2. Test fit the ailerons to the wing. If the hinges are
difficult to install or don’t go in far enough, carefully enlarge
the hinge slots with a hobby knife and a #11 blade.

3. Drill a 3/32" [2.5mm] hole, 1/2" [13mm] deep, in the
center of the hinge slot. If you use a Dremel
®
MultiPro
™
for
this task, it will result in a cleaner hole than if you use a
slower speed drill. Drilling the hole will twist some of the
wood fibers into the slot, making it difficult to insert the
hinge, so you should reinsert the knife blade, working it back
and forth a few times to clean out the slot.
❏ ❏
4. If the hinges don’t remain centered, remove the
aileron and insert a pin in the center of the hinges.

5. Cut a paper towel into approximately 2" [50mm]
squares. Add six drops of thin CA to the center of the hinges
on both sides. Use the paper towel squares to absorb
excess CA from the hinge gap before it cures. Do not use
CA accelerator; allow the CA to cure slowly.

1. Install the rubber grommets and eyelets on your aileron
servos. Attach a servo extension to the aileron servo. Use
heat shrink tubing or electrical tape to secure the servo lead
to the extension so they don’t unplug in flight. Tie the string
to the servo cord on one of the aileron servos.

2. Fit the aileron servo in the wing. Hold the servo to
the wing so the sides don’t contact the wing and drill 1/16"
[1.5mm] holes for the servo mounting screws. Remove the

Before you glue in the hinges, apply a few drops of
household oil to a tissue. Wipe the tissue over the trailing
edge of the wing and the leading edge of the ailerons,
coating them with a fine film of oil. This will prevent excess
CA, you use for gluing in the hinges, from sticking to the
wing and ailerons at the hinge gap.
