About this part

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.

This motor is a turd. I knew it was cheap so I wasn't expecting much. And it's so bad I was disappointed.
