You guys sure don't give me much credit! Yes, I'm bringing my wings up to stock KR2S length, so dire predictions of my demise might be premature...at least due to WAF or spar failure. Besides my spars are beefier than most anyway (for reasons I dare not go into). I said when I built my wings it'd be interesting to try it both ways and quantify the difference, and after 900 hours it's probably time. I seriously underestimated the effort involved to add a few inches to the wingtips though. Maybe someday I'll get around to optimizing the horizontal stab incidence also (I have a feeling I'll regret bringing that up as well...).
All I really need to know about the KR spar capability is that Marty Roberts routinely pulled 6g's at the Gathering with a 1400 pound gross weight in his KR2. The extra fuel I'm adding is in the outer wing, which poses no flying stresses on the WAFs except during really hard landings. With my usual 1000-pound full-fuel flying gross weight and rarely pulling more than 2g's, it won't be spar or WAF failure that gets me. As far as actual dihedral on the KR2 and KR2S, it's 2.98 degrees. Mark Langford N56ML "at" hiwaay.net website at http://www.N56ML.com --------------------------------------------------------
