About a year ago I was testing the engine in my Bud Nolsen 1/4 scale J3 cub and got my thumb in the prop. I knew I messed up when my thumb hit me between the eyes.....lol Hand was not attached to thumb. It severed the thumb twice before I knew it. Me and my wife looked all over the yard for the end piece. I found the middle piece..After about 1 1/2 hours of looking I had to go to the hospital. We called the police to see if someone would come over and help find it. Thay told me that it was not there job to look for body parts so thay sent a ambilance. Sorry for spelling it's hard to type with 1 thumb.
