A colleague, complained that his drone wasn't stable. It was wobbling as it tried to maintain position. After landing I noticed that a few of the motor screws were backed out. I tightened them up, not thinking that some of these screws may have been from prop guards. He took the drone home and later found that although the props would spin, it wouldn't take off. Now he gets an ESC warning and the props won't spin, even after I pulled out the long screws. I'm assuming it's just the motors and not the ESC boards. Any way to test the motors individually, he changed some of the screws out before I got to it. I feel somewhat responsible and would rather not buy 4 new motors for him. Anybody have the part # for a P3P motor. I've read that there may be 2 different versions.
Thanks in advance
