Hmmmmm. The KR1B Motorglider numbers that Virge cited of 484 empty weight and 27' wing span yield .66, which is higher than .62. I guess if you want to build a KR1B and call it a legal motorglider, you've got to either make it weigh less (doubtful!), or extend the wingtips another 6" on each end, and you'd be at .62. Sounds interesting... Mark Langford, Huntsville, AL N56ML "at" hiwaay.net see KR2S project at http://home.hiwaay.net/~langford
