Description
Overview
The RUDDOG Racing RP543 brushless motor series takes race performance to the next level and refines the proven RP542 platform for even more power, efficiency, and control. A redesigned stator improves throttle response and smoothness, while a precision sensor ensures consistent and accurate performance. Enhanced cooling with larger openings and an improved collector ring with fins reduce temperatures and weight. Custom brake discs — 12.3 mm for 3.5T–5.5T and 12.1 mm for 6.0T–8.5T — provide optimal driving characteristics in all configurations, making the RP543 the ideal choice for serious racers seeking maximum speed and consistency.
