Ive got about 5, 1/4"-1" long scars ontop of my right hand from the prop on my hyperwing hitting it while hand launching. Since then Ive did away with hand launching by the little fairing on the bottom, now I just grab it by the wingtip and sling it out, works 100% better.

Another time while fidling around with the pushrods on my hyperwing I bumped the throttle and cut up 2 of my fingers (pointer and middle), werent very bad cuts but it hurt like hell to write anything as the pen layed right on top of them.

Just 2 days ago when I was adjusting the servos on my ultimate I bumped the throttle stick and the plane took off full throttle right into my arm (the plane was on the ground facing me), now ive got two big cuts on my right arm. They were bleeding so bad I had to take a paper towel folded into a big sqaure and tape it over the cuts to keep the blood from going everywhere.
