My new fuse is 44 inches. But I did not bent the longerons, I sent Mark's email to the Aussie that bent them, and I will send on his reply if and when he replies. OK Phil Matheson SAAA Ch. 20 http://www.saaa20.org/ VH-PKR Australia EMAIL: phillipmathe...@bigpond.com KR Web Page: www.phil

I have an option on a Bing carby off a 6 cylinder Jabiru. With proper jetting, do you think this would work well on an O-200 (as the engine is similar in size)? Paul Smith Brisbane, AUSTRALIA pk.sm...@bigpond.net.au http://kr2spacemodulator.blogspot.com/

The one thing that is important to remember is that the published rear cg is about 2 inches unusable. I have the corvair tucked back against the firewall and wing tanks and a header tank. With full load and the fuel gone from the wings and getting low in the header tank my 2S starts to take on

I can load mine to 1200 # without exceeding the max aft, which I have set at 2" aft of center. Go here: http://krbuilder.org/WeightAndBalance/index.html And click on Final Spread sheet, in the space for the first thumbnail. There is also a link to several that were supplied by other builders. J

After ready this thread about moving the firewall to get more room, it leads me to think there is concern about the CG moving too far forward. This confuses me because I have gotten a couple of EXCEL type weight and balance programs off the KR Net and every one I have tried to plug numbers i

KR1 is a different bird... Build the KR2-S according to the "S" plans and you'll be OK. Are you having an electrical system ? There's a chunk of lead you can move about if you have CG problems, but I doubt it would require the battery in the empennage. Bill Weir wrote: > Thanks to everyone wh

Very few, if any. Now after I put the Vair on my KR2, there may be one with lead in the tail, but we don't know that yet. I don't see how you can extrapolate anything that you think you might know about the KR1, to the KR2S? I don't think your conclusion is wrong, I just don't see the correl

Thanks to everyone who answered re widening fuselage.I think we can sort it out from here. And I gather KR1 was a bit tail heavy so if we move the firewall ahead a couple inches on our KR2S we will be within limits; and if we widden a couple inches we will be in familiar company. As I go throu

If you want to widen the fuse, why not just make the firewall proportionally larger, and extend the length proportionally longer? You are going to have more frontal area anyway and will need room on the firewall for a larger engine. I would think that, that would take care of the bending issues.

OK, here's revision two. I usually try to cover all the angles when I reply to something, and I just glossed over the wood bending issue. I said it's "problematic". I should have said "you'll almost certainly break the longerons when you ask them to make a very sharp bend like 6-8" without g
