The two rudders are actuated by a factory-fitted bellcrank; remove the bellcrank by
undoing the retaining screw. Drill out the holes for the pushrods and the swivel
pushrod connector using the appropriate sizes of drill. Fit the swivel connector,
ensuring that it rotates smoothly, but without noticeable slop. Connect the pushrod
from the rudder servo to the bellcrank, then connect the pushrods from the horns to
the bellcrank before re-installing the bellcrank. A drop of glue injected into the hole
for the retaining screw will prevent it working loose. Ensure that the pushrods from
the horns run through the cross-hole in the swivel pushrod connector.
Snip off excess pushrod material using side-cutters.
The two rudder pushrods are joined in the centre using the swivel pushrod connector
(with 2 mm Ø cross-hole).
Apply UHU schraubensicher to the clamping screw to prevent it working loose.
Locate the hardwood tongue at the leading edge of the tailplane, slide it into the slot
in the fuselage, and fit the M4 plastic screw to secure it.
The undercarriage
The forward cockpit glazing must be removed before the noseleg can be installed.
Slip the noseleg through the holes in the bracket from the underside, fitting the
steering lever at the same time.
Note that the steering pushrod has to be connected to the outermost hole in the
steering lever before you install the noseleg. Apply a drop of UHU schraubensicher to
the retaining screw to prevent it working loose. The cockpit glazing can now be fixed
to the fuselage using clear adhesive tape.
The main and nose wheels can now be fitted to the wheel axles; each is retained
using a collet on each side. Apply a drop of UHU schraubensicher to the collet
screws to prevent them working loose. Check that the wheels rotate freely, but
without excessive slop.
Elevator and nosewheel servos
Press the rubber grommets and tubular metal spacers into the servo mounting lugs,
as described for the aileron servos in the wing. Place the servos in the servo plate in
the fuselage, drill 1.5 mm Ø pilot-holes for the retaining screws, and fit the screws to
secure the servos.
Swivel pushrod connectors are again fitted to the servo output arms in order to
connect the pushrods to the servos. Ensure that the swivel connectors rotate freely,
without significant slop; this is particularly important for the elevator servo. Snip off
excess pushrod material using side-cutters.
