yep....the flybar pins were broken....I have since replaced that part and the s107 flew again....until I went on to 4 channel and then 6 channel...Now the s107 has been sold. Thanks for the post....you were spot on with your observation.

Hey Sizzlemywizzlevdeos, thanks for the the input....the problem was the two tiny support posts that hold the top rotor to the main shaft broke off....I have since repaired the s107 and it's still flew great and then I sold all my syma helis the s107, s006, the s031g, the 9100, and the 9104. I got my money's worth from them all. ....I no longer fly 3.5 channels but I have to admit...the s107 was a really good learning tool.

Thanks noah for the reply...I wish it had been something as simple as the carpet....but it wasn't... it was a broken flybar...I knew nothing about that at the time of making this video.....I have since moved on...thanks again...and fly like an eagle....peace.

Greetings Sir and thanks for commenting on my former problem......I fixed the s107 and she is hopefully making some kid happy as I donated it to a Childrens shelter....The problem was the flybar connects broke and once it was replaced, it fly great. I have move on the larger birds now but still appreciate your interest in helping me solve the problem. BTW...have you checked out the Syma f106....it's a four channel.

Thanks for the suggestion Mr. Patrick....but the problem was actually the flybar...It became disconnected from the main shaft...I fixed it and sold it along with all my 3 channel helis.....

I love youtube for just this very thing...Hey Popeyevallshipd....thanks for the post...but I fixed that bird over a year ago...but I love your points because it could help me or some of my viewers with their birds problems as well. The problem with my S107 was the flybar pins broke off. thats' why the blade was so floppy. I have fixed it with the help of all my viewers like you. I now fly a Trex 600 and love it. Thanks again....

Wow...I had all but forgotten I posted this video....thanks for the post....The problem was the flybar pins broke off and that's why the top rotor was so floppy. I fixed it and it fly fine. I have a trex 600 now....and that's a whole new world.

@toadman602 - LOL.....you said small balls.........Just kidding guy....I did fix the copter and you are absolutely right...I ended up getting a replacement blade grip....a couple in fact...because I see that as a weak point in the copter design.

Thanks Alan for the help....but the problem was the flybar pins broke off and that's why the top rotor was so floppy. I fixed it and it flies fine. I have a trex 600 now....and that's a whole new world

Just after 2 days of purchasing my Syma S107g it lost its stability. As soon as it fly up it become unstable. Please help , how to troubleshoot this issue.

Yes...I did....also I tried something new....I put a piece of fairly stif plastic on all the blades and I was amazes at the even greater stability. I put a bigger battery got about 10 min flight.....I have since sold it and replace with a MQX.....thanks for posting.

A flybar is the weighted bar on top of the top rotor. It allows helicopters to fly with stability. Hope that helps.

Hey MW2Master36, I wish it was that simple but the problem was the flybar pins were broken off. I fixed it and the heli flew fine....I have long since moved on to bigger helis now....thanks for the post.

It took me about a half hour to replace the bad gear, there is a lot of parts to remove and then the gear is hard to get out, but I found a video on you tube that showed how to do it. The only thing I did different was I used one of the short little gear posts (the gear set came with two rep[lace ment short gear posts) to push the old post and gear out with, this worked better then grabbing the old gear with a set of needle nose and twisting it back and forth to get it off. (like in the video)

Thanks skaterboy2502 for you suggestion. Actually, it was the flybar. I bought a new one and it flew fine once the damaged flybar was replaced. I have sinced sold all my 3 channel helis and graduated to 4 channels and now I am flying a trex 550 with training skids and a teacher of course..

No worries bergi85....I fixed the copter and moved on to bigger and deadlier birds....thanks for the look out...peace.

Thanks for posting....but to clear things up.....the flybar broke from the main shaft....that was the problem....I fixed it and flew like new and I sold it with about six other s107s.....now flying HK500.

@Hoarhound1 - Wow....15 copters.....why so many....but I did take your advice and I ordered two more S107s and a few extra parts.....I also ordered a 9100 and 9104.....before I break a more expensive model....I am gonna cut my teeth on these......thanks for the help.....

The gear sets were cheap (only 2.00). I am now glad I ordered them with the 107. I have been thinking about getting an mcpx next, skipping the four channel and going right to colective pitch. I know it will be hard and i will probably crach a lot to begin with, but I am thinking the mcpx is so light, it will withstand the abuse a lot better then a bigger helicopter would, plus I can learn to hover it and do the simpler training in my house or back yard, rather then having to go somewere to fly.

Hey thanks for commenting bekosway....but I have to admit...I am a little confused by the post....what are you telling me?.....but just so you will know....the problem was the swashplate was broken.....it has been fix and is still flying.

