Associated RC 18T 20T Roadtech Motor MOT0420 by GPM  [MOT0420]

Replacement motor for Associated RC 18T

The GPM MOT0420 is an aftermarket motor produced for the Associated RC 18T platform and supplied as a single replacement unit for 1/18 scale use. The specification lists Roadtech bearings, a 0.4m diameter reference, 20 Turns, and an operating voltage window of 4.8v to 8.4v, which defines the compatible ESC and battery envelope.

For practical swaps this motor is intended to fit the standard motor location on an Associated RC 18T chassis where mounts and dimensions match. When fitting, verify motor clearance and pinion alignment with the spur gear, and choose a pinion tooth count plus ESC that operate within the 4.8v to 8.4v range to tune torque versus top speed.

The description is fitment-focused: use the part as a like-for-like replacement or to trial different turn counts and bearing choices on 1/18 scale Associated RC 18T models. Final performance depends on battery voltage, gear ratio and the rest of the drivetrain.

Use this motor as a direct replacement or a tuning option on Associated RC 18T cars, and double-check mounts and gearing to suit the 4.8v to 8.4v electrical range.
