For this step, you will need to de-solder the wires that connect the motors to motherboard. Or, if you are like me and don't have a solder, you can attempt to rip the wires of.

First of, lift the whole motor out of the plastic mount. This may take some force as it is glued in.

After that, simply cut the cable off of the motherboard, or de-solder it. In the first picture you can see what your controller will look like with one motor missing.

Repeat the same on the other side.
