Control Horn Installation - Horizon Hobby HANGAR 9 Timber 110 30-50cc Manuel D'utilisation

CONTROL HORN INSTALLATION

1. There are two different ball links included with the kit. The ball link
with the fl anged ball is used at the servo arm.
2. The ball link with the non-fl anged ball is used at the control horns.
3. Insert the M3 x 15 socket head cap screw into the hole in the aileron
control horn. Remove any paint using a hobby knife and #11 blade
so the screw fi ts into the hole easily. Check all the control horns.
 The hole should be just large enough for the screw to slide
through, yet still fit snugly in the hole and not move excessively.
4. Use medium-grit sandpaper to lightly sand the aileron control horn
where it fi ts into the aileron. Clean the sanded area using a paper
towel and isopropyl alcohol to remove any debris or oils. This
provides the surface texture necessary for the epoxy to bond to.
 Use low-tack tape on the painted area to help prevent removing
paint from the exposed portion of the control horn. Low-tack tape
will also prevent lifting the paint when the tape is removed.
5. Test fi t the control horn in the slot. Use a square to make sure the
control horn is perpendicular to the control surface. Do not force the
control horn in the slot.
EN
 If the control horn fits tightly, or is not square, use a rotary
tool 3/32-inch (2.5mm) drill bit to carefully enlarge and
reshape the hole. Wrap a piece of low-tack tape around the
drill bit to set the depth of the drill bit so it won't accidentally
pass through the opposite side of the control surface.
6. Slide the control horn plate up from the part that glues into the
control surface and not down from the painted control horn end.
7. Check that the control horn plate fi ts fl ush against the control
surface when the control horn is in position. Check both control
horns at the same time.
 Read through steps 6 through 12 before mixing any epoxy.
8. Remove the control horn from the control surfaces. Mix 10ml of
30-minute epoxy. Apply epoxy to the slot in the aileron and fl ap.
Make sure the epoxy gets into the slot for a good bond between the
surfaces and control horn.
9. Apply epoxy to the area of the control horn that fi ts into the slots.
Use enough epoxy so the control horns will be fully bonded to the
control surfaces.
