307 span sounds like the famous motor glider.... Don't pull hard going fast....

The center section of the box-type front spar is fabricated in the typical KR method of upper & lower booms faced with ply shear webs. Wing is fiberglas over foam. The plane is not new and has accumulated quite a few hours. The booms appear to be vertical grain DF, probably the Mountain variety, very nice stuff (about 20 annular rings to the inch). Their dimensions appears to be 1-1/2" thick by a tad over 2" wide. Question: Is 1-1/2" the normal thickness for these booms? This airframe appears to be a stretched KR-1 fuselage with a KR-2 wing (307" total span). I do not hold a set of KR-2 plans, have no idea as to the original spar dimensions. -R.S.Hoover _______________________________________________ see KRnet list details at http://www.krnet.org/instructions.html
