Hi - I fried a motor by using too long of screws on prop guards.  Purchased both a CW (clockwise, and CCW - counter motor to replace it.  How can I tell which to use.

The motor is in the rear right 5 o-clock position.

Thanks for any advise.

Happy droning,
Pete

They'll have opposite threads on if it's the same as the P3.  Just fit the motor with the same thread that's on the diagonally opposing arm of the aircraft.

Or start the motors and observe.  The dead motor will rotate the same direction as the one diagonally opposite to it.

The motors threads are color coded

2 are silver 2 are black.

Tip of the motor will match what you are replacing with,
CW is black and should be same as top of prop
CCW is Silver and as above
