Omar Khayyam would have flown a Piet. I took his advice today:"Take the cash and let the credit go...", and so went out to thehanger and worked on the Piet's wing. Now all of the ribs are gluedin place, the alieron beams are glued in, the compression struts areglued in, and the wing tips are made. Next step is to install metalbrackets and add the anti-drag wires. Oh, and of course, make andattach the leading edge. Think I'll make that one piece too with a splice in the middle.A one piece wing IS long sitting on the saw horses and you have to walk around the end to get to the work area on the other side.

Thanks Greg, I received both parts. I ran the numbers as per the articleand came up with a maximum of 4000 and change pounds, but the calculationwas only for the flanges. I pulled out the textbooks and did a calculationfor the flanges and the 1/2" ply web and get a Maximum load (read breakingpoint) of 7000 plus pounds. This is for a web height of 4 3/4" and aflange width of 1" by 1" high. ----------
