Real life continue to make this build go slower than I would have liked. I do like to build and remember all of the fiberglass and foam kits that I have built as well as 3 wood and foam XLT's, and 2 Desire's buillt from plans and 2 pieces of fiberglass. That was before kids and all of lifes responsibilities. Thank you for ARF's. Otherwise it would be next year by the time I finished this

The aileron horns are installed similar to the elevator's. Using a bright light it is easy to see the wood block in the aileron. Careful as it is only about 10mm wide. The block in the elevator is much larger. I decided to add a carbon fiber sleeve to the ailerons and rudder to remove the little bit of compression of the surface that I saw in the elevators. (I may redo them as well).
I found a CF tube at my LHS with a 3mm ID perfect for the horns I was using. I believe it is the Midwest brand. The ailerons were marked top and bottom. On my wing the hinge line was 6mm from the wing lip that overhangs the aileron and the horn connection is 7.5mm in front of the screw center. So the holes were placed about 13.5mm back from the wing overhang. A starter hole with the dremel to go through the fiberglass and then a sharpened piece of brass tubing finishes it up. Go in from both sides and hope you meet in the middle. I got lucky with both ailerons as the holes did not need any adjustment. As the wood block in the ailerons is only about 10mm wide I chose the center of it which came close enough to aligning with the servo arm. I glued in a piece of CF tube and sanded it flush. The control rods are the same as the elevators. 1/8" CF tube with Central Hobbies 2mm titanium rod ends glued in with JB Weld. A Dubro 2-56 ball link on the servo end and the new Central Hobbies aluminum horn that adjusts for angled surfaces with ball bearing link on the aileron. The aluminum portion had to be cut down in height. The JR 9411SA servos fit without modification of the mounting area.
