Hey All I got this P3A yesterday. I flew it indoors, outdoors, did all calibrations everything perfectly the way it should have been.No incidents, whatsoever. BUT, now i pay attention to the motors and they look slightly odd to me. Like 2 of them are inclined. Here, attaching the photos. But the copter flew fine, absolutely no problems. What would you recommend to do? p.s. also it has this oily trail around it. u can notice in the picture also.
