Hey, Pop.

Here are some schematics I've been putting together for the Kitfox. Let me know what you think. I've reworked the printing instructions a bit for you...

Of note: on the panel page, we can use either the key switch on-hand with a off-(on) DPST [the parenthesized position implies momentary contact] toggle switch to temporarily kill both mags as the engine spins up (avoids shaking off the carbs), or we could simplify with a SPST pushbutton for start and two SPST toggles for each mag. This was suggested by Bob Nuckols (Aero-electric Connection), and allows us separate control over starter and both mags (also makes the mag check during run-up easier). Thoughts?

Just above the starter switch on the www.bandc.biz catalog is an oil pressure switch we could use for activating the Hobbs meter only when oil pressure is above 4psi (providing there's a spot for it along with the gauge sender). Is it worth the extra wire from the Hobbs to the pressure switch?

Another suggestion of Bob's is to replace the manual primer with a small fuel pump/booster pump. (p197) This gives a backup fuel delivery system to work around stuck (eg. frozen) carb floats or blocked fuel lines that would keep the engine alive long enough to make it to an airport or open field. He suggests a simple SPST toggle (or on-off-(on) SPDT switch) to turn on the pump, and needle valves in the fuel line(s) preset to throttle the fuel flow to a rate where the engine runs (however roughly) at a 60-70% throttle setting with the supply to the carbs cut off. We'd need a fuel pump that doesn't allow fuel to bypass it when off, or a separate valve/solenoid to cutoff flow to the primer injectors in the manifold. Since we're not putting in carb heat, and we are planning on running in air temps around freezing, I thought it might be a good idea. What do you think? Too much complexity, or a good emergency fuel delivery system?

For the map light off the E-bus, I'm looking at a goose-neck light close enough to the dash that it could light up the instruments if needed, possibly mounted on the panel itself but stored under the glare shield when not in use. However, they now have LED dash lights meant to be mounted under the glare shield with tape. What kind of dash lights do you envision? I do know you aren't fond of post lights, although I don't mind them.

I found those LED strobe/nav lights you mentioned. That would save quite a bit of alternator load... Plus it looks like they have an option for a belly strobe/LED taxi light. As far as I'm concerned, the more we can use LEDs, the better... Oh, and they have LED cabin lights now too. The lighting portion is still under work. The LC-40 lighting controller is probably overkill...

Save each of these images somewhere on your hard disk by right-clicking each underlined link and clicking "Save Target As...", selecting the directory where you wish to save it (I'd suggest the Desktop for now), and clicking Save. Then open the folder where you save them if it was something other than the desktop. You may be able to use Win2k's photo printing wizard from here on. Right-click one of the images, and select Print. The rest of these instructions assume you see the "Welcome to the Photo Printing Wizard" screen here, and click Next. Select the images you'd like to print and click Next. Select your printer and click next. Select "Full page fax print" and click Next, then Finish.

If you didn't see the photo printing wizard, then right-click each one in turn, and look under the "Open With" sub-menu for the photo printing program you normally use. In there, you should be able to size and rotate the drawing as if it were a photograph. Since its black and white, don't waste photo ink... To print this page, click File / Print Preview in IE, and change from "As laid out on screen" to "All frames individually" and just print the first page.

now as jpegs...
