OK...so I did the stupid maneuver of putting the long prop guard screws back into my Phantom 2 and buggered the motors. Initially 3 of them shuttered, telling me about the damage. I purchased 4 new motors. I tried to power up the old ones to find the 3 that were broken and nothing happened. Like the unit didnt receive the signal to power on the motors. All calibrations are good on the remote and the drone and all signals are receiving. So..a few questions I have the Phantom 2 with HD-3D gimbal 1) Does anyone know if there is a way to test if the ESC are bad? 2) should I replace the motors and test them again? 3) could there be another problem outside of the ESC and motors? I live in the middle of no where and truly hard to send to a tech. Does anyone know of someone I can call to help me through this?
