Yep!
And if an IC engine hits you, the second whack is much less and the third whack will stop it. With an electric motor, the current just goes up and the power is still there and it just knocks you out of the way. When I have had an electric motor start out of spite on the work bench, I have the "Search for the Holy Grail" response..."RUN AWAY! RUN AWAY!"
Well, maybe you should learn to keep your body parts free of the winch line. I have a scar under a ring. The line hooked under my ring just as some one stepped on the switch. I was lucky.
I learned after the first time...and be careful with rings around big cells when soldering tabs on them. The closest I have come to crash and burn was when an ESC failed in the "on" mode and it let a 5-turn cobalt run the 1.7 ah batteries down to zip. I had charred balsa all around the ESC but balsa, being a non-resinous wood, just charred instead of setting itself alight. I had the motor timed pretty far farward and I ruined the armature and had to get that replaced. When it comes to stupid mistakes, I am one of the more imaginative.
