LOL, no not from experience but Im an AMA safety officer so I do have a habit of preaching safety.
However, I fly larger planes and I cant afford to get my lanyard stuck in a 28" prop and get my head neatly removed from my neck. The smaller engines will probably die if it happened but I wouldnt want to find out, a small engine can inflict some nasty and possibly mortal wounds. No thats not from experience,,,, yet,,,, but I have seen other people get cut up pretty badly by a .46.
Another safety point while Im on my soap box. Never stand beside or in front of a spinning prop. If the engine backfires or kicks back it can throw a prop and impale you before you even know you have been stuck. Weird things happen, props come off, spinners explode, a wood prop can have an invisible crack and shatter.... There are just to many reasons to crank it and immediately move to a position behind the prop. [

These are pics from a friends new 40% 3W Votec spinner that exploded when he was running out the engine last week.
