We have found we can gear the JK25k FK motors to hell (12:32), despite magnet racing drag, as consequence of the very strong magnets - amazing motors.
I have just acquired the B52 BB25k motor which has ball bearing and less clunky magnets so wonder if anyone out there has tried these motors and settled on a useful gear ratio for 1/32 magnet racing (or any other) as yet?
Kind regards
Dave
