Syma S107 Modifications
Syma S107 Modifications:
There is a few, however the only one I recommend to get the forward and reverse on the Syma to be faster is to change the rear rotor blade to a Picooz tail rotor blade. I found this video below-you need to invert the tail motor with the Picooz tail blades-more to come on this as in process of testing this concept. Let me tell you this little bird is really ok without any mods-but If you are like me you will eventually want more speed. Just experience what you have first. Picooz Tail Blades Link
Another video of tail motor mod
Another modification is to take out the throttle spring that from factory has a fair bit of tension and flicks back to no throttle if you take your finger off the throttle control-My advice is to just fly the Syma 107 for awhile before changing anything until you want more control- video below from YouTube--
Hacking battery to a 150mAh battery-Cool idea-Not something I would do on your first Syma S107.
Extra Navigation Lights- Sorry to say I have no idea how to do this- not LED Master! Interesting tho.
Please be careful doing any mods could screw you Syma S107 to the burial ground- lol

From Don--
I really like your controller modification to change the power lever from spring action to resistance. Clever. I wanted to let you know that I discovered you also use the variable resister on the right side at the bottom of the joystick mount to center/adjust the forward/reverse action. On my controllers, the lever had to be pressed too far forward before the tail motor spun up. Now it only has to be a little forward. Much nicer and more controllable. I don't know if you knew about this mod. It really helps fine control greatly.
Don- Thank you D really love your feed back-SF
----------------
Also, I fixed a bad case of TBE (Toilet Bowl effect), where the heli "swings around in a circle" instead of hovering in one place- by tightening the bottom blades.
If you want to use this tip and/or the one about the controller mod on your site I can write them up nice and maybe even to a video on the controller one some day.
Don-Mate we need your video-great work -SF

Point to mention-If you are going to do any modifications I and Syma manufacturer are not held responsible for your mods-Do not do mods and expect a warranty on your Syma S107-Just beware you are on your own with any modifications you do to your Syma-

If you use this heli a every day will it stop working?
The battery of course will need replacing eventually if flying everyday, also to preserve battery let it cool for 15 minutes before charging
No, it will work for the rest of time until the sun consumes our planet.
Excellent reviews I’d like to know what kind of lights used? Where can I found those LEDs lights?
I’ve tried all of the speed mods including the flybar. The newer flybars make it impossible to remove weights without cutting plastic and throwing out of balance… But I did come up with a different mod that I haven’t seen anywhere else and I wanted to share. I’m surprised no one else has posted this. Or at least I haven’t seen it.
The Picooz tail rotor blade was disappointing for all of the trouble (finding, purchasing, inverting motor, etc.) It didn’t give me the improvement I hoped for. However it did inspire me to try making one of my own. It turned out to be one of the most effective and simple mods I’ve tried. In fact, if you do only one mod at all this should be it. All you need is some masking tape or painters tape and a pair of scissors. Simply fold the tape over the stock tail rotor blades and trim to shape. The added weight is negligible and it can have a dramatic impact on acceleration and cruising speed. The best part is that you can experiment with different sizes, shapes and curves. Fun stuff. (Hint: If you extend the length of the blades too much the thrust gets countered by main rotor downwash. Best to keep to stock length)
Here are a few photos. Not very good but you’ll get the idea.

I own a few 107s so I like to try different mods side by side. I always keep one stock for baseline comparison. This is the best mod i’ve tried yet. Especially when combined with other mods. I may post some video someday when I get around to it. But I wanted to share this and get it out there. It’s a great mod and I haven’t seen this posted anywhere. And it’s super easy to do. Have fun!
(Nitro planes. com) has a load of helis from Syma. They also have all the parts and mods. If you love to fly check out this site. PS. I bought the S107 from them and only paid 16$ for it brand new. not a clone. Enjoy your flying…
Had a look at the site was not able to buy a Syma 107 for $16,more like $25 plus,maybe as in Australia
Hi,
The wires from the circuit board to the battery have come off the circuit board. I can’t see where they came off. Can you give me a diagram of where I can re-solder them on?

i recently got into the Syma 107…i started with the Syma 033G.
there was an immediate diference! i had lots more control of the 107.
i flew the 107 for a while with the throttle in it’s ‘standard’ configuration, with the spring in place and then removed the spring as per the video; make some difference. i’m able to set the throttle and leave it until change is called for. i like the mod.
so far, that’s the only mod i’ve made. i willcontinue to fly it that way until i see a need to change. i think the standard 107 is a pretty stable, well performing, aircraft “As is”; time will tell…in my case.
