i got bit by a gws prop with a gws 400 electric motor
it wasnt spinning fast and i didnt get cut but it hurt like i got my finger smashed in door (dont ask me how i know that)
made me a quick believer in the power of a prop, not i have a lot more powerful motors (brushless and .47 glow) and im more careful
if the esc is connected to the battery, the motor at idle and dont get near the prop
i have those above stands at my field and dont start my engine w/o one (also have wet my pants starting my engine at WOT)
