Description
Overview
The RUDDOG Racing RP543 brushless motor series takes competition performance to the next level, refining the proven RP542 platform for even more power, efficiency, and control.

Improved cooling with larger openings and an enhanced finned collector ring reduce temperatures and weight. Custom brake discs — 12.3 mm for 3.5T–5.5T and 12.1 mm for 6.0T–8.5T — ensure optimal handling in all configurations, making the RP543 the ideal choice for serious racers seeking maximum speed and consistency.
