    To have unison Aileron control stick movement it’s necessary to have four pulley units mounted to the lower longerons, located on both the left and right sides of the front and rear cockpits. The pulleys were first made from hardwood doweling, then there was a little wire bending, followed with some soldering. After painting the units could be assembled on the plywood bases. The completed pulley units could then be attached to the lower front cockpit longerons with epoxy. The use of some music wire, with balsa spacers, kept the units in position until the epoxy cured. The bottom of the pulley base was reinforced with a plywood gusset before some finishing touch up paint. Well that completes it for the front cockpit, its now on to the rear cockpit with hopefully the same results.

      Working on the LK-10A control sticks, only halfway there but not a total waste of time.

          Thanks Gunny, the shop cat is usually well behaved except if there is an open transmitter case on the workbench. Having only three legs will not stop him from finding a way to lay in it, this time he was sleeping.
          So much for “just for the fun of it” work on the LK cockpit areas for now at least. After cleaning up the workbench today it will be back to work on the wings with finishing the tip sheeting, ailerons and then constructing the spoilers.

            With the wingtip sheeting now complete it was time to cut loose the Ailerons, "free at last". The pre-drilled hinge blocks were installed back when the Aileron spars were placed on the wing ribs so all that need to be done was face the two surfaces. Now working on the Aileron drive system.

              The spoilers have occupied my time these few weeks but "By-Golly" they even work.

                Work continues on the LK but a bit slower to insure it gets done correctly. The fitting of the canopy bows and edge covers takes time also. The front canopy latches are in the process of assembly while the canopy edge covers were painted and primed to make finishing just that much easier. While the paint drys the fuselage wiring harness was trimmed to length and connectors attached.

                  Getting closer to fitting windscreen material. Well maybe after the workbench is cleaned.

                    With a few bare bone photos now taken, it is time to start the covering process. Stay tuned for what comes next.

                      It's just about there, needs a dozen or so steps to finish it to flying condition.

                        A few steps closer to finishing the LK project as the wings and horizontal stabilizer are now done.

                          With the weight and balance complete only as check of the flight controls was needed before the maiden flight next month.

                            Hi Gene,
                            I really enjoyed following your build. The LK looks great and I'm sure will be a great flyer. I was wondering what you used for covering and your painting process. I always want to learn from the master........

                              Jim, Thanks for following the build, covering is Oratex® silver with a cover coat of clear matte and it is much better that the old Soarltex covering. Much lighter and easier to work with. I used Rustolium 2X paint but the trim tape was a failure as it pealed up the base coat of white on the wings, Even patched up, in other words only looks great at a distance. Hope to maiden it at Visalia in May.

                                This past weekend the 1/3 scale Bunny Nose LK-10A took its first flight with only a bit of tremor. A tad nose heavy but elevator trim quickly corrected the situation.

                                After the maiden the aileron rate was reduced by half making the second flight much smoother.
