Has anyone encountered or considered a small Head Up Display that might be connected to one of the EFIS systems? I've read of people converting the simple automobile HUDs, but am a bit challenged with the programming? It might not give a huge advantage because the instrument panel is right in your face already, but the cool factor is certainly there.
Also, has anyone used the Simple Digital Systems combination Fuel Injection/Electronic Ignition system on a Lycoming Engine?
Just a few things I've been considering (ok, day-dreaming about).
