How to wire an RC brushless motor to a receiver

RC motor capabilities have increased in recent years. Brushless motors are leaps and bounds above brushed motors and when they are properly taken care of they can last forever. Brushless motors are not wired directly to the receiver. They must be wired to the ESC (electronic speed controller) and then the ESC is wired to the receiver. The ESC and receiver should not be placed close together on RC aircraft.

Skill level:

Things you need

  • Servo-tape
  • Bolts
  • Wire cutters
  • Wire strippers
  • Soldering wire
  • Hand-held soldering iron

  1. 1

    Determine where to mount the ESC.

  2. 2

    Tape the ESC to the RC aircraft using thick servo-tape.

  3. 3

    Secure the engine onto the engine mount using bolts.

  4. 4

    Measure the ESC wires to the engine connector located on the engine.

  5. 5

    Cut the ESC wires at the appropriate lengths with wire cutters.

  6. 6

    Remove 1/4 inch of the ESC wires' casings with wire strippers.

  7. 7

    Tin the wires with solder.

  8. 8

    Insert the wires into each of the motor's connectors. These connectors are the metal square brackets with holes in the centre located on the motor.

  9. 9

    Solder the wires to the metal connectors.

  10. 10

    Cut the remaining wire so that the wires are flush with the connectors.

  11. 11

    Program the ESC according the ESC owner's manual.

  12. 12

    Connect the receiver wire to the ESC's receiver port. These wires and ports are labelled.
