Let me add some commments, Unleash.
-NC6 motor is a beast! perhaps 90% of ProRace success is this motor. Hope Ninco sells it as spare part soon.
About Gr. N:
-Some clubs don't accept ball bearings so if you want to race with the ProRace you must replace them for standard bearings.
-To run on spanish rally tracks a guide with suspension is recommended, so some clubs allow to replace standard guide for "active Ninco" if you can do it without modifiaction.
