Glue two washers to the inside of the fuselage to act as stops for the wheel doors.
The doors are held closed by a pair of torsion springs, which should be bent to the
shape shown in the photo and glued in place.
1 x right
1 x left
approx. 15 mm
approx. 110 mm
Both ends of the torsion springs are fitted in pieces of plastic tube which are glued to
the wheel doors and fuselage as shown. Do not glue the springs in the plastic
sleeves, as you may need to replace them at some time.
The next step is to mount the rudder servo and the retract servo on the retract unit,
as shown in the photos. The retract pushrod is assembled and installed as shown in
the photo; it consists of a length of M2.5 studding (threaded rod), an M2.5 clevis, two
M2.5 nuts and an M2.5 ball-link.
Now place the undercarriage unit in the fuselage and secure it using the plywood
strap and four socket-head cap screws, as shown in the photograph.
Extend the wheel and screw the wheel brake servo to the front former using the
metal servo mount.
Locate the plastic retract unit cover (supplied with the set), trim it to final size and
place it over the undercarriage assembly. Secure it with two strips of tape, right and
left.
The next step is to install the tailwheel, but first the elevator servo must be fitted.
Locate the tailwheel fairing on the underside of the fuselage and cut off the tip as
shown. Lengthen the elevator servo lead using an extension lead, Order No.
3935.180, and pass the lead through the opening in the top of the fin. Run the lead
down the fin and forward into the fuselage as far as the canopy opening; the opening
for the tailwheel is useful at this point. Drill pilot-holes in the servo plate for the servo
retaining screws, and install the servo in the plate. The elevator pushrod consists of a
length of M2.5 studding, two M2.5 nuts and two M2.5 clevises; the length from clevis
pin to clevis pin is about 62 mm.
Drill holes in either side of the plastic tailwheel cover as shown, extend them to form
slots, and trim the cover to fit in the fuselage.
Drill a 3 mm Ø hole for the wheel axle in both sides of the tailwheel fairing at a point
about 11 mm above the edge of the opening. Glue the plastic cover in the fuselage
aligned with the axle holes, so that the two collets will fit in the circular openings. The
wheel can now be installed together with the two collets.
Attach the rudder to the fin using the GRP hinge pivot rod, and check the position of
the marked points for the rudder horn (threaded rod). Drill a 3 mm Ø hole right
through the rudder at the appropriate point. Fit the studding through the rudder and
screw the horn lugs on both ends as shown in the photo.
