Ruddog RP542 Stock 540 Sensored Brushless Motor (21.5T)

The Ruddog RP542 Stock 540 Sensored Brushless Motor features a revised stack design to improve driveability, and a high-precision sensor to increase performance and efficiency. The Ruddog design team has gone to great lengths to reduce operating temperatures, adding large openings in the housing to lower the weight and ensure optimum air flow, while a ribbed stator collector ring is used to improve heat dissipation. Optimized rotors have been selected specific to the application, with stock motors using a 12.5×7.15×25.8mm rotor.
