This happened to me about a year and a half ago. I was not minding my throttle as I should have, one hand on my plane and one on my controller... sweater caught my throttle and I ended up with an open knee cap that stopped the prop(.46 AX). Could have been avoided by simply restraining my plane and minding the throttle. Treat that throttle with respect and restrain your plane. Not just for yourself but for those around you - they'll appreciate it.

Safety first.
