How to Remove the Controller on Ghostcat F3, F3X, F4X Pro

What this video covers

Removing the controller (same process on the F3, F3X, and F4X) — for example to resolve a controller "03" error.

Tools needed

A ratchet with a 10 mm deep socket, and scissors/snips.

Steps

1. Remove the six 10 mm bolts under the seat and take the seat off.
2. Cut the zip ties on the controller and at the frame mounting points.
3. Disconnect the four connections under the seat — start with the large yellow XT90; grip the ribbed sections and pull straight apart.
4. Pull the cables down to expose the spiral wrap and unspiral it down to the motor cable.
5. Loosen the knurled motor connection and pull it straight out — the controller is now free to pull out through the controller box.
