ok so in the Novak sensored world of motors ... if you thermal the rotors tend to be damaged and will thermal easier the next time. The sintered rotors reduce the heat and are much more difficult to thermal... however the rotors will not be damaged until 250 degrees (or so I've heard) so a thermal does not degraded the performance of the motor. So with the type of setup (MM/Feigao) what is thermalling normally... speed control or motor? And does thermalling the motor damage the rotor at all?
