The only one of three things that I always check on a plane, the Prop, the engine mount and the wing spar/ mount... Otherwise let safety hang to the wind... like the guy at the field who decided to fly his plane backwards... guess what!? He started his engine backwards tooo... HAHA quickest crash u ever saw... less than 10 feet off ground and cartwheeled into the ground..
Maybe he was high on something... who knows