After only a couple of days and not too many crashes, it no longer hovers steady, it kind of sways around about 0.5 to 1 sec per rotation. I don’t see anything broken. You see the two rotors swaying when I hold it.
did you try adjusting the trim? (the small, round knob in the center of the control)
I also had a similar problem. My bird needed a new main shaft.
Small pieces broke after a hard crash. Just replaced the top piece,, not the shaft.
It was easy. My bird is flying again for only a few bucks.
Here is a forum link that should help all on repairing your Syma S107
This has been posted to the forum already, but the answer does not seem to match my problem. My son received an s107 for Christmas and we love it. But, it will not move forward or backwards any more. The rear rotor seems to be spinning, but I cannot detect a change in speed (motor whine pitch) with movement of the right throttle on the remote.
Any help would be appreciated.
Check main tail rotor not spinning on shaft,must be tight fit
OK. I have super-glued the tail propeller to the shaft and made sure that the wires connecting the tail motor to the main circuit board are intact. Now the rear propeller spins all the time the helicopter is turned on. I still cannot move forward or backwards though. Rotation is fine as is accelerating the main rotors for altitude.
Any ideas?
There are two posts connecting the top two propellers to the main shaft that broke. Check your main shaft against pictures of a new main shaft. You need a new main shaft. The same happened to me.
Hi guys,
Since the Picooz tail rotor blades are all sold out, I was wondering if there is any other place to buy them. (None on Amazon). I was also wondering if there are any other tail rotors that may work for the speed mod besides the Picoozs.
Thanks!
http://www.amazon.com/gp/product/B000PW00K8/ref=oh_o00_s01_i01_details
they’re the same as picooz as far as I can tell.
I was thinking of making a cheap toy-ish quality rc UH-1 Huey, and from looking at it, I think one of these would make a great base.
I saw on amazon a set of two for $20, although they’re probably not real ones… http://www.amazon.com/gp/product/B004ZSU7ZQ/ref=as_li_tf_tl?ie=UTF8&tag=syma107heli-20&linkCode=as2&camp=217145&creative=399373&creativeASIN=B004ZSU7ZQ and a perfect Testors ready-to-assemble kit of a huey that I’d need to repaint and modify.
My question is, do you think these could handle removing the tailboom and fuselauge, extending the wiring to the tail motor to put in the tail of the huey, moving the light, and adding the extra weight of a huey body?
thanks!
(just a thought: if they make blackhawks, chinooks, cobras and apaches, why in the world do they not make the one I want???)
wait… might change from putting on top of tail to doing speed mod…
Guarantee it won’t go very fast at all, even if I trim the huey body as much as possable…
Also, $13 on amazon for the two, and they look real, so I’ll probably buy them soon.
thanks again!
Ok, whent to order hte stuff, and the $13 two helis is really a rip because of a hidden $40 shipping.
Will keep posted on progress of the Huey mod…
Also, I’m going to replace the rotors (main and tail) with larger ones from the “double horse”. Would put more strain on the motors to move, but would require less rpm and would help lift the much heavier body
I was looking on amazon and I found the s107 and another heli and I searched the s107 and watched a lot of videos and I already know I want it and knowing what is fake and whats real thanks
And I love the battle drill u guys did great with the graphics 🙂
Have a week old s107 and notice the TPE already. Knuckle joints seem fine, but as i can’t find an exploded view of the shaft to knuckle connection, i removed both knuckles and the upper prop assembly fell down the shaft. Is this assembly only held by the 2 dog bone knuckles?
any links for details on repairs in this area?
thanks
Rick
If understand what you’re describing…no it isn’t just held on by those two dog bone knuckles. The main black piece that the top rotors and balance bar are all connected to has two small black points that stick out which act as an axle for the top rotors. Yours probably broke on one or both sides (mine did the same thing once). I ordered this on amazon… http://www.amazon.com/Syma-S107g-13-Helicopter-Replacement-Part/dp/B004N37Y8Q/ref=sr_1_1?ie=UTF8&qid=1324914104&sr=8-1 and just took the part I needed off the shaft. You can see the piece I’m describing in the picture, right underneath the top screws.
Hey,
not sure if you already got this figured out… but I just had the same issue.. it was causing the copter to crash when power was applied to try and take off. The top set of blades/gyro was very loose. It turns out that there are two small plastic cylinders inside the piece that comes apart into two parts (also the free floating part you mentioned that is only connected with the dog bones). The two plastic cylinders are about .065″ diameter and I found that mine were worn. I replaced them with string trimmer line of the same diameter and cut them to .15″ and installed them. This was a bit tricky but it did the job and I got my stability back and am flying again. Hope this helps someone that is in the same situation that I was. I should have recorded a video but I was not sure at the time if that was my problem.. it was. Good luck!
