Just completed a successful swap of the new version housing onto an old version motor. The motor is new and there was no race damage on the used, new version housing. Yes, it was difficult to get the courage to remove a brand new housing off of a brand new motor, but I have performed this procedure on P2V+'s and P3's for many years with success.
JWH mentioned a slightly left skew to the gimbal, which I also had. Here's how I fixed that. With the drone shut down, (OFF), I gently moved the whole gimbal, (grabbing hold of the yaw arm), all the way to the opposite side of the skew to force the upper shock plate, (inside the upper portion of the camera mount), to move slightly. There are small rubber isolators that can slide slightly on their mount, creating the skew. I did this several times, noticing improvement each time I did it. The gimbal is now in the "full center" position and repeats this on restart. No guarantee that it will stay centered in a soft crash.
