RC Glossary


New to the RC Hobbies? What does buggy, bulkhead, nitro mean in radio control car hobbies? Check out the glossary for remote control cars below.

Crown (Armature) --

The outer, curved side of an armature, or depth of the curve as compared to the 'cavity'. The overall thickness of the crown affects a motor's magnetic field (i.e. RPM and torque). Some crowns may be 'grooved' (with a channel in the crown parallel to the motor shaft) to adjust the magnetic field of the motor, or may be 'stepped' (thinner on the leading edge and thicker on the trailing edge) to advance timing and increase RPMs.
