Re: KR> Fuel header tank
Having hung upside down by the seatbelt with a header tank on fire I definitely prefer to have all the fuel in the wings, but I had a Midget Mustang with all the fuel in the header tank and currently fly a Mustang 2 with just a header tank. I would certainly put all my fuel in the wings if I was building a new one, but not going to build new wings just to eliminate the header.

KR> Fuel Header Tank
> "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.)" On the contrary, if you've got an aluminum tank it means it's removable. You can't imagine what an advantage that is unless you've got a KR with a fixed fiberglass tank (as per plans). Having the latter is a nightmare if you need to bleed your brakes or get behind the panel - and who is it that doesn't need to do both of these things? My aluminum header tank is 17.2 gallons and I've flown it to almost zero fuel many times with no problem. Usually on trips where I'm landing with almost zero fuel, I've got my baggage area (quite large) behind the seat full of all kinds of stuff which further contributes to an aft CG situation. My KR (Ken Cottle's KR-1½) is 15 feet 8½ inches so it's a little longer than a stock KR . . . one of which I owned back in the 80's. The extra length I've got gives me significantly more room for my baggage compartment and also makes it a nicer handling aircraft. Part of the extended fuselage length is ahead of the CG, so it balances out really nicely. Once you get familiar with flying with an aft CG it's like anything else, no big deal.

Re: KR> Fuel header tank
Awsome! Thanks for all the inputs! I will retain the current configuration. One of the things I really liked is the simple fuel qty indicator - see through pipe! I am glad that the CoG shift would not be a problem and the tank should be much safer during crashing. I do not expect to fly for very extended periods so the amount of fuel will not be a problem.

Re: KR> Fuel header tank
N995BG has 24 gal. header tank[Rand Robinson original fiberglass]Still flying after 27 years.Do I think safety is a good thing? You bet I do.Weight and balance is not an issue with proper distribution of airplane parts.My trim indicator runs in the middle with 15 gallons.With full fuel I was able to make the flight from Cross City FL to Pine Bluff,AR in 5hrs.17 mins.The estimated range was 6 hrs. at the time.15 gallons is all I keep in the plane at any one time.Fly safe and keep building.Tommy W.

Re: KR> Fuel header tank
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.
