I was hoping that somebody that actually knew what they were talking about would answer this, but I'll give it a shot, and if I'm wrong, I'm sure the truth will eventually come out. I'm pretty sure the -1 and the -2 use exactly the same 5/8" square spruce for fuselage structure, as well as plywood thickness, which is 3/32 for fuselage and quarter inch for firewall. The wings are very similar, if not exactly identical. Looking at the RR website at http://www.fly-kr.com/kr1.htm and http://www.fly-kr.com/kr2.htm, you can see that the KR-2 wing span is almost 4 feet longer and 18 square feet larger, so something's different somewhere. Certainly, if you had a pile of wood to build a KR-1 wing, you wouldn't have anything left over if you decided to build a -2 wing instead. But like I said, I don't even OWN a set of KR-1 plans, although I've heard they're not much to look at. If somebody would send me their set, I'd love to take a look at them, and then promptly return them. Then I'll know how to answer this question the next time around...
