Like Joe, I also have a small composite header tank and wing tanks. I carry 9 gallons in the header and 6 1/2 in either wing. I run gravity feed from the header at all times, and transfer fuel from the wings to the header periodically in flight. With this type of configuration, I see very little CG shift on any given flight. Some people don't like having fuel in the cockpit. Some of us don't mind having header tanks. That's your call for your own safety. Not having a header tank in the way makes maintenance behind the panel easier. Ultimately, it's your call.
-Jeff Scott Los Alamos, NM ------------------------- Subject: Re: KR> Fuel header tank Hi Deon, I have a KR-2s with a 12 gal. header tank and am currently building another that I retained the same idea but in a slightly smaller form of 7.5 gal. My theory is that gravity never quits so fuel flow would never quit. Having said that the KR2 is much more pitch sensitive. During any cross country flight I probably only adjust trim one time as the fuel is burned off the header tank and it is really not an issue for the 2s stability. The other main issue is safety which is up to any one persons own tolerance. I personally have a fiberglass header tank and the plan is not to break it. That is not good enough for many good men. You have an aluminum tank which may or may not be stronger and less resistant to a rupture. Another down side to wing only is the fuel line and pump layout and operations. Having mentioned all these items I would likely put in wing tanks and ditch the header. I do not know what stag of completion the plane is in but maybe adding to the fuselage length is an option. It would be a far safer airplane by all accounts. Joe Horotn, N357cj ----- Original Message ----- Subject: KR> Fuel header tank Hi Guys The partial KR2 (original design) I have bought is fitted with an aluminum fuel tank in front of the instrument panel. From the information I have available this is not a good idea (shift of CoG, fire danger etc.) Would you advise that I ditch this and create wing tanks? Given all the ho-ha about CoG issues I am not sure I will be able to pass inspection with this tank in place! This is a big step for me so some advice would be appreciated.
