You can't return down the vent tubes. There is no place for the traped air to go. --- Larry Flesner wrote: > At 10:53 PM 1/7/2007, you wrote: > >the wing > >tank vents will be plumbed to enter the header tank > at about the full level. > >Only the header tank will be vented

Well, I don't think the computer knows much about the shape of my tank, and the numbers are only calculated numbers. I did weigh it with no fuel and with full fuel to get the calculated moment (station) of the fuel. See N64KR at http://KRBuilder.org - Then click on the pics See you at the 2007

My preference on my Corvair KR2S is to run the header because of my gravity feed carb - Gravity is pretty dependable - I think it is more reliable than a fuel pump (no reported incidents of loss of gravity other than with some assossiated UFO sightings) I have a 13 gallon header and 10 gallons

You can always build a small header, leaving room for baggage and access to the instrument panel, and pump to the header from the wing tanks and have the best of both. See N64KR at http://KRBuilder.org - Then click on the pics See you at the 2007 - KR Gathering There is a time for building and

Guys, I guess that I'm in the mood to throw my pennies into the pot here. I have the exact set up that is being talked about here and have no problem with it for low pressure or CG management. I have in fact been testing max climb angles and durations at those angles. I don't have the

With a 250 lb pilot, the shift is .862". I thought it was the other Mark and he weighs less than me. See N64KR at http://KRBuilder.org - Then click on the pics See you at the 2007 - KR Gathering There is a time for building and a time for FLYING and the time for Flying has begun. Daniel R.

Hi Guys I have been thinking long and hard about the possibility of not installing my aluminum header tank and just sticking with the two outboard wing tanks. I did build the tank with its CG as close to the spar as possible. It will take about 50 litres to fill it. I would like to hear from those

Thanks Mark J and Larry F for the informative replies. I have only one question for Larry, If I read your post correctly, you have a gap of 10" behind the main spar and then your tank extends rearwards from there. If so can you give me the reason for the gap. No specific reason, it just seems

Doug Said The KR2S, when built without the plans located header tank, will not have much CG shift. I forget the exact number, but mine with wing tanks shifts less than two inches from empty fuel light pilot to full fuel with heavy passengers. I think Mark Jones said his was closer to an inch

Hi Phil, The header tank is not required for balance. You can adjust the C of G = by altering the engine mount length. This is quite easy if you are = making your own engine mount or are up to modifying it. When changing = engines I did exactly that and got to within 3mm of my desired result.

You could always use spacers on the firewall to move the engine mount forward 1 or 2 inches and then you wouldn't have to modify the engine mount at all. A little W math should get you into the ballpark for spacer thickness. Denny Barry Kruyssen wrote: Hi Phil, The header

I have wing tanks with an electric boost punt sending to the header tank. I also have an VW engine pump and electric boost. It appears that each of these pumps will allow fuel to flow through them in the case of failure. I am wondering why I can't eliminate the vent from the header tank and

KR>header tanks

IF I understand what you are saying. If you remove the vent from your header tank you will have an air chamber. You will not be able to fill the header tank as air pressure will build and prevent fuel from entering. The only way the air will be able to escape is through the carburetor. You may
