The next step is to make up the pull-pull cables for the rudder, as shown in the next
photo.
Slip the braided cable through the aluminium crimp sleeve (2 Ø / 1.6 Ø x 15 mm),
then through the cross-hole in the ring-screw, then back through the crimp sleeve
again. Firmly crimp the sleeve at two points using round-nose pliers, as shown in the
photo. Solder the steel cables together at both ends of the aluminium crimp sleeve
for additional security.
The clevises can now be connected to the rudder horn lugs. Route the free ends of
the steel pull-pull cables into the fuselage and run them as far as the canopy
opening.
Attach the rudder to the fin once more by inserting the GRP pivot rod.
The two steel cables can now be attached to the servo output lever by completing the
cable ends as already described, and as shown in the photo. Note that the cables
should cross over inside the fuselage, otherwise they will rub against the inside of the
moulding.
The instrument binnacle can either be glued permanently to the canopy frame or
screwed to the fuselage; alternatively it can be installed in the fuselage and arranged
to hinge upwards, as on the full-size sailplane.
The canopy and instrument binnacle
The canopy frame is supplied already attached to the fuselage, i.e. it can be hinged
up to one side after disengaging the latch pin, as on the original machine. Glue the
instrument panel in the instrument binnacle, as shown in the photograph.
Allow the adhesive to set hard, then glue the instrument binnacle to the canopy frame
after roughening the joint surfaces thoroughly.
It is also possible to install the instrument binnacle in the fuselage in the “scale
manner”, so that it can be hinged up when required. Details of the installation are left
to the builder. Before gluing the canopy to the frame, the edges of the frame and the
instrument panel should be painted in the appropriate scale colours; we recommend
the excellent effect paints which are available from DIY stores. The best adhesive for
attaching the canopy to the frame is UHU ALLESKLEBER Kraft. When the job is
finished, paint the outside flange of the canopy white to match the fuselage.
The tailplane
Cut down the threaded shank of the brass horn to a length of 8 mm, apply epoxy to
the hole in the elevator and screw the horn into it. Align the cross-hole parallel with
the hinge pivot axis.
