Use a sanding block to sand the wing flat over the exposed area, then glue the
aileron servo plate to the wing using UHU wood glue.
When the glue has set hard, place the aileron servo in the opening and drill 1.5 mm
Ø pilot-holes for the retaining screws.
Fix the servo to the plate using the retaining screws supplied with the unit.
Screw a clevis onto the threaded end of each aileron pushrod, and secure each
clevis with a locknut.
Cut down the servo output device as shown, drill out the linkage hole using a 2 mm Ø
bit, and mount the pushrod connectors using self-locking nuts. Set the aileron servo
to neutral from the transmitter, then fix the output lever on the servo.
Locate the aileron torque rods (projecting from the wings), and screw the lugs onto
the threaded ends until about 3 mm of rod shows at the top; this should give a horn
length of about 20 mm. Connect the clevises to the torque rod lugs and snap them
shut. Push rings of silicone fuel tubing along the pushrods and over the clevises to
prevent them working loose. Cut the pushrods to length, slip the plain ends through
the pushrod connectors, and fit the M3 grubscrews. Tighten the M3 grubscrews
lightly, then set the ailerons exactly to neutral (in line with the wing airfoil) before
tightening the grubscrews fully; secure each with a drop of thread-lock fluid. Ensure
that the servo output lever is parallel to the wing trailing edge.
Gluing the tailplane and fin to the fuselage
Use a soldering iron to remove the covering film over the slots for the fin and tailplane
at the tail end of the fuselage.
This is done by locating the slots with your fingertips, pushing the tip of the soldering
iron through and running it along the edge of the slots until all the film has been
melted away.
Slide the tailplane and fin into their slots. Adjust the position of the tailplane until it
projects y exactly the same length on both sides, and is at right-angles to the
fuselage centreline when viewed from above. Now mark the outside shape of the
fuselage on the tail panels using a felt-tip pen.
Remove the panels and melt the covering film along the marked lines by running a
oldering iron lightly along a steel ruler. Keep slightly inside the lines, then peel the
film away from the wood.
Fit the tail panels in the fuselage slots again, align them carefully and glue them in
place; e recommend UHU wood glue for this. Align the parts carefully as described
earlier: the fin must be at right-angles to the tailplane. This can be checked using a
setsquare. Use pins to hold the parts in place while the glue is drying.
Fitting the control surface horns
The horns should be screwed to the control surfaces in such a position that the
linkage hole for the clevis is exactly in line with the hinge pivot axis, i.e. at right-
angles to it. Drill holes for the retaining screws through the control surfaces. Connect
the clevis on one of the long pushrods to the rudder horn (second hole from the
outside), then slip the pushrod into the guide tube. Screw the horn to the rudder, then
