Panel for the Tailwind: clock, compass, suction guage and standard six with the gyros powered by a 9" venturi; KMD150 GPS and TKM MX11 comm radio, SPA400 intercom. Battery will be an Odyssey PC680 and the wiring is based on Bob Knuckolls' (http://www.aeroelectric.com/) Z11 Generic Light Aircraft Electrical system. Currently the wiring is complete but the panel is a ply mock up. I've built a tray mounted to the back of the panel which has all the earth connections and the three power buses (main bus, battery bus, and endurance bus) all contained within a small space for simple marshalling of the cables, fusing, and easy termination. Currently the only engine instrument is the tacho pending a decision on which engine to use
