2. Locate three hinges for the flaps. Use side cutters 4. Fit the hinge and flap to the wing. Position the to trim one end of each hinge to 11/16-inch flap so it aligns with the wing and that the hinge (17mm). The trimmed end will be placed in the flap. line is equal along the entire length of the flap. 3. Insert the trimmed end of the hinges into the flap. Check that the hinge moves perpendicular to the hinge line.
8. Use a small amount of low-tack tape to hold the flap in position until the epoxy fully cures. Use a paper towel and isopropyl alcohol to remove any excess epoxy before it cures. 9. Repeat steps 1 through 8 to install the remaining flap. 11. Place a T-pin in the center of each of the four hinges. This will center the hinges equally in the aileron and wing when they are installed. 12. Insert the hinges in the ailerons. The T-pin will rest on the edge of the aileron bevel. 13.
15. Saturate each hinge with thin CA. Apply CA to both the top and bottom of the hinge. 16. Once the CA has cured, gently pull on the control surface and wing to make sure the hinges are glued securely. If not, apply CA to those hinges that are not glued and recheck. 8 17. Move the control surface through its range of motion several times to break in the hinges. This will reduce the initial load on the servo during your first flights. 18.
2. Prepare the servo by installing the servo grommets and brass eyelets. 3. Use a #1 Phillips screwdriver to thread a servo mounting screw into each of the holes to cut threads in the surrounding wood. Remove the screw before moving to the next step. 4. Apply 2–3 drops of thin CA in each of the holes to harden the surrounding wood. This will harden the threads so the screws do not easily strip the surrounding wood. 5.
9. Connect a 6-inch (152mm) servo extension to the servo lead. Use a string or piece of dental floss to secure the leads so they do not accidentally disconnect inside the wing. 10. A string is located in the wing to pull the servo lead through the wing. Tie the string to the end of the servo lead as shown. 10 11. Remove the flap servo cover and use the string to pull the aileron extension through the area of the hatch for the flap servo. 12.
15. Use a #1 Phillips screwdriver to thread a 2mm x 8mm self-tapping screw into each of the predrilled holes to cut threads in the surrounding wood.
