Introduction

Replace or upgrade your Phantom motors. This guide requires soldering.

Each motor's direction is determined by the order of its leads on the ESC, so when you're replacing, be sure to match the original order. Motors on opposite arms will have the same direction, so check the other arm for reference.

If you're ordering a replacement, be sure to get the right thread direction for your motor, or the propellor collet will loosen during flight.

Pull the two halves of the XT60 power connector apart. It's a tight fit, so be careful not to hit your drone or yank on the cables when it releases!

Lift up on the top portion of the shell and set it on its side. Do not attempt to fully remove the case. The GPS and Magnetometer cables connect the top shell to the rest of the Phantom, be careful not to stress or break these cables. Do not attempt to fully remove the case.

On the Phantom FCP40 (essentially a Phantom 1), the GPS cable connects directly to the Naza controller box, not to the board as shown here. Also the compass (magnetometer) is connected to the main board, not the GPS unit in the top shell, so you don't need to remove it to remove the top shell.

Gently pull the slack of the magnetometer cable through the case bottom shell. The case top shell should now have enough slack to work on the interior of the Phantom. The case top shell should now have enough slack to work on the interior of the Phantom.

  • Be careful not to melt the plastic case bottom shell with your soldering iron or damage any electronic components.

  • When you're reassembling, solder the motor leads back in their original order. This may be different from the picture. Motors on arms across from each other have the same color order, so check the opposite arm for reference.
