Wow Rodney! Glad to hear that YOU weren't harmed (at least physically).Question? Was the ESC armed prior to the removal of the servo lead?The reason I ask is that I have always set up my electrics so that the ESC doesn't arm until I take it out of throttle hold that first time. I am on throttle hold when I connect the ESC battery. My throttle hold point is slightly above zero throttle. So until I come out of throttle hold with zero throttle on the collective stick the ESC doesn't arm. I usually don't do that until the Heli is on the line and ready to fly.This is the same setup used for Auto Bailout on the Castle ESC's. No sure if this would have prevented this mishap but this is something you might want to look at if this is not your current setup.
Rich,Glad to hear your friend got away with only the stitches. Flying alone is a practice I try to avoid. At least with anything larger than a 450. CheersAlanAlan, I try to avoid flying alone as well but, sometimes a blue sky and my love of flying get the better of me. Rich