Hello, my tail rotor will not spin? I think it is the motor that isnt working.
What can i do to fix this?
simple changes Avolar piece jejeje
@Robert hold heli give it throttle push for forward motion does tail motor spin-also check tail rotor fixed secure and not spinning on shaft-keep us posted
@Syma Freak Thanks for the response but I taken it apart by taking the front casing off and discovered the red wire going to the motor was broken off the solder joint! So problem discovered but not solved! I can solder but its so small a joint that its kinda hard. Any tips on easy joining for the wire to the solder joint? I asked my dad to take it into his workplace and ask someone to solder it for me, as he is a teacher he has many technicians in his school so they could possibly do it.
All the tips you given me i actually tried before i discovered the broken wire!
Thanks a lot for the help!
Keep posted 🙂
@Robert Great news you found the problem-have sent you a direct email with some advice on soldering-hope you get it ok
@Syma Freak Thanks for the email help! And I cant be there, got school still, but will tell my dad to take it into his school (Different school to mine) and one of the technicians may be able to fix it.
Had the same problem with my son’s copter. Red wire not attached to solder joint. Is ther a reference of the circuitry so I know where to reconnect the wire? Thanks
Hi Syma Freak,
I have the same problem that the red wire going to the motor was broken off the solder joint.
Please can you send me the email that you sent to Robert to help him to fix this problem.
Thank you,
sviet
Hey guys anyone having problems with their radio? I can’t seem to get mine going. Brand new never crashed or anything
@edgar5bss As mentioned pn other comments try the forum-binding syma
Try tuning the copter on first. Then the radio. run the throttle open full then back x2. Light should stop and copter should fly. If not turn radio off and start over. Took me a minute to figure it out too.
Hi,
Excuse my apparent ignorance (I’m still farely new top RC helicopters and new to electronics) but when you swap the tail rotor for the suggested Picooz tail blades, instead of turning the tail part upside down, which in my opinion makes it look rather ugly, could you not just swap the wires on the tail motor? Maybe cut them, switch and solder them back together again or switch the leads on the board, and keep the tail motor the right way up?
I know not everybody has a soldering iron but is that not an idea or am I being stupid?
@Ryan you are not ignorant but rather asking a good question-the reason to turn upside down is that the Picooz tail blade is somewhat bigger and a different shape-the problem happens is that it will crate a turbulence with the main rotors and cause the heli to drop and crash-if also you see that the Picooz tail blade is just to close to main rotors-I hope that helps-Never be scared to post-you can never be stupid either -as maybe you just answered a question others were uncomfortable to post-Take care SF
I was actually wondering the same thing, just in reverse if I need to for the larger one for my huey project.
thanks for that!
Hi there,
I just did exactly that. Cut the wires under the hood, switched them, soldered them back together and finished with a coat of liquid electrical tape. Not only dose this look better, but it works better as well. Much faster than just using the picooz blades and turing the motor upside down. I have had no problems with turbulance or anything of the sort. I also removed all the junk on the tail boom(struts and fins). I don’t know if that makes the difference or not. I also found the tail rotor more prone to damage during hard landings when it was upside down.
Hi guys,
I agree the Picooz tail rotor blade works fine. I did a little research and after that I upgraded my own Syma S107 with a bigger tailmotor. Why? Cause the original motor has not enough power to get the s107 to some serious speeds.
If you’d like to see what I did, please visit: http://symas107modifications.blogspot.com/
Greets.
I saw that- my google account’s screwded up, and I can’t comment, though. Great little project!
I was just thinking that it’d be best to bend the tailboom like you did. Although, I was thinking that if you did it the opposit way, (by about half of the angle it flies at) you would have a very slow reaction time (foreward– very fast reverse time) and very slow acceleration before really going, but would give the tail much more lift to produce a much higher angle for the main rotors, giving it a higher top speed.
I guess it’s preference, though, between accerleration and top speed. Like porsche vs cammaro.
