The Ruddog RP542 Modified 540 Sensored Brushless Motor features a revised stack design to improve drivability, 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 modified motors using a 12.1x5x24.5mm rotor.

Ruddog RP542 540 Sensored Brushless Motor (7.0T)
Wow that motor is insane for the price I paid ( it was on special ) The motor is super smooth at the beginning of the throttle and then Rips like a beast (But still controllable) I played with around 7000hz and 8000hz for drive frequency and ended with 7000hz since it packed more torque , On B6.2D I ended up with 21T with the 78T spur gear (the track is small where I run) I will also test 20T the next time I go practice and race. The Ruddog RP542 is really good quality for the price you pay. The motor never got higher than 115 F after a 5 minutes qualifier or race. The Friend I race with who's got a Hobbywing 7.5T kept screaming at me when we where racing down the straight ( He had no chance the Ruddog has so much more RPM it's not even close) . This thing is a keeper in my arsenal of motors for 2wd racing. Hope it will last a long time. Thanks A-main
