I don't normally have a problem with Ray's bearings staying attached but
at USIC 2015 my F1M bearing came loose 3 times. At USIC 2013 the bearing
came off at the point where everything was going really well. The delay
while I fixed it allowed the air to change and my next (last) flight was
a dud that dropped me out of first place.

This also isn't a knock on Ray's bearings. It just takes some thought
and some care to keep them attached - especially with the ridiculous
torque that F1M's need.
