This flight was over a year ago I was reckless and flying beyond Vlos. I learned my lesson after there was ice buildup on the prop which cause it to vibrate, loosen the screw, and fall off.Oh bummer,glad you find it,,looks pretty chilly,,any signs of a lock tight, I've never had mine off yet even after I fly into a post but all are tight and unmarked,,I'm presuming there should be a factory locktight on them,but yeh definitely missing in flight
