Hi This is a great topic to stress SAFETY, I too had 3 bad rc related damages to myself all in 1 week! First I was running a Ugly stick with a OS 91 surpass four stroke full throttle reached over for my transmitter and stopped it dead with my four arm Took about 50 stitches and Lucky I still can use my hand ,the next week I was cutting a 4-40 rod inside my plane and was concerned my safety glasses might fall off and cause a accident, I took them off for the final cut and sure enough got hit with a piece in my Right eye it took 3 eye surgery's " to remove the rust ring "and metal! that same night I just got a new tail pipe and set it on the counter it started to roll went to grab it and cut my thumb wide open! Im very careful and wish everyone to take the time to be safe,It seems most injury's are from not taking the time to think about what your doing and how to do it safely.
