Progress has been slow recently due to my relocation to Sweden, but I was able to complete the fuel levers and fix some light plates. Cleaning the throttle levers with an electric brush proved to work nicely. The potentiometers for the fuel levers have been connected to a D-SUB connector for easy removal of the whole unit. The rods connecting the potentiometer with the actual lever come from RC models. The metal plate has been CNC cut and fits perfectly a 3D printed part allows attaching the connector.
