Syma S107 Battery Mods By Dale
Syma S107 Battery Mods-Update
I have a great Syma S107 Freak like me-I would like to introduce Dale Scribner. He has emailed me some Syma S107 Battery mods with photos that I feel is really worth considering to get more fly time from your Syma S107G.
I know he will be online to help with any problems you might have organizing your Syma S107 battery mod, so contact me here and will get his help for you, however just follow his steps and photos that really explain all-He loves his Syma's and gets the most out of them. So below is his email and advice with photos to change the battery power of your Syma S107.
Email From Dale Syma S107 Battery Mod:
I purchased the connectors, and the E-flite 3.7 150 Mah 12c batteries at the hobby store. Remove the nose, 2 screws. Unsolder the syma battery and remove it. Remove the weight from the nose also. Feed the connector up through the slots and solder the red on the left and the black on the right, same as original. Replace the nose.
If you find Amazon out of batteries try Hobbyking they are cheaper and quality not to bad, you have to get your own velcro. Connectors also ok but you have to cut end of wire not required-doable!The connectors from Amazon are better,they sell out fast.
Apply the supplied velcro to the bottom of the nose, the loop side. The velcro comes with the batteries. Apply the hook side to the battery. Charge the battery and plug it in, press it to the velcro so the the black end of the battery is even with the back of the nose shell. Note your polarity, always.
The S107 will be balanced for flight. I kinda think the batteries look like armaments under the nose. No more waiting to fly, just change batteries and go for it.
I purchased a Parkzone battery charger or a single battery. They make a bigger one that will charge 4 batteries. I am going to purchase that next. The single battery charger uses 4 AA batteries and you don't get to many charges. Also, when you apply the velcro to the battery, as I show, it fits to tight into the charger. I took my Dremal and opened the back of the slot until the battery fit as it should.
Thank you Dale-Photos below in order Dale sent me:

Well there you go-great mod and photos from Dale Scribner. Guys it is important to thank great heli freaks like Dale for sending me this information- Feel free to leave comments, you might have also done some battery modifications on your own Syma S107, share with us below- or any mods done on your Syma Helicopters- Above all enjoy your Syma S107
Disclamer
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-
Dale has just sent me another mad mod on his Syma S107 to land in water-must be done not in bright sunlight as infra red remote-Pretty cool idea-photo then video below:You need to do Dale's battery mod above first-all for power and center of gravity.
Up Date Email From Dale January 1st
The pontoons were cut from Styrofoam, sealed with water base paint, then sprayed with water repellant. I tried several versions before I got it right.
I wasn't flying in the sun. There are large trees behind the pool and I waited until the sun went behind them before flying. One time I was trying this and some rays came through the trees and the heli dropped like a rock into the pool. The heli would spend the night in the oven on 110 degrees and was fine the next day. I did not bake the batteries, just dried them off with a paper towel and blew out the connector. I did use the battery mods listed on syma107 site as we needed the extra power to break the water tension. I had to try this quite a few times before I got it right. With the pontoons adding extra weight, it was marginal at best. I used dental floss to tie the pontoons on.
Thank you,
Dale

Hi, I also have two S107Gs.
Am I right in saying that the PCB on these is matched to the controller?
If so is there a workaround because having one controller for n helis where n is enough to make a flying message display would be seriously cool!
Also am in the middle of a battery mod here, using eFlite 200mAh 3,7V 25C pack as these aren’t particularly expensive here and the model shop have them.
The Arduino folks like these too as the TX codes can indeed be generated so some autonomous flights are possible.
Great mods all you Syma freaks! I found a better, if a little more difficult, battery mod – http://www.rcgroups.com/forums/showpost.php?p=20016051&postcount=9735 . It basically does Dales mod but keeps the battery inside the canopy. To go with that mod there’s also a link in that post on how to mod your canopy to make it quick remove. BTW, I have not done either of these 2 mods as I have so home repairs the wife is yelling at me about.
I’ve also seen a 350mAh battery looks very interesting. With all the lightening being done, I think the lift capacity is there.
Thanks for all the great ideas guys, my S107 is a screamer now. My friend has a bone stock S107 and I can’t get over the difference.

