Brookstone cloud DSS copter will not stop spinning out of control and trim buttons will not fix it, what else is there that I can do to fix this problem.


many reasons for this, first tail rotor, then controller. but if the tail rotor in not working all it will do is spin just like the real ones I flew in the military.

Flutterbye fairy is not flying, the wings are spinning but not strong enough to lift her, she is completely charged


Mine is doing the same thing ! Look to see the upper rotors are flying even with each other mine are not ... One seems to be spinning higher . I'm thinking that's my issue

Bought Nano Hercules RC Helicopter. Flew it once and now lower rotor won't turn. Tried to call World Tech


I, too, have the Nano RC heli. Mine spins and spins faster if I try and take off.
Yours is a relatively easy fix. There are SCREWS under the rotor blades on the bottom. Tighten those.

Syma s107 hit a dangling string that got tied up instantly and seized the rotors. now lights up but blades don't spin when throttled. What can I do besides replace the helicopter?


I was flying my syma s800g and hit the ceiling fan chain. When I attempted to fly it would spin and fall over. The problem was I broke the two small plastic pins on the top rotor holder. Ordered a new top rotor and flies fine. Then on my s107 I flew into a door and the top rotor had zero spin although the motors worked. In that case the screw that sets the top rotor onto the middle shaft loosened resulting in no lift and also tilted and fell over. This was fixed by securing the set screw properly. So in both instances it was similar effects due to the top rotors not spinning in sync with lower blades.

S107g won't take off


I may be out of my area of expertise on this one, but it is possible to install the blades backward? That would cause the copter to try to go downward with the normal rotor rotation....just a friendly suggestion.

My helicopter won't take off, it just spins in circles clockwise until it falls over. It's a 4 channel RC helicopter with gyroscope.


This issue is the "Drive Gear Unit" It is the small gear just above the motors which is attached to the very large gear. You will have seen several posts indicating that sometimes this gear shifts and does not engage the larger gear. In my case I looked and say that it was indeed trying to engage the larger gear, however the gear is stripped (the teeth are nearly gone). The sound that you are hearing is the sound of the gear slipping against the Bigger gear. I have a UJ365 which is a newer model. To my disappointment I cannot find a "Drive Gear Unit" anywhere on line. The copter will not function without it. This issue is that it takes the lift of both rotors to lift the copter into the air. There are two motors (one for each rotor) and each motor has one of these drive gear units. Each of these attach to the larger gears which turn the rotors. The rotors each turn in the opposite direction. This is what keeps the copter from continually turning in one direction. When one of the "main Gear Units" becomes damaged it seems to have three noticeable effects. (1) There is a noise that is the gear grinding against the bigger gear. (2) Because many of the teeth are stripped the drive gear engages the bigger bear only some of the time, this causes the rotor to turn slower and in-turn causes there not to be enough lift from the rotors to lift the copter. And finally (3), someone noted that copter wants to spin in one direction. Understanding the above, you can now understand that if one of the rotors is not reaching its full potential to turn, it is also not reaching its full potential to counter act the other fully functioning rotor. Thus the fully functioning rotor is forcing the copter to spin in its direction and the malfunctioning rotor is not spinning fast enough to stop the spin.

So this is the answer to your questions, hopefully on the older models there will be parts available for you to replace it. The copter cannot work until the part is replaced.
