22. Attach the link to the servo arm using an M3 x 12 button head
screw, M3 washer and M3 Lock nut. Use a 2mm hex wrench
and 5.5mm nut driver.
 The washer must be placed on the outside of the ball link,
opposite the servo arm. Omitting this could allow the ball
to pop out of the plastic ball link causing loss of control.
23. Secure a 12-inch (300mm) servo extension to the elevator
servo lead.
24. Tie the string in the stabilizer to the end of the servo
extension. Use the string to pull the extension through the
stabilizer.
 The elevator servo lead can be routed in either nacelle. Make
sure to note which side the extension exits the stabilizer
when installing the elevator extension in the nacelle.
25. Secure the servo cover in position using four M2 x 10
self-tapping screws. Tighten the screws using a #1 Phillips
screwdriver.
 To further spread the load on the elevator servo mounting
screws, we advise the used of small washers under
the heads of the mounting screws (not included).
26. Run your fi nger along the bottom of the elevator to locate the
area for the control horns near the pushrod. Use a hobby knife
and #11 blade to remove the covering, exposing the slots for
the control horns.
 There are two sets of slots for control horns, so make
sure the ones selected align with the pushrod.

27. Use medium-grit sandpaper to lightly sand the control horn
where it fi ts into the control surface. Clean the sanded area
using a paper towel and isopropyl alcohol to remove any
debris or oils.
 Use tape on the painted area to help prevent removing
the paint from the exposed portion of the control horn.
Remove the tape once the control horn has been sanded.
28. Test fi t the control horns in the slots. Do not force the control
horn into the slot. Use low-tack tape around the control horns
to prevent epoxy from getting on the control surface.
29. Remove the control horns from the control surfaces. Insert
the M3 x 12 button head screw into the hole in the control
horn. Remove any paint using a hobby knife and #11 blade so
the screw fi ts into the hole easily. Place an M3 locknut on the
end of the screw but leave the nut loose.
 The hole should be just large enough for the
screw to slide through, yet still fit snugly in
the hole and not move excessively.
30. Apply epoxy to the area of the control horn that fi ts into
the slot. Use enough epoxy so the control horn will be fully
bonded to the control surfaces.
31. Make sure to apply epoxy to all the surfaces of the control
horn that fi t into the control surface.