Will this charger work? How do I know which charger to match with a battery?
This charger will not work with the battery you want to charge..This one will(click here)
I wanted to get the batteries from HobbyKing (http://www.hobbyking.com/hobbyking/store/__10980__Turnigy_160mAh_1S_30C_Eflite_Minium_compatible_.html)
If you look at the specs, these are smaller, and lighter than the e-flite ones you linked on amazon. Can someone confirm this?
Are the Turnigy batteries any good? They are a much better price
Also, could someone please recommend a good charger from HobbyKing for these batteries? I want to order everything I need for the modification in one order, to save on shipping…
Thanks!
I buy all my batteries from Hobbyking for my planes helis,quads,they are cheap and I have had no problems with any yet
Thanks, Dale! Just did four of these and it worked out fine. The whole idea of *soldering* to change batteries is bogus. Where else do you do that? Part#s I used- Connectors: parkzone PKZ3052 Battery Connector/Wire Cessna 210 Velcro: parkzone PKZ1039 Hook and Loop Set (5) Ultra Micros.
Mostly I’ve gone on to 4-channel (Blade MCX2s are great, and highly recommended for a next step after the S107s)
But I still like having S107s around. I still like to fly them sometimes. And they’re great for turning on new flyers. So stable and simple. And if they like flying they can get their own S107 for about $20 (MCX2 RTF is $120).

I did this battery mod and hooked everything up. After i was done it wouldn’t fly up as if it didn’t have enough power. Anybody know what what the problem may be?
Did you take original weight out of canopy? Sounds like center of gravity a problem,also move battery forward a bit on velcro
Yes I did remove the weight in the canopy. And I tried moving the battery forward too but that didn’t help. If I put on a completely charged battery, for the first few seconds it will fly ok. Then it comes down till it only flies about 2 or 3 inches above the ground. It seams like it is too heavy.
i got a question for you Syma freaks. I bought the upgraded battery from Amazon (240 Mpz) and the first 4 flights were freaking awesome; longer flights, way faster and more power. Now im four days into the mod and it doesn’t matter how i charge it either from a wall charger, or the controller I cannot get it to fly more than a foot off the ground. Please help me out!!! P.S. I soldiered the new battery into the helicopter…. Help m,e out please
I’m having a similar experience – I was doing some heavy mods on my Syma (cut the front off and lightly epoxied the circuit board for a camera and a tiny lens. I have the new battery underneath. The first time I tested it my little copter zipped up to the ceiling, bounced off and landed on the floor.
I decided to wait until my rig was a little heavier to start testing again, but now that its all back together, it won’t fly. I thought there must be more weight, even though I technically shed a lot of weight overall, so I took the camera and body off. It still won’t fly, and its starting to sputter now. The motors spin up, it stutters and spins down and then spins up real fast again. I looked at my battery connections and they’re all good. So… I’m a bit worried I burned something out.
The original battery is about 3.5v and 180mAh, and the replacement is 3.7v … so I don’t think that would be risky to the circuitry at all. Wonder if I got a bad battery that isn’t hold a charge correctly.
I have purchased at least 100 or so of these syma s107 and that Helizone Firebirds and have customised everyone I have found I like to squeeze 2 factory ds batteries in them to give the nose that extra weight Plus I add a lead sinker and they really hall ass Shave a couple that i’ve put a bigger tail motor on however I can’t seem to just buy the motor without the bird also have almost replaced all the R5 s with the R3 circut boards if I knew how to send pics I think you guys would enjoy some of these birds.
I used an Eflite 200mAh, 3.7V 25C and it works fine.
How do you keep the eflite battery from becoming too discharged and unusable?
Please read info- Do not over charge let battery cool down before recharging
I have a li-ion/li-po smart charger from Tenergy I just bought to charge up other toys. I’m wondering how I might use it to charge the Syma S-107-G. I’m guessing it would be much better for the battery to use it instead of just plugging it into a computer. I’m guessing I can just cut off the USB end and put on the connector it uses, right? Then… if I buy a bigger battery to install inside the copter (like the first battery mod) would I still need to use the original battery’s PCB, or not since I’d be charging with a smart charger? Any advice? I just would like to be able to fly for at least 20-30 min, then charge it using the smart charger for till fully charged again.
Thanks for the info Syma Freak. I Just did a similar Mod of my own using a battery that was 3.7 V and 350 mAh. I cut the stock battery out and replaced it with the newer one which was also bigger in size. However being slightly nose heavy made it even faster in my opinion. I was very pleased with the
results especially the flight time! Normally I can fly my copter for about 5-7 mins tops using the stick battery. I was able to fly my copter for 35 mins after I installed the new battery! The down side is that it takes a bit longer to charge (about 1.5 hours) but definitely worth it. Just thought I would share my two bits with everyone.
Thanks fir the great info.

