Introduzione

Use this guide to replace an Electronic Speed Controller (ESC) in your DJI Phantom Drone 2 Vision+. The ESC receives power from the central board, and a PWM control signal from the flight controller. There is one ESC for each motor, for a total of four. Removing an ESC requires soldering.

Note: the drone used in this guide probably looks different from yours! It's just a custom paint job, otherwise it's completely stock.

Pinch the top and bottom tabs of the battery case, pull the battery straight out to remove it.
  • Pinch the top and bottom tabs of the battery case, pull the battery straight out to remove it.

  • The metal connectors form a stiff mechanical connection with the battery, you will need quite a bit of force to remove the battery. Hold the Phantom Vision+ with one hand and remove the battery with the other.

Determine if the propellor is clockwise or counter-clockwise rotating.
  • Determine if the propellor is clockwise or counter-clockwise rotating.

  • Each arm is labeled with a rotation icon that shows the direction of propellor rotation.

  • If this icon is missing or you can't read it, you can determine the direction of rotation by examining the propellor.

    • A clockwise rotating propellor pushes air down while rotating clockwise, and the opposite is true for a counter-clockwise rotating propellor, and the propellor blade slopes up in the direction of rotation.

  • Desolder all three motor wires.

  • When replacing a motor, be sure to solder the new motor in following the same wire color order as when you removed it.

    • The motor spin direction is dependent on the order of the wires, and may not match this image exactly. If you forgot the order, check the arm directly opposite for reference.
