Here's another gem. This lower was sent to me in a CP envelope, the fibre-filled one. It was blasted open 3 times, and was dutifully re-taped by CP:
The battery was twisted, and it took me 2 hours to tear the entire thing down, clean it, regrease and reassemble it before I could even mod the motor. Notice all the fibre dust on the lower, well, it was everywhere, in copius amounts.