Can you charge your 350 mAh battery with the usb cable after you replaced the 150mAh? I saw that they have a 700mAh but I dont know if I will be able to put it in the s107 and whether or not I will be able to charge it thru the usb cable
@Cranston know you need a different charger you can also buy a cheap usb cable to charge with,only does one battery at a time tho.
@Syma Freak: I did a bit of research and found out that the 350mAh 3.7V Lipo battery is 8g which adds 4g to the helicopter but I want to know if it’s worth doing it as adding more weight means I have to use more power=less time. I saw a lot of web talked about the mod with the 240mAh battery but then why no web shows the upgrade with the 300 or 350mAh then? Having multiple batteries to change after each flight is nice but I still want to have an upgrade built in the helicopter as the original and be able to charge it thru the provided usb cable. DOn’t know if it’s possible to put the 350mAh battery in or not
Can you charge with the usb cord it came with ?
Hello,
What would happen is I replaced the stock battery for the S107 with a 3.7V 350mAh battery?
Thank you,
Bijay
@Beej Dales battery mod means you do not have to wait between charges to fly your Syma S107G,a little longer flying time but more important is the offer to fly more and change the center of gravity for the heli- hope that answers your question
Hi Guys,
Well I am totally bitten by the Syma 107g bug, ordered mine off amazon today and have watched every video about it available! Plus your site is very informative, thanks!
@Dave glad you like the blog and thank you for comment
hi just wondering about dales post just then. he mentions using batteries (hyperion) that are better than the e-flite. would he use the same method to attatch those and if so what is the full battery name and price comparison
also i was looking at them online and the 12C batteries are about 10x the price in comparison to the 10C batteries and i was wondering what is the difference in the 2
Hi, I like your page, I really need to setup something like this for all my micro heli experiments and mods.
I like the simplicity of the Velcro attachment method, in my youtube channel I did this mod a while back (before I had the 1S charger in these photos…
I took the LiPo over charge protection PCB off the stock cell and attached my socket to the Lipo terminals on the little PCB, this allowed me to charge these cells from the stock charger safely.
I am currently working on a google sketchup model to be 3D printed that will hold the cell and the connector so that you can just plug it in rather than having the plug it in then velcro it in place or modify the charger to allow for the LiPo velcro.
My first print has not come out as well as expected and I will have to redesign it, as for now i don’t have a page like this (or time to creat one due to moving house I will send you my progress so it can be shared with others.
I have also done the water landing mod, I could not take off either, I don’t think the S107 is powerfull enough to break water tension. the main difference in my mod and the one shown above is that I removed my skids and braces and replaced them with wide flat braces that ment the S107 was a lot lower than mounting the water flotas to the stock skids, while i could not take off i was able to taxi around the water without tipping over.
If the author of the water landing video accepts there will be a video responce to it of my water landing mod.
All the best and happy flying.
Dave.
djdavies83-Dale who sent me video will enjoy your feed back-good on u buddy-welcome here to my mad blog on the Syma S107
Has the video changed? I thought it flipped rather than taking off, ok whats the foam? I really want to take another look at this project now.
Hi Syma Freak, well i did the mod and it worked great for about 2 flights. It seems i unknowingly bought a Syma knock off. (this is my first experience with rc helicopters and know nothing)so i promptly burned out one of the main motors…..
With the help of a website that describes how to tell the difference between a real Syma versus a copy I now have a genuine Syma 107, have done the mod per your instructions (again), have flown 5 cycles and everything works great!
P.S. From one first timer to any other first timer that may read this, do your homework and get a real Syma! They fly way better than any copy and are a lot of fun! Thanks again Syma Freak
@Stephen Sak great the mod worked ok for you and thank you for posting-happy flying
I made this battery mod and it works great, got my connector from my local hobby shop, parkzone connector for $1.99. I perched my batteries (6) from Hobby King, Turnigy 160mah 1s 30c for $1.69 each. I made a charging cable($7.00)for my Thunder AC6 charger to balence charge 1-5 batteries at a time. I have pictures but i cant seem to post them.
@Joe m have you tried posting photos on the forum,easy to join-let me know
went to forum and tried to add a new topic, but was not able to add pictures, must be doing something wrong.
try this link to my photos

