ever heard about arc motors?

[florianz]

just recently a guy's castle-neu rotor exploded. and my losi would have exploded as well, if I didn't seal the rotor bonding which was getting loose due to sand. even the lehner's loosing segments... they all can fail. but when the arc's not bonded, that might be a problem. I can't forget that statment of the 75mm on 8s. surviving that, I think they're solid, but I think we wil find out
