The tailplane
The all-moving tail crank is factory-installed on this model, but you may need to make
minor adjustments to the guide slot for the rear tailplane joiner wire. Plug the tailplane
panels into both sides of the fin using the two 3 mm Ø steel dowels: the one dowel
fits through the front pivot hole in the fin, the second through the rear hole in the
crank, working through the machined slots in the fin. The two tailplane panels can
now be pushed onto the steel dowels on both sides.
CAUTION: it is essential to remove any rough or sharp edges from the ends of the
steel dowels before fitting the tailplane panels for the first time. The tail panels are
retained by an integral clamp which could be ruined by rough edges on the steel
dowels if you force them into place.
CAUTION: if your model is the ARC version, please ensure that the tailplane panels
are the right way up; the top surfaces are marked with a dot at the root rib.
The rudder
Use your fingertips to locate the hinge points on the leading edge of the rudder.
Remove the covering film over the slots, and mark their position on the fin sealing
strip (trailing edge). Drill 3 mm Ø holes at the marked points on the sealing strip,
taking care to drill them in the centre of the strip. Attach the ring-screws to the rudder
by sliding the pivot rod (2 mm Ø GRP) through the hole from either end. Now offer up
the two ring-screws to the holes in the fin sealing strip, and carry out any minor
adjustments required; this is also a good time to check the rudder travel to each side
of centre. The two ring-screws can now be glued in the holes in the fin sealing strip.
Allow the epoxy to set hard before gluing the horn in the bottom end of the rudder:
bend the end of the rudder pushrod at right-angles, fit the horn on the angled end,
and mark its position on the rudder. Drill a 4 mm Ø hole in the rudder, raked forward
at such an angle that the linkage hole lines up with the hinge pivot axis.