@ Colinbrown303, thanks for the suggestion....the problem was their are two little pins that hold the top rotor to the main shaft...I replace the entire rotor assemble and the problem was fixed.....

Thanks ThtiherSark984 for your post. The problem with the heli was actually the flybar connect pins. They broke off during a hard crash I guess. Anyway, I fixed the bird and it flew fine. I am now flying a Trex 600. Now that is a scary blast. Again thanks for the tip....

You should try to buy the S107G which the G stands for Gyro. The Gyro will actually balance the heli out. You have to manually adjust the Normal S107. Hope this helps. Oh and I got it on Amazon brand new from Syma. Just hit me up if you have any questions.

@Pokedudegio0 - Hey thanks for the post Pokedudegio0.....It was'nt the carpet..it was the flybar connectors to the main shaft that broke during one of my many crashes....I had to buy another S107 to see the problem....I have made some mods (upgraded battery, wider rotors for main and tail). ...I fixed it and it flies great....I have move on to a four channel single rotor now and I am having a ball....Next is a T-rex 450.

@MrKwanlee - You know MrKwanlee.....I thought it was the connect buckles too....but both were connected at the time of that video.....I order anothe s107 and I am hoping that I will be able to see how that unit is connected but I think the problem is the main shaft has broken free from the to rotor somehow because I see two points on the shaft where it seems something was connected...I will try to get a better close up....thanks for the advice.

The problem is one of your gears are not spinning well which slows the bottom propeller and gives more speed to the propeller on the top, try checking your chip and see if any cable is disconnect or check the gears if both of them are spinning.

okay this is the easy way 2 do it. being that most of u are new 2 this hobby.... go 2 the store buy a new one than take the one that dont work replace it in the box and return 2 the store keep the one that does best way 2 fix this cuz if u can't figure this out now taking apart n putt back you might as well just throw this in the trash

I bought the bigger model (s031) and had the same issue and couldn't figure out why until I noticed that one of the connectors was still attached to the bar and the other was not connected to anything. The other had broken clean off. (I took a couple hard crashes learning to fly it.) My church had an "inexpensive RC helicopter" on their wish list for VBS. It's turned into a little more expensive since I had to order replacement parts. ;-D I also got the s107 which is a lot easier to fly.

You're right it was those two little pins....I fixed it about six months ago and sold all my 3 channel birds.

@bunybuns - hey thanks for the info....but I did fix it....it was actually the flybar...I have sold it along with all my 3.5 channel helis and now flying 4 channels. but ya gotta love the little indoor copters......thanks again....

Thank Alan...You are 100% right....I figured it out and got it flying...I have sinced moved on but thanks for the input.....

I have one for my kids and it does the exact same thing.....I'm not too tech savvy so can you show how you fixed it or what should I do

@riotechdeck1 - No....I learned that there are two little knobs that keeps the top rotor secure. I have purchased the required parts and now I just need to put them on....Hey man thanks for the look out.....peace

@TheBeatSmith No I figured I'd wait until battery performance has been fuct on the 150mah. But did plan on the 240mah later, but that was to counter balance the 6020 tail boom i was going to put on it which is slightly heavier, with the bigger motor. When I removed the balance bar thing that destroys 99% of s107s, its just a flattened pied of metal on the shaft. I've considered using a dremmel and making a tiny indentation if this happens again. but yea, cuz had the warranty, loving my s107!

Hey BeatSmith, take a closer look at your upper rotorhead. notice how it pivots (or used to) on a set of two stationary pins. If the pins are there, that wobbling is normal. It uses the counter weighted flybar to stabilize the upper rotors and keep them parallel with the ground Make sure the rotor head is wiggling only side to side NOT up and down, otherwise this will create an elliptical (egg shaped) oscillation that causes the blades to produce more lift on one side of the heli than the other, tipping the craft to the side of less lift. Best of luck!

Don't worry...Be Happy...fix it and get back to fyling...fun in these coptesr is repairing them.

Great you have fixed it--we are all crazy nutters on the forum,you should join..you are welcome to put a link on your video to the forum- have you joined yet? please do and post your video and how you fixed it-helps a lot of people...

I love this little bird....I fixed it and it still flying over a year later...But if you want to progress to larger birds you will be a 4 channel. Syma offers the f109 to give you some idea of what it's like to fly hobby grade helis....I now fly the trex 600...it's scary as hell but man what a rush.....

Hey Thanks mbegick....man I just could not figure that out....I eventurally just bought another on.....I have move up the a fun copter and I just bought a HK600....but it all started with this little baby....I still love flying it....By the way, have you seen the new four channel version of s107.....????

Main problem is need flat surface and don't start fan . The helicopter need stable air for perfect take of. Then after no effect you change some spare parts!

