My tail rotor spins, not the main one. Do I need a new 4 in 1? I just got it about a week ago. What should I do? These 4 in 1s are expensive!
Well, it's hard to say what is causing it. Could be the 4 in 1, but could also be the motor, wires, TX, etc.
Do you have another motor you can simply plug into the 4 in 1 to test it? Also, if you hook a battery directly to your motor, does it run? If not, then it is probably bad.
If you have a meter, check the conductivity of the motor leads to make sure they are not broken somewhere....
