Desolder all 12 of the motor wires that connect to the drones mother boards.

DO NOT cut the cables with wire cutters—they are enameled wire and are a pain in the butt to solder back together and have them still work. Do yourself a favor and just desolder them from the board.

For reassembly, note the order of the cables. While the drone is upside down, black is the top wire, grey is middle, and white is bottom.
