Many years ago, a buddy and I were trying to start his rc plane. Remember the Duraplane? We had an electric starter too. When the engine finally started I was a bit too excited that it actually fired up and didn't quite clear the prop when removing the glow starter. Well the plastic prop was a bit rough at the edges from bad landings (landings?) and really cut my index finger deep. Luckily his mom was a nurse and fixed me up for another go. That's why I'm going with a club instructor with my first plane. BTW does a dab of paint on prop edges help define the no touch zone? Does it mess up the balance too much?