Hi,
Nice work. You don’t know what motor that is or what it came out of do you? Do you notice any reduced battery time with the bigger tail motor? I’m thinking about a tail motor swap myself
Hi guys, I’ve had my blue Syma S107 for two weeks now and I’ve crashed it a few time so far, nothing too bad, but two things started happening. First, the heli (specially the tail) is vibrating a little too much I think and therefore the hovering is not as steady as in the beginning. Second, the forward flight is half the speed it used to be 2 weeks ago, it even comes to almost a complete stop sometimes even if I have the joystick in teh controler all the way forward; and going backwards is also slow too. I already checked the back rotor, I don´t see it sliping or anything like that. I even saw someone cutting part of the back blade near the rotor to make lighter back there. What would you recommend doing? Thanks in advance…
Sounds like a case of damaged rotors to me- out of balance, making it shake, damage to the tail rotor or motor making it loose lift on the rear when moving. Could also easilly be a loose connection to the tail (or even drive) motor.
But, being that you checked the tail, sounds more like the tail motor or a drive motor.
I personally wouldn’t cut the rotor to make it lighter- that would do almost nothing, and would just compromise the rotor. I’ve seen weights added to the front, the classic tail rotor flipping + special rotor upgrade, but not that one.
Hi I am very interested in the forward/reverse variable resister mod. My joystick has to be moved all the way forward to move the
heli forward and kinda jerks sometimes on and off…. or maybe my rear tail motor is going bad? Only 2 days old but anything is possible I guess. Thanks in advance…
hola gente muy buena la pagina… les comento que me compre en SYMA s107 , pero lo consegui en francia , por lo cual el manual de usuario me vino en frances. entonces mi pedido en por si me pueden facilitar el manual en Ingles almenos para aprender a manejarlo. muchas gracias desde ya.
Hi guys, this is such cool post. I’m about to purchase my first Syma S107 or S107G at amazon.com, as I see it described there. Any general suggestions? Also, thinking ahead do you think I should get any spare parts, and which parts would those be? Thanks for your advice!
@Marcelo-I would not start worrying about parts yet,reason you will end up buying another and used smashed one for spares-they are addictive birds!!
Thank you Syma Freak. You are right. I’ve had my S107 in blue for 2 weeks now and I love it. I’m already thinking about getting a new one in the near future.
What the whoo??
What kind of video is this of battery hacking. Looks like me as somone who is trying to get attention and
doesnt know what the whooo they are doing. Plug and play, no voice instruction, no instruction at all.
Just some zero pushing a battery in and out. Clean it up guys. Just making a big fool of yourself when you
put a video like that on here. Try kiddie land for you escapades ok?
@Lan I found that video on Youtube that just shows what people do with their Syma S107 for fun-This blog is for the love of the Syma S107-Why do you not show us a video you can do on battery hacking for the Syma,will gladly post it on my blog- if this blog or video offends you in anyway it is produced I am sorry. Have a great flying day SF
Hey great tips here. I started moddong my blue s107 flat black paint, I removed the rear support bars and all the wings resulted in 2x as fast with about 1/3 more battery life. Also I tried the rear tail rotor mod with a havok blade. I think the pitch angle of the blades was a bit too much tho
@ Jeremy sounds cool-might put a post up on remodeling the Syma 107- feel free to send me some photos to post
If you don’t wish to invert the tail motor, remove the canopy and swap the two wires that feed the tail motor. This will cause the motor to run in the opposite direction and make the new tail rotor work.
@Mark, That is nifty, will try, am always learning, keep those comments going helps us all with more fun with our Syma S107G
SALUDOS MUY BUENA PAGINA GRACIAS A TODOS QUISERA SABER SI TIENEN EL MANUAL DE USUARIO DE ESTE HELICOPTERO SOY NUEVO EN ESTO Y TAMBIEN SIME PODRIAS DAR UNOS TRUQUILLOS GRACIAS

I got my S107 flying really well after I got over the fear of crashing it, but the throttle really sucks, and I knew I should
do your throttle mod…….but now they changed the setup on them!
I could slip the spring and make it go inside the silver box, but if it binds up, It would not be a good thing. HELP ???
What is the little white turn thing pointing at 600 ?????
@Mike,you are a machine dude,just got your Syma and into mods already!! As I am the Syma Freak have 11 of them,some really smashed but good for spares,others still cranking it no problems- As mentioned on page review I have now bought a few from RcFever without remote or USB cable for $17 a pop-they were not fakes so binded ok with old remote-hey that remote you have,send me photo of the front,looks heaps different to ones I have-better still join my forum and start a thread-then your videos will show-awesome buddy,enjoy
got it-really appreciate your effort to help people like me just entering into the remote helicopter world-Thank you Syma Freak-guess you really are mad,lol
@ Charlie-you got that right-totally mad on helicopters-good sh– tho-makes me smile-how about you? keep flying the Syma S107,and welcome to craziness-Take care:SF
