One important thing to note is that each prop is locked on the motor with three small legs. I had a very minor crash into a wall during an indoor flight test. There wasn't even a scuff on any of the blades, and the MP flew just fine immediately afterwards. Since the MP was new to me at the time, I pulled one of the blades off to see how the locking mechanism works. Dumb luck had me pull the one blade off that had internal, non-visible damage. One of those three legs had snapped off. The broken piece was still inside the motor hub. The blade was holding on with only 2 legs. It didn't seem to affect the performance at all. Me discovering the damage was a purely incidental finding.
Lesson learned: Even if there appears to be zero damage to the props, take them off of the motor to inspect the underside. Flying with only 2 out of three legs may work... for a while...
