, the little motors will overheat if they run continuously much longer than that. That’s pretty much just the deal with these little helis. Even with the (much) more expensive ones. The way to get around it is just to buy several.
I gave my grandson a S Gyroscopes system 107G metal series 3 channels infrared RC mini helicopter for Christmas.is their any way to get it to run longer than 6 minuets.If so I would like to know…..
Thanks
Sorry, but 6 min is about the average “fly time”. The unique small size of the copter limits battery size and capacity as well. The good news is, you can purchase more than one copter to have “at the ready” while others charge!
I have the Syma S107 and it will not bond with the transmitter on any channel, the transmitter just keeps flashing green. I tried your advice from above and still dosnt link up. Any other suggestions? Thanks ahead for any help you give.

I bought two of those- one for each of my children. The problem is both copters answer the same remote. No matter what I try, I cannot get either to recognize the other remote. Obviously what I wanted was channel A with remote one and the other on channel B with remote two. Any advice?
@Alex There is no corresponding switch on the heli. And B is bogus, pick A or C. Set the switch, turn the controller on, then turn the heli on. The heli will bind to the correct channel (A or C) and then the green light will change from blinking to steady. Move the trottle (left) slowly up and down to engage.

Hey man I read about 90% of your article (didn’t read the sales sect), but I’m still having trouble flying it. I think its one of those “fakes” that you spoke of. When we try to fly it in the air, it will last about 0.5-2 seconds then crash unexpectedly. It appears that the top rotor (stabiliser- i think thats whats its called) is hitting the bottom rotor causing it to fail. Is this common? I don’t think its meant to fail in Mid flight.
hi don bought a syma today after charging it i acan get it to fly upwards but dese not go forwaard or reverse. it wil turn left and right. is the a simple fix or take back.
@Jack Probably take it back. Never heard of that one before.
Same problem with blades tangle and crash. Worked fine for several days, and runs fine when held, but crashes immediatly when released. Ball joints seem to be connected properly.
Almost has to be something with the upper assembly. Nothing else could *allow* the blades to tangle. You should be able to rock the flybar by blowing on it. Make sure the assembly is snug on the shaft. Make sure all of the blade grips (top and bottom) are intact and the screws are snug. There shouldn’t be much up and down travel at the tips of the blades.
same thing with the tangled blades… and now the top one falls down the shaft onto the bottom blades…if i just buy a new shaft will that fix the problem?
Hey just wondering if you’ve come to a solution to your blade clashing problem. mines doing the same thing, I was wondering if I could maybe superglue a shim in? It seems to be loose around shaft.
Got one for my daughter for Christmas. After playing with it in the house for a few hours, off and on, it started crashing all the time. We found a connect buckle that had come off, but when we reconnected it it still has problems. The top blade assembly seems a bit loose, like maybe we’re missing a part, but I can’t figure out what it is. Screws all seem tight enough. If I wobble the heli while holding it with the blades spinning, the top blades can touch the bottom blades, which is what is causing it to crash. Any ideas?
I got a red S107G gyro helicopter fore Christmas. It worked fine and then I had the blade tangling with the balance bar problem. I read Don Draper’s reply but it did not help. We have a Heli Store here so I took it in. The owner was very familiar with these copters and immediately diagnosed a borken shaft. There is a small short horizontal shaft that goes through the verticle shaft to stablize the top blades and the balance bar. He said if you hit it just right on a crash (I had many), it will break. He had a new one in stock and replaced it for me for $5.00. If your top blade is “floppy”, this is likely your problem.
no luck fixing it. The bones are connected, all the screws are tight and nothing appears bent. It will run on the table but starts going backward. The blades tangle as soon as it lifts off.
Ive the same problem – Lasted 5 minutes out of box – must be a design fault – very poor
After a many crashes, both my helis have the same problem. It appears that the rods that hold the top blades have snapped and need replaced. Anybody know which spare part that is? It looks like #13 from the diagrmas but not sure. Is there instructions somewhere on how to take them apart and replace broken pieces?
Seth
hellbender7@hotmail.com
When it’s on the table are you getting full power to the top rotors?
I keep seeing this problem on forums, I had the same problem, then I found this solution. The rod that holds the upper blades stable breaks off, but you can carefully drill it out and insert a wooden dowel to replace it. Don’t forget to drill a smaller hole in the dowel for the shaft to go back through.
http://syma107.com/forum/general-syma-s107-information/blades-colliding/
top rotor spins fine, but bottom rotor does not spin. tried everything, but not flying only spins. Fixable or take it back?
I’d say take it back.
Had the same problem. Upon closer inspection, I found that the motor and gears for the lower blades were not spinning. Replaced the motor from a parts copter and it was flying fine again. If you just bought it, I’d return it unless you have a parts copter lying around.

hi i buy one syma s107g but dont fly but ist on and the control tooo ist on and dont fly help meeee
Make sure the heli is charged (red light on the USB connector bright red), and the green light is on on the controller. Make sure the ABC switch is all the way to the left or right. Hold the controller 3 feet from the heli. When the green light on the back of the heli is solid, push the throttle (left stick) slowly all the way forward and back. If it doesn’t fly then, return it.
me compre un syma s107g se prende pero no vuela ayuuuudaa