Can you use the eflight battery and charge the same way with USB connector? or do you need the special charger? USB is like 5v. so should be a solid charge
@tst you can not charge a eflite battery with the usb cord supplied with your Syma
As Syma freek said you can not use the stock charger, it is possible with a little modification…..
The reason for the stock USB charger not being safe is it has no over charge protection built in, this is the little PCB in the Stock liPo.
These 1S hobby cells do not have this PCB built into them, it is in the Stand-alone 1S charger.
When I did my first removeable “swapcell” mod I didn’t have a stand-alone 1S charger, rather than removing the cell from the main board I removed the cell from the little PCB that is connected to the main board and connected my socket to where the LiPo tabs used to be, this allowed me to charge these cells with the stock charger as the protection PCB is inplace between the hobby cell and the USB charger.
The only draw back with this method is that as you charge through the heli you can not charge a cell and fly a cell at the same time….
I got around this with the swapcell mod on my S026 and it’s charger, I cut the charge plug off the end of the charger wire, the “to heli” tabs of the little PCB from the stock cell was added to the charger cable, I then attched a socket to the “to cell” tabs and heat shrink over the moddified charger cable.
With this method I able able to safely charge any 1S liPo (while paying attention to the power out of the charger and the max charge rate of the cell in question) from my stock S026 charger as the overcharge protection is now integrated with the charger and not the heli or cell.
Everything in this comment is documented with photos in RcGroups website, Syma freek permitting I will be more than happy to see it here too.
All the best and happy flying, Dave.
@djdavies83 great feed back-any info to help us all is ok with me
had my 107g for about 9 minutes when i realized 1 hour charge to 6 minutes flight time wasnt going to cut it! I am SSSOOOOO doing this mod! Thanks so much for the info Dale! I really appreciate it! Stephen
@StephenSak let us know how you go with mod or any problems-is fairly simple to do
nice mod ! i try to do it! but what is the name of the micro connector? cause i try to find male and female connector for the battery….
thank’s

Hi Dale,
This might sound dumb – but why didn’t you simply place the Velcro onto the other side of the batteries so as not to need to modify the charger slot?
I’ve just ordered a couple of these Syma S107’s off Amazon and will probably follow your lead and do the battery mods for the same advantages you have found. It sounds common sense to go this route if we then move onto more serious micro’s like the Blade MSR or similar where these additional batteries and charger can be used to full advantage.
Great article – thanks’
Alan B.
@Alan B-I have sent your post to Dale-soon as he replies will post you-This mod was put together by Dale-he is the man to get the best info from-talk soon SF
@Alan B this is reply from Dale-the battery mod man
——————
The batteries have standoffs or tabs sticking out that get in the way when attaching to the heli. The tabs are for proper orientation when putting the battery in the charger so you can’t screw up I presume. I suppose you could cut the tabs off the battery, but I wouldn’t do that. It was easy to enlarge the charger slot..
Maybe if we reversed the Velcro, loop on the battery, it is pretty thin, then hook on the heli, that might work better and may not need to modify the slot. I may try that myself.
What’s great about this battery mod is you can move it forward or backwards for balance, fast forward, or neutral flight. I keep 4 batteries charged and handy so I can fly back to back. Hyperion makes a 160 mah 3.7 v that works better than the e-flight. I can tell the difference when using that battery, I only have one of those.
Dale
Hi Dale,
I know this is an old thread, but I just got a Syma 107G last week. Since I am already noticing a deterioration of the battery performance I started researching any info on battery mods. I really like your solution posted here, but I noticed this post you made about the Hyperion battery being better and I just wanted to know what charger is compatible with this battery. Thanks for all the great info!
Charlie
Great mod, I will try it. However you do not tell how many extra minutes you get?
BD
@bd not so much more time on flights around 5-8 mins but so easy to replace charged battery for more flights and to me some better power
