Default RE: Not another 4* 40...

Tonight I had a little bit of time to start on the left wing half. The first thing to do is cut out all 9 ribs from 3/32" stock using the stock W-1 as a template. Then I placed them on some scrap spar material, pinned them together along with 2 W-1 ribs and sanded them so that they all match. On 3 of them I used a forstner bit to drill holes for the servo lead tube. From there it's just a matter of laying out the modified rib placement on the plans and building up the wing. I've included a couple shots that show the shear webs glued directly on the back side of the spars, rather than in the center as shown on the plans. Another shot shows the 1/4" balsa doubler I added to each root rib. This should make drilling the dowel jole a lot easier.
