I'll put my two cents on this; Perhaps if we were talking 15 or 20 degrees of forward sweep you guys would be correct, but I would like to point out that there have been several sailplanes with forward sweep, the "Genesis" is one and Jim Marske has designed several too. they have less than 5 degrees of forward sweep and are TAILLESS... (the "Genesis" has a very small tail for pitch control)
For a KR "type" of airplane with say 3 degrees of "Leading Edge" forward sweep wouldn't be hard and it wouldn't be UNSTABLE as it is all about balancing forces. It's not like it's an X-29 or a Cornelius Mallard. And might I add that the Bugatti model 100 had a small amount of forward sweep...check it out at OSH this year, it's in there museum. I do AGREE with Mark L though, it's not a KR anymore... Fred Johnson Reno, NV Hal wrote: On a more basic note, I will add two things about forward sweep. 1. Your wings must be much stronger to handle the forces caused by the negative stability. 2. It generally requires a computer controlled flight system to handle the bending moments. Not recommended.
