I fly electric planes as well as IC and I I never thought much about the prop giving me a hard time because after all, it's a small motor and makes little noise so how bad can it be...right??
Well the thing that I learned on electrics is that it does not stop when the blade hits something...it just slows down and goes on until the juice is gone or it is shut off. I never got bit very bad but a friend got hurt real bad on an Astro 40/geared and I was shocked to see the damage ...it never stopped like a gas engine does...it just keeps chopping you up.
