RE: Reconditioning an Ultra Stick
With the sheeting complete, it was time to take a look at the the ailerons/flaps. The needed to be re-hinged. Rather than put CA hinges back in, I opted to use hinge points. I'm using Great Planes hinge points, not Robart, but they function the same, and for that matter they look pretty similar too. I went with the Great Planes version as they are a translucent white plastic instead of the gray of the Robart's. To reinforce the aileron/flaps I glued a piece of 3/8" triangle stock to the back of the leading edge so the hinge pins would have a little more depth in which to sit. The second picture gives you a better view of the reinforcements. The stacks of wood in the first picture of 3/8" square stock cut to provide reinforcement for the hinges in the wing trailing edge, which is very thin. These were glued in place with plenty of glue to ensure a strong bond. Each hole was drilled with a 1/8" bit and then the first 1/4" was drilled out further with 5/32" bit and trimmed to allow the center of the hinge to sit flush with the back of the wing. All the hinges were dry fitted. The aileron/flaps were measured and notches were cut for each hinge point and the drilled. To test the fit of everything, the ailerons and flaps were all dry fitted as well.
