Measure the distance from the servo output arm hole to the clevis hole in the horn
lug, and cut suitable lengths of 3 mm Ø CRP rod to form the pushrods, taking into
account the length of the connecting parts. Glue the carbon rods into the threaded
couplers.
The servo well covers can now be glued to the wings.
The next stage is to glue the tailplane to the fuselage. Place the tailplane on the
fuselage, and position it exactly central and at right-angles to the fuselage centreline.
Hold the panel in this position, and mark the outline of the fuselage on the underside
of the tailplane on both sides.
Remove the tailplane, and run the tip of a hot soldering iron along just inside the
marked lines, then peel the unwanted film away from the centre of the tailplane.
The tailplane can now be glued to the fuselage. Align the panel carefully as already
described, and pin it in place until the glue has set hard.
The fin can be installed as soon as the adhesive has cured. Place it on the tail end of
the fuselage and engage the front lug in the slot in the former. Check that the whole
base of the fin rests squarely on the tailplane. When you are satisfied, mark the
outline of the fin base on the tailplane as described earlier.
Run the tip of a hot soldering iron along just inside the marked lines in the familiar
way, and peel the unwanted film away from the centre of the tailplane.
The fin can now be glued to the fuselage and tailplane. Tape or pin it in place until
the glue has set hard.
While the adhesive is curing, the two elevator panels and the rudder can be prepared
prior to attaching them. Drill a 6 mm Ø hole at the appropriate point in each control
surface, positioned so that the outside diameter (12 mm) is at a tangent to the edge
of the panel.
To establish the exact position of the control surface horns, attach the rudder and
elevators to the fin and tailplane “dry” (no glue). Remove a circle of film around the
horn holes the same size as the horn base, and glue the horn sockets in the holes.
Check that the full area of the horns rests squarely on the wooden surface.
Allow the glue to set hard, then attach the two elevators and the rudder permanently
by gluing the hinges in the fixed panels.
Push the control surfaces onto the fixed panels, leaving an even gap about 0.5 mm
wide between them.
