This might be a hard question to answer, but... I have a P3A, and I can feel a very slight side to side movement in the motor shaft. Not enough to see. But if I grab the top part of the motor and rock it side to side, I can definitely feel the play in there. Is this something I need to replace the motor asap, or risk blowing out a prop and crashing, or am I ok to go (for a while) I'm not seeing any vibration Planning on flying out over open ocean water. Logic would say replace it and be safe, but just not sure how much "wiggle" should be expected.
