I painted the panel same color as my cabin interior. I had to do
this a couple of times as my supplier first sold me high gloss paint
instead of the one with a dull finish. The flight
instruments sub panel is drilled to accommodate electric gyros to be
lighted with the UMA system.
This is my fuel pump warning module. When the ignition is turned
on, the alarm will sound and light turn on if the three full pumps are
turned off. The alarm stops as soon as at least one pump is
on. That module evolved a bit and the buzzer is replaced by a
smaller but more robust one. I also added a 1A fuse to protect the
smaller gauge wire to the warning light. Finally, I put silicone to
absorb vibration on the bigger parts (buzzer and relay).
I decided to replace my cheap plastic switches with "real"
ones after I saw an ultralight with those colored switches at Oshkosh
2002. I ordered the new switches from AeroElectrics.
Since those switches have anti-rotation washers, I made a doubler plate
with holes to accomodate the anti-rotation device. That plate is
mounted between the switch and the instruments panel.
And it works!!! I bought a GPS 196 from Garmin that I decided to
put on the flight instruments sub-panel. After all, I won't buy
gyros before I'm ready for night flying and by then, gyros may very well
be obsolete technology. So I moved the instruments around a bit to
accommodate that. I made a sub-sub-panel so those knob openings are
filled out and a point of attach is added for the 4th screw of the
