Muffinman: I know exactly what you mean. About 30 years ago (rats now I am dating myself) I built a CL plane. A friend an mine were breaking in the engine. Now I know this is going to sound real stuipid, but remember we were young, and immortal. After we got the engine started he held it right in front of his face with his two hands on the LE's of the wings. Not done with stupidity yet. I was standing to his right and thought I saw the plane start to slip out of his hands. I took my left hand and made absolutely sure I did not hit the prop as I also put my hand on the wing with his left hand. Now another stupid thing, I did not pay attention to my right hand and I put it right into the prop. Luckily it was wood and the engine was one of those RED top engines. (MAC 40 or something like that) Running full speed since CL was only one speed at that time. I now have the scars from 19 stitches on the first finger of my right hand. This stupid incident kept me from getting back into R/C flying until a year ago.

Murphy's law is not theory, it is fact!
