Press the rubber grommets and the brass tubular spacers into the servo mounting
lugs, as shown in the photo. The servos are held in the wings using the retaining
screws supplied with them, after drilling 1.5 mm Ø pilot-holes for the screws.
Connect the appropriate extension leads to the aileron servos, and secure the
connectors with a drop of cyano or a piece of heat-shrink sleeve to prevent them
shaking loose.
The ailerons can now be installed in the apertures in the wing panels, using the
retaining screws supplied. Drill pilot-holes for the screws beforehand, as already
mentioned.
Allow the servo extension leads to fall through the openings in the wingribs until they
exit at the root ribs.
Use a pencil to draw a centreline on the control surface hinges, as shown in the
photo.
The hinges can now be glued into all the control surfaces, pushing them in as far as
the pencil line.
The next step is to attach the horns to the ailerons. A 6 mm Ø hole has to be drilled
at the appropriate point in each aileron, positioned so that the outside diameter of the
base (12 mm) is at a tangent to the edge of the aileron.
Connect the ailerons to the wings by inserting the hinges “dry” (no glue); you can now
mark the position of the horns correctly. Drill the 6 mm Ø holes, then remove the
covering film under the horn base and glue the horns in the holes.
Allow the glue to set hard, then attach the ailerons permanently by gluing the hinges
in the slots in the wings, leaving an even gap about 0.5 mm wide between the wing
and the control surface.
Note that the pushrod should run parallel to the long sides of the servo, and be in line
with the outside linkage hole in the servo output arm. Cut down the servo output arms
as shown in the photo.
Screw the plastic horn lugs onto the M3 machine screws to the point where the clevis
holes are about 19 mm from the control surface.
Snip off the excess screw length using side-cutters, and file back the cut ends flush
with the plastic lugs.
The aileron pushrods can now be assembled as shown in the photo.
