connect the pushrod to the horn lug, and re-connect the clevis to the servo output
arm. Repeat with the second aileron.
The model can be fitted with either a fixed or retractable undercarriage. For the fixed
option the wire undercarriage legs have to be inserted in the hardwood blocks
provided. Screw the aluminium plates to the hardwood blocks as shown in the photo,
then install these assemblies permanently in the wing.
If you wish to install pneumatic main undercarriage retract units, the first step is to
connect the air lines (hoses).
Cut two pieces about 180 mm long from the air hose supplied, and connect them to
the nipples on the retract units.
Cut the plastic wheel wells to shape, trim them to fit the recesses in the wings, and
glue them in place permanently.
Now place the retract units in the wheel wells, drill pilot-holes for the retaining screws,
and fix the retract units in place.
Slide the wheel legs into the retract units, position them with the spring coil facing
directly aft, and tighten the clamping screws firmly. Now fit the wheel axles (with
wheels attached) on the wheel legs and retract the wheels by hand; adjust the
position of the wheels so that they lie in the centre of the plastic wells.
Mark the correct length of the wheel legs, cut off the excess material, and sand or file
a small flat in both wheel legs for the grubscrews, to ensure that the axles remain
correctly in line. Check that both wheels are positioned exactly parallel to the
fuselage centreline.
Position the cruciform output levers on the elevator and throttle servos as shown in
the photos, and press them onto the servo output shafts.
The pushrod connectors must swivel smoothly on the output arms, without noticeable
slop.
Elevator
Throttle
Place the rudder, elevator and throttle servos in the servo plate. Ensure that the
servos are at centre before proceeding.
If you are installing a retractable undercarriage, cut away the fuselage sheeting on
the underside to accept the noseleg unit, and fit the retract mechanism in the
opening. Mark the position of the retaining screws, drill pilot-holes and screw the unit
to the fuselage.
Assemble and install the noseleg as shown in the photo. Here again, a flat must be
ground into the wheel leg to prevent the axle rotating.
The steerable nosewheel linkage consists of two steel cables, and is installed as
shown in the photo. The nuts on the ring-screws are used to adjust the length of the
cables.
