The throttle pushrod can now be fitted, but first the throttle arm has to be removed from
the carburettor. Connect the pre-formed end (Z-bend) of the throttle pushrod to the
outermost hole in the throttle arm. Slip the pushrod into the appropriate guide tube, and
fit this assembly through the hole in the nose bulkhead from the front. Fit the throttle arm
on the shaft of the throttle barrel in such a way that it is parallel to the carburettor
centreline when the throttle barrel is exactly half-open.
Attach the swivel pushrod connector to the output arm of the throttle servo.
Apply a drop of UHU thread-lock fluid to the nuts to prevent them working loose. Ensure
that the pushrod connector rotates smoothly, but
without
significant slop; take care not
to jam it with the thread-lock fluid.
Install the throttle servo in the servo plate in the fuselage, at the same time fitting the
throttle pushrod through the swivel connector. Glue the throttle guide tube to the
fuselage side at a point about 150 mm from the throttle servo.
Screw a silencer support bracket, e.g. Order No. 607, to the nose bulkhead, as shown in
the photo.
The silencer itself is attached to the bracket using binding wire or a metal clamp.
Prepare the cowl by cutting and filing out the openings for the cylinder head, needle
valve etc., and drilling the holes required. The cowl can be fixed to the model using
either of two methods: either using externally fitted screws or concealed fixings, fitted
from the front.
For the first version hardwood blocks have to be glued in the recesses in the nose
bulkhead; the cowl retaining screws are fitted into these blocks.
For the concealed version the nose bulkhead is glued in the cowl, which is then fixed to
the main bulkhead from the front using four cheesehead screws. In either case it is
important to ensure that the motor crankshaft exits the cowl in the centre of the opening,
and that there is about 10 mm clearance between the cowl and the propeller driver.
Assemble the tailwheel unit as shown in the photos, and screw it to the fuselage and the
rudder. Drill pilot-holes for the retaining screws beforehand.
The final stage involving the fuselage is to fit the dummy exhaust pipes and turbo-
charger. Use your fingertip to locate the opening for the dummy turbo-charger in the left-
hand fuselage side, and melt away the covering film over an area slightly smaller than
the opening using a hot soldering iron.
Glue the dummy turbo-charger to the fuselage.
The dummy exhaust pipes are glued to both sides of the fuselage, as shown in the
photo.
The ON / OFF switch should be fitted in the left-hand fuselage side. Cut an opening in
the fuselage side to suit the switch, and install it using the screws provided.
Assembling the wing
Mark the centreline on the wing joiner, and glue it in one wing panel using plenty of
