Now I can be seen from a long way away ! I have had a few close calls with Navy helo's here in the Pensacola,Fl area so this should improve my visibility a bit. They are SUPER bright ! I can only capture one flash at a time with my camera.

My second problem was as Pete had suggested, the Voltage Regulator was toast, no doubt because I did not realize I had a custom Hotbox and wired it incorrectly. So with that behind me and the weather cooperating here in the UP I made the maiden voyage, and discovered my next challenge. The flight was uneventful other than the Low Fuel Warning Light started to flicker on and off, so I made one loop around the patch and landed. Since I have aircraft aluminum fuel lines from the butt ribs to the header tank I thought perhaps the flexible fuel lines between the butt rib and the tank might be getting pinched, so I swung the wings back and checked them, shortening them up a bit and tried it again, once I rotated and was up about 4' the light came on again, so I aborted. I am running two 13 gal wing tanks into a 2 gal header tank behind the seat. Flex line from the tanks to the butt ribs and Aeroquip fittings and fuel line from the butt ribs to the header tanks, no filters in line. The low fuel warning sensor is a Carlo Gavazzi VP03 and it is new. I have done sustained run ups on the ground at 4500 RPM with no flickering of the light. Any thoughts, appreciated.

It has been mentioned in the past several times, that an up hill run will trap a bubble and restrict fuel flow.

Most likely you have one or two issues. 1 Air in the top of the header tank.. not unusual to have trapped air in the top of the header tank that hasn't found a way out yet and it is tripping the light sensor. It takes some time for the air to get out on a new aircraft. 2 It is a light sensor. sunlight can and does get into the area and trips the sensor.. assuming a PE tank. If it is an aluminum tank that would not be the case. Some have tried painting or wrapping the PE tank to keep sunlight out. Again Congrats !! Fly Safe !!

I just fly around the patch looking for a constant on. If the low fuel stays on solid I land. Hasn't happened yet. (Except the couple of times I really DID run out of fuel.)

Here's a nice set of photos with pretty good written descriptions. It's a flight in the SF Bay Area out to Napa. Not much to do with a Kitfox but according to Matt's guidelines, I'm sneaking it in under the guise of camraderie. :) All those crumbling cliffs with homes being swallowed by the ocean are pretty dramatic. Seems to me to be an unusually clear day. -- Paul A. Franz, P.E.
