Might help if we knew what type it was Eg coaxial, fixed pitch etc.
I'm going to assume its coaxial. I had one that wouldn't take off, turned out to be a broken rod between the upper and lower blades.

Was the problem after you crashed it?

Maybe it doesn't spin as hard? (Stuffed batteries ) I got some cheap rechargables off eBay they lasted about half a dozen recharges before being stuffed. I now only get rechargables locally.

Problems that effect rc helicopter lift.

1. Not enough head speed and/or collective pitch.

2. Spinning may be due to the gyro not holding the tail with enough pitch on the tail blades, if no tail rotor and counter rotating blades, problems with the motors that control each set of blades. The gyro needs adjusting. Or see the first note.

Hope this helps

thanks for the replies

just had a closer look at the helicopter and one of the nylon gears are stripped

the chopper I have is a EV01 Gyro RC Helicopter

is there anywhere I can by a new nylon gear?

cheers

Buy a new one and keep that one for spares. Its $35. I reckon a gear would be $10 even if you found one.
