My friend and I both purchased Phantom 3s directly from DJI within the last 2 weeks; him the Professional, me the Advanced. I thought the only difference was supposed to be the cameras. But his motors are quite different than mine. His prop tightening tool is a spanner type that grips the circumference of the motor body. Mine is the same as the one I had with my Phantom 2 Vision - the one that hooks on to the frame of the motor where the windings are visible. My wrench does not fit his motors so they are clearly different. The model number of my P3A is W322. Did I get an old model?
