Well, I have been reluctant to post this because of all the grief I will probably get for being stupid. But in the interest of learning here goes. this picture is what happens when your arm gets hit by an 18x6 prop turning about 4000 rpm. the cut is about 4" long and was 2" deep. Severed the muscle. But I was extremely lucky - it missed the nerves and tendons; because of that I will only be down for about 3 weeks of light use and two months of rehab. this picture was taken two weeks after the accident. I know you are dying to know what happen. Well starting a 1/4 scale Cap, Saito 1.80. !st mistake - Didn't notice the throttle was half open. 2nd mistake - starting the plane alone without tiedown. 3rd mistake - tranmitter not in easy reach. When I kicked it over it instantly went to about 4K, jumped forward, wing hit leg turning prop into arm. 5.5 hours in emergency room, surgery, and about $11K repair bill to BC/BS.
