Made good progress today. . . got both wings sheeted, retract holes cut, aileron holes cut. Trimmed the sheeting and sanded in the dihedral. After I got the dihedral sanded in, I went ahead and glued the wings together. We'll see if that was a wise move since I haven't added any of the leading, trailing or cap strips yet. . .

I also uploaded a copy of my spreadsheet showing weights of the various parts as I go along. Does anyone have weights for a 15cc Macs pipe, header, and 2.25" spinner?
