This is my first RC helicopter and I love it. I haven't had it long but am already having a problem after a very minor crash. Sure, there were hundreds of hard crashes but the minor one killed it.

 

All of the sudden, the tail rotor stopped spinning. At first it stopped going backwards, and was so slow going forward that it didnt move the chopper. Now its completely stopped. I searched the forums to see if there is a repair guide for it but I can't find one for the tail rotor in specific. I want to upgrade my helictoper, but I want to make sure I can do simple repairs on this one first.

 

Any suggestions? I pulled the casing off, and the black molding off the alum tail bar. I don't know where to go from here. The wires seem to be attached fine to the circuit board and the motor, but thats all i've gotten. Any help or direction would be appreciated.

If you take the tail rotor off does the motor spin? And are the wires connected to the circuit board AND to the motor, both?

Wires are connected to both. No the motor doesn't spin at all.

And the helicopter takes off? Just doesn't move anywhere? The gyro works too, right? So it can turn around?

Just started it up. Up and down are smooth. Left and right are smooth. Just no forward and backward.

What happens if you turn the tail rotor yourself while your trying to make it turn? Does it work if you push start it?

Doesn't work even with push starting it. I think i'll order another motor and just swap it out. I'm thinking the motor went bad. Could be from the crash or just burnt out.

Yeah, I haven't had any motor problems yet. I just know motors, so I'm just lucky 🙂 I have God to help me too.

God bless, and good luck!

If you wanted to mod it, now might be a golden opportunity- buy a regular main motor, instead of a tail motor, put the larger rotor on it, a little bit of counterweight, and you have a suped-up s107.
