Of course the price tag is much more than I want to spend, but my recent tests on the NSR "Baby King" has me hooked.

Shown in Avant Slot but just showing the photo as reference to the motor.
Seems NSR is the only company smart enough to create a motor like this for enthusiasts like us. 17K RPM @ 12 volts, this motor really hits the sweet spot for my needs.
The pods in the Racer models do not use traditional screws into the motor, so that stops me from using any other motor.
Expensive? Yes. Is it worth it to me? Yes. Only you can decide.
