A more elegant solution might be to eliminate ram air venting for the wing tanks, since they have to have pumps anyway. In gravity feed systems the pressure boost from Ram vents is important but for a pump fed system, especially if only transfer, they are really not needed and could be replaced with ambient air vents.

You builder/pilots with completed planes need to get out to the Fly-in's and show us why we are locking ourselves in the garage for years. An ancillary benefit is that the exposure will help keep these great little planes alive as a viable alternative to newer designs. The KR series does not get the credit or consideration that it deserves and part of the cause is the limited exposure at these events. Todd Servaes, V. P. Golden West Aviation Assoc.

If it's because of the way your fuel system is plumbed, i.e. pumps, tanks, shutoff valves, I would just consider changing the plumbing. If you have wing tanks only (like me), I understand the need to run two pumps on takeoff and landing but I'm not sure why you need to be drawing from four tanks. I have a 12.5 gal tank in each outer wing panel. My lines run from each tank to a shutoff valve in the cockpit (mounted side-by-side). Just past the shutoff valve is a "T" that brings the two lines into one. Next in line are two fuel pumps in parallel and then on to the carb. With this setup I can use either or both pumps to draw from either or both tanks. I will land and takeoff with both pumps drawing from both tanks and cruise with one pump drawing from both tanks unless I want to draw from one tank only for balance. An aircraft with a header tank only is drawing from just ONE tank for ALL flight modes. I'd consider other options before you open up the wing to re-do the vents. For those Your results may vary. :-) Larry Flesner ------------------------------ Date: Sat, 12 Jul 2003 08:21:23 -0500 From: "Mark Langford" To: "KR builders and pilots" Subject: Re: KR>Timing Message-ID: <002e01c34878$7dade690$2402a8c0@800Athlon> References: <001801c34860$20b1f660$c0cc07c4@user> Content-Type: text/plain; charset="iso-8859-1" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Precedence: list Message: 8 Eric Evezard wrote: > I have a type 4 long block 2l VW engine.What are the figures for the best timing setting using a Bosch distributor.?What static revs should I try for using a 52 dia x 48 ins. prop.? Many thanks for excellent help in the past.< Eric, No matter what kind of distributor you use, you'll want about 28 degrees of total advance at 2500 rpm or above. That means you'll either need an "advancing" timing light (one that has a knob with degrees on it which you'd set at 28 degrees and then line up the TDC mark with the case split) or a degreed pulley or some other way of knowing where 28 degrees is on the crank. As to what RPM you'll get, I don't think you have a choice. You'll get whatever the engine can pull...

The by products are encouragement from each other, profit from each others errors during the building process and not make the same error. More heads to figure out a difficult problem and best of all camaraderie. You may even be able to get lower prices for items needed by group or fleet purchase. I see only positive things and nothing negative. Good luck to all of you. Bob Stone, Harker Heights, Texas, USA rstone4@hot.rr.com ----- Original Message ----- From: "Oswaldo P.

So, there have been something like 1500 of these built, and not ONE of them has ever had the plywood mysteriously sheer off and create a crash, but you don't think it's good enough? The plywood isn't there just to keep the wind out. It's an integral part of the structure. If nothing else, it acts as a gusset. > It's actually not much work to use this fiberglass skinning.

Sanding the foam will take a few hours. I think you're seriously mistaken here. It can't get any easier to finish something than plywood is. You start with a smooth, flat surface, that really only requires a little sealer and fine sanding and it's ready for primer and paint. You must not have had much experience with fiberglass, but the surface will be far from straight, and the pinholes will eat your lunch trying to fill them all. My guess is it'd take at least three times more effort to skin it with fiberglass then with plywood., and the strength is still in serious doubt...
