Quick Start

  1. Solder cable to pads on the motor.
  2. Waterproof solder connection with epoxy or other potting compound.
  3. Connect the cable to an ESC, send a signal, and the motor will start spinning. That’s it!


It is strongly recommended to insulate the motor. Over time, without insulation, the wires will begin to show signs of corrosion.

Do not operate the motor for extended periods out of water, the bearings are lubricated by the water. Vibrations and noise will be greater when dry.