Look inside where the gears are, one might not be touching the others. I had the same prob, used a pin to push the gear back down and it work

Thanks for the info....But no it was not the dogbone linkage...it was the flybar....it broke away from the main shaft.....

The top blades have detached from the shaft. You can see the plastic stuck on the shaft and the blades come off

@TheBeatSmith I've made tons of changes and mods, and plan far more. I'm waiting on 240mah batterys because I'm planning on using a compUSA heli that doesn't interfere as a 4th channel, and adding two things in this order. 1. RC grenade launcher or mock white phosphorusattack, and 2nd, im going to use the trim of xtraRC to cause a small bar to transfer weight to make it roll, I've pushed these things to thier limits and love outdoor night fly.Look up syma s107 streamlined night

Hey man i had this same problem... i just used a shoe box for the take off. the problem is the carpet getting caught on the landing gear.

LOL....Nah.....I fixed and it flew....I sold it along with all my syma copters......thanks for the comment.

@Bradock27DBZ - Hey thanks for your inquiry......To answer your qustion....yes...I did fix it with the help of these great answer......Now the way to fix the problem is really quite simple....look at the top rotor....if the fly bar is not attached.....just buy a new one for around $2.00 bucks.......buy a couple cause you will most likey break it again.....Good Luck.....Happy flying....

C'mon man....be cool....I welcome all positive comments to help. I am sure you will agree bullying helps nothing or no one. Peace.

Still flying your fixed S107 ? - I just got an s108 and its bloody funky as hell.

@fastblackbird - Man I wish that were so.....I actually went to FunCopter while I built the HK600.....Thats what I fly now....but to be real....The damn thing scared the hell out me at first....It's big, fast and loud as hell. I put stabilization on it to tame it down....I can fly backwards and inverted forward and backwards with the best of them but no real 3d yet.......funnny thing is the bigger the heli the easier tthey are to fly......I am building a F9F jet now.......see ya in the skies.

You are right, it wasn't the connectors or (dogbones). Can you guess what it was?

nah...no wing repair kit....I paid 20 buck for the bird on ebay.....I did fix it though....sold it along with all my 3.5 and 4 channel helis and now fly my trex 600......no crashes yet.....I come a long way in a relatively short period of time....next......I'm getting an Extreme Flight 540......check'em out....they are awesome......thanks for the help anyways.....peace......and get flying....

it could be that the screws below the propeller are a bit too loose so the thing just slips when they are spinning.

@ colinbrown303 -I have since sold all of my syma copters and bought a funcopter.... and Trex 500....they are a real blast....and best of all no crashes......not even one.....but I have to admit....no real 3D either....but I am fine with that for now....I am just doing Aerial Video now for may clients.....and having a ball.......again...thanks for the info.

In this case it was not the main shaft....it was the connects for the flybar....but it's all good.....it fixed it and sold it....now I on to breaking more expensive helis....LOL....thanks for input....peace

There are 2 dogbone connectors that attach the blades to the bar on top. You can get a repair kit on Amazon.com for less than $10.00. Helpful videos on KZfaq will also show how to repair it.

you are supposed to accelerate it fast. the top blade is supposed to be a little lose.one last thing, you know the bottom knob on the controller, make sure it is in the middle

It's because the battery is almost died or drd just charge it and it be ready to go the battery lasts like a bit so yeah

that shit was straight comedy lol i was rollin the seconded motorup, lol ''wat happen'ed'' ''shit falls again mon'' LMFAO oh shit i was lol wen i was typing this

The syma s107 of course. If you have some flying time under your belt then I would look at the syma f106...its a four channel. That means as you progress to bigger copters the radio controls are the same until you go to a six channel then its a whole new ball game because of inverted flight. But the s107 and f106 are pretty tough and can take a few crashes but in the end, they all need repair at some point. Hope that helps.

I guess you have the problem resolved by now? I just replaced one of the gears, mine sounded noisyer then it did, and it went a little to noe side. In my case the one small gear that was between the motor (not the gear on the motor or the gear on the main shaft) and the main shaft, has some ground off teeth on the smaller (tiny) top part of the gear. I had luckly ordered aan extra gear set and an extra set of blades when I ordered my Syma 107. Good luck and let me know what was wrong with yours?

lol....fixed it for $2.00 and save $18.....thanks for the comment.

you are absolutely right....that indeed was the problem....

Just make sure if it's fully charged. I had that same problem and later I discovered the battery was not fully charged

LOL...good try Jared but that's not the problem...this is a 3 channel helicopter, so the tail rotor will not spin until the elevator is pushed forward or backwards. The actual problem was the connection knobs on the fly bar were broken and thusly not connected to the main shaft. That caused the fly bar was out of balance and that's why the heli leaned to the side and would not fly....Rest assured though...I fixed the heli and it stills flies but I am now flying 6 channels helis.

