only one prop runs after crash

[auag]

i'm thinking of buying a used phantom 2..it was crashed and now when you start it only one prop spins and the others just twitch...is this a simple fix or might it be an expensive fix...thanks in advance

The motors maybe damaged by using the wrong screws when removing the prop guards (if they were ever used) or damaged ESCs from a tip-over or other collision.

Calculate what four new motors and four new ESC's would cost you along with what they want for the sick quad. You may find it will total what a new one would cost you. Also if you can do the exchange work. If not figure in another high cost for the labor.

thanks for the replies....what are the esc's?

The are the interface between the battery, radio receiver OR flight controller, and the motor.

There's one near the end of each arm and in this case also contains the LEDs for status monitoring.

They are in the arms of your quad and control the speed of the motors.
