Novak/Orion/Reedy motors with a MM?

[tc3_racer_001]

ive got a 3 star in my tc, and it works great once its going. takeoff theres a bit of cogging (fine for bashing but prolly not much good for racing)
i seem to have no brakes, almost liek the mags are stuffed, but it runs cool as. any ideas? ither than the dodgy brakes its awesome (got it second hand for $30 delievered, and 6 months later its working fine, so i cant really complain!)
