Bell 412 collective head “hardware related” bug found

Guys, there’s a slight change needed to the 412 assembling process. Legs of the bottom-left switch of the head must be cut short (see pic below) – otherwise, it shorts pins of the KY-083 board under it. I have updated assembly manual accordingly.

If you have problems with multiple button presses and/or hat switch only working in 2 directions, this is most likely the case, please update.
