Use the ESD Safe Tweezers to remove whichever cable is connected to the prop arm being replaced.

With both top and bottom panels removed, the wires can be traced from the panel to the prop arm to determine the correct wire to disconnect.

Try to avoid disturbing the blue thermal paste covering two of the large board components. If the paste is disturbed or splotchy in places it may need to be removed and reapplied. For more information refer to the How to Apply Thermal Paste guide.
