The RUDDOG RP540 sensored competition brushless motor was developed using the latest technology in terms of manufacturing and production of competition grade motors. Weighing in at a lightweight 170g the motor is made using highest grade materials including Japan-made steel stator plates and high-temperature 99.9% pure copper wire. Large venting openings improve cooling and provide constant performance over the full run, even in hot conditions. The silver can color looks good on, and off the track.
