    Mounting the Gear leg sockets......
    Looking at the 3-view and pictures, the wheel axle looks to be even with the leading edge of the wing.

    Finally settled on the gravity method to hold the gear leg in place, also since the leg has about 7 degrees of forward sweep, I opted to angle the bottom mounting plate and back-fill with WestSystem epoxy/404 filler. I placed three 0.130 shims on the back of the mounting plate to get the correct angle

          Do you have a way to adjust the gear in case it wants to nose-over too readily?

          Comment


          • #66
            No Adjustments,.....in for a penny ... in for a pound ....as the saying goes. the wheels should be just behind the leading edge of the the wing ....which should be pretty stable

            Finishing up on the right center section.

                And more clamps.......Was a bit paranoid about inducing any twist into the wing while attaching the lower D-box skin so I decided on the "gravity method again.......small wedges on each rib to push the skin up.

                Attaching the Trailing edge stock.....I'm running the flaps to Rib#7 ( 2 more bays ) to give the wing a 60/40 split ( flap/aileron ) and since I'm going to have winglets the ailerons will be more effective at the tip ( at least that's what I'm telling myself )

                  Outer Flaps and Aileron. Staying with the bottom hinge setup on the outter flap . Drilling the hinge holes I thought was going to be a bit challenging , but turned out not to be a big deal.
                  Using the handle end of the 3/16 round file ( sharpened up a little ) does a great job of drilling matched holes.

                  Built the flap and aileron against trailing edge of the wing for a better match, using 0.060 shims in between the surfaces for spacers. And a jig at the wing tip for a matched aileron tip for minimal sanding.

                  Top hinging the aileron for a smoother look

                    Mockup Winglet to check sizing and shape. The TL90 digital pitch gauge makes it easy to get the right angles.

                      Thanks Gunny,

                      Winglet fun....going to make a plug/mold for the winglets from blue foam so Hotwire templates ( Formica ) were made and stuff was cut.

                      Since I was over zealous sanding the cut ridges and sanded off the top trailing edge, fiberglassing it so I won't put too many dents in it.