@Pokedudegio0 - By now your bird should be all dried out and flying again;;;that is unless you broke something in the crash....I hope that did not happen but if it did....do not try and fix it....just buy another and keep on flying.....peace...and fly on brother....

No...it was the flybar pins that broke when the I didn't release the throttle during a crash. It is fix now.

The broken connect pins on the flybar were replaced and the bird still flies....I have since moved on to bigger and better birds.

The axis of the upper propeller blades which fix them to their rotary is broken ... that is why they are just hanged by the balance control shafts.

I have that same helicopter, Mine starts(sometimes) and when that happens it goes off ground for about 2-inches, then falls and doesn't function, Can someone help me out

Look at the top blade just inside the flybar.....there are two little knobs that connect to the flybar to the main shaft. Most often they were broken after a crash.. You will have to buy a full repair kit to fix it....it's costs about $5 on amazon or Amainhobbiesdotcom. But to be honest, it may not be worth fixing since the s107 has come down in price $15 -$20 bucks....mind was $30. On the other hand...fixing it will help you understand what makes these birds fly. good luck.

@TheBeatSmith yes it flies now but mine is called the alloy structure

C'mon Rocketman.....even a rocket takes its time getting up to speed...right.....But I just kidding...I put that video up over a year ago and I have long since fixed my beloved s107...It was the flybar pins that failed. I bought a repair kit and flew fine. I have sold all my 3.5 channel helis, graduated from 4 channels and small 6 channels and now i am flying a Trex 600 for aerial video. But thanks for the advice...now go fly that heli....people

Sorry Mate...not quite sure what you are suggesting...but the s107 has been fixed.

@mexicanmachin92 - I don't understand your point....are you saying the copter is called "The Alloy Structure?"

Greetings futachamp...I would suggest you make a video that demonstrates the problem. With all the help from the youtube RC community, I was able to get my s107 back in the air.

@PyR0Star - Hey thanks PyR0Star. I just wondering how the top rotor is connected to the main shaft....By the way...have the tried to upgrade the battery or make any mods?

No...it was the flybar pins they broke when the I didn't release the throttle during a crash. It is fix now.

I havethe same issue, almost. but I noticed the shaft was bent, since the heli goes backwards. It will not lift so the shaft might be bent on yours.

No, that was not the problem.....the flybar was disconnected from the main shaft. Thanks anyway.

its simple... i replace the broken plastic shaft with steel shaft to let it stay in place i drilled a hole through the drive shaft

The tail rotor isn't suppose to be on unless you are going forward or backward

if you look inside it and the small circuit bored is green then unlucky, you have a counterfeit model. If its red then you have the correct model just faulty :( goodluck ! :D

Your INNER SHAFT is broke. That's why the top rotor is loose and the copter tips.

Try change the gear or tighten the screw at the second rotor that connect the blade with the main shaft.

look at :37. when he has the throttle down, the rear motor isn't spinning on the tail. that is problem. its not lifting because it isn't moving

When you say pair the receiver. Do you mean bind the receiver or do you mean repair the receiver...either way I would do a precheck....I assume the battery is fully charged and the lights work....right? are the batteries in the transmitter seated the right way and are they fully charge. It could be a bad board as well....It's hard to tell without seeing the problem.

if your having that problem you might want to check out this video "Syma S107G main shaft repair on the Top Rotor."

If I have any problems with a seller eBay has always made it right or pay pal ,my only problem with many orders is a couple didn't show ,so they gave me a refund ,I have never lost a dime with ebay

So how did you fix it?

mine did the same thing and seemed loose after i hit the celiing. Thankfully I am getting a refund and gettin a nwe one. My only guess is that the bar that holds the props and gears came loose. does your main rotor move up and down??? i can fly it in circles while trying to hover then it suddenly crashs. crap shoot with these buggas, fun as hell tho

The bird has been fixed and flying nicely still after a year.. Its was a bad flybar. By the way....what are clips?

OK....I'll bite...why does the carpet color matter?.....but to answer your question, the carpet came with the house......and because it's a 3.5 channel infra-red.....It can't be flown outside as well as inside.....

Actually I only needed a new flybar....thanks for commenting...

It's a 3 channel heil....the tail rotor only spins to go forward or backward. It will not spin while hovering or swinging the tail left or right?

sorry for being a bit late to the party, but have you checked your trim?

one the top propellers are supposed to be that way two try taking it off the carpet three check the gears

in mittle of the top blades what balances them is loose!

so the problem is it is on the carpet you need to take it off on a table or tile floor just not carpet cause the landing gear gets stuck in the carpet witch causes it to flip to the side i have had like 30 of these thigs

KZfaq RCers are great....thanks again guys....
