If I have things correct, the 954 rotor is one that came with the motor. The 955 is the next one with more torque, the 956 would be high torque. By changing the rotor is the motor still roar spec legal?

Since I may be taking the motor apart to change the rotor, will I gain anything if I change the bearings to ceramic ones? Is it worth the effort? Will they stay together in a crash?

thanks,
