Wiring the Gimbals and Pots

The pots are connected to the 5 volt line, so it is crucial to assure that no ground wire can ever make contact with a pot. Referring to the diagram below, +5 volts (pin #1) will be connected to contact C on each pot except the throttle, where it is instead connected to contact A. Then each axis wire is connected to contact B of the appropriate pot. Pin 3 on the plug goes to contact B on the ailerons pot, etc. Once completed, there will be wires left for other functions. A momentary contact switch can be connected to these to add functionality to the controller. Otherwise, any wires that are not used must be removed or isolated.

If the major diameter of the pots is greater than 5/8'', the case must be trimmed to allow clearance around the pots in order for the rear case half to fit properly. There are two (2) recesses in the rear of the battery compartment. These recesses must be cut out to a depth of about 1/4'';. Additional trimming may be required depending on the pot that is used. All wires should be double checked to ensure that no wires are touching and that everything is connected properly. After these steps are complete, the case can be closed.
