    Scale BUSA Super Cub

    Here are the seams referenced in the Stits manual, see the envelope requires only a single stitch. I think on the next one I might try the seam right above the single stitch, the modified folded fell in two steps

    I must say it works better than I had hoped. Did a little work on the engine. The intake had 1 10.25 mm throat, the new carb has 1/2" bore (13mm). Ordered 1/2' ball end mill to open the throat to 1/2",took longer to set up the piece on center than to do the mill work. Should have taken a...

    I'm only guessing here but I believe the plywood is too large. In the photo below there is a flange that the rear window fits into, I would image the fabric was glued to the flange and glued into the flange as well, than a reinforcing tape was applied on top the fabric over the the flange...

    Have the anti-servo tab cut free. Put 2 layers of carbon on the both the trailing and leading edges. Fitted the tips on. The tab will be top hinged using two DuBro quarter scale hinges two per location. I do not plan to split the tab like the full scale but there will be four hinges in the...

    For the window area I would mask the windows, put a light coat of Poly Tac around the window, attach the fabric, preshrink the fabric, then paint the solid area around the windows with Poly Brush and trim around the windows after the Poly Brush dries.
