sintered rotors

[andys]

Anyone up on these ? My question is, if I put the new sintered rotor in my novak 6.5 brushless motor, will it still have the performance as a regular 6.5 motor, similarly, if i put one into my 4.5, will it still have the same performance characteristics as a 4.5 ?

Is it simply more efficient, but essentially the same performance, or am I missing something, I read on the Novak site they run cooler and the braking effect is better. If it means the speedo / motor will run cooler, but essentially have the same performance than I might get a couple, anyone ?
