Actually, the dihedral isn't measured from the bottom of the spar, generally speaking. It's more of a centerline angle thing, so measuring off the bottom of the spar isn't an accurate representation of the "real" dihedral. The real dihedral isn't even as high as 3.7 degrees...it's a little lower. I used to know exactly what it was, but obviously it's less than simply the inverse tangent of 5/78 because of the taper angle of the outboard spars. It would only take a few minutes to recalculate it using the vertical centerlines of the spars or the chord lines. I need to get out to the airport right now, so somebody with a little time on their hands is welcome to do that. Otherwise I'll do it tonight...
The KR2 has the same dihedral as the KR2S. Mark Langford N56ML "at" hiwaay.net website at http://www.N56ML.com --------------------------------------------------------
