Step 15: Install the FC Power Cable

Before the Isolation Assembly is attached to the chassis, the cable that will provide power the the flight controller is attached.

Parts Needed:

  • 1 - Isolation Assembly, prepared in Step 14
  • 1 - 3-Wire Servo Extension Cable, 4" (#800-00040)


  1. Hold the isolation assembly upside down so that the front of the flight controller is facing away from you.
  2. Carefully feed the cable from the left side in between the isolation plate and power distribution board and plug it into the header at the front of the board (farthest from you).

  1. Flip the assembly over and firmly insert the connector into the Vin header on the power distribution board.

  1. Double-check to ensure that the cable is plugged in correctly:

WARNING: If the 3-pin cable connecting the flight controller to the power distribution board is plugged into the 3-pin header incorrectly, it will destroy your flight controller when you connect your battery!
