JOINING THE WINGS
Stage 1
Locate the aluminium wing joining tube and insert it
half into one of the wing panels as shown. Using a
pen, half mark its centre line.
1.Ensuretubeisfullyinsertedinthewing
Apply plenty of 5 minute epoxy to one side of the wing
joining tube and insert it fully into the wing. Use tissue
or a cloth to wipe up any excess glue that squeezes
out.

Once the glue has cured, trial fit the second wing
panel onto the first, making sure that the two panels
meet without an excessive gap. File the end of the tube if necessary to ensure
that the wing panels meet. Now apply plenty of epoxy to the wing root rib and
the joiner tube as shown. Use 30 minute or 1 hour epoxy to give yourself extra
working time. Slide the two wing panels together. Epoxy should ooze from the
joint and the excess can be removed with a cloth or tissue before it cures. Use
adhesive tape to hold the two panels together as the glue cures ensuring that the
panels are correctly aligned.

Identify the plywood aileron servo
mount and position it on the underside
of the wing centralised to the pre-cut
servo aperture. Use a pen to mark the
position of the mount on the covering.
Using a ruler and a sharp knife, carefully
cut through and remove the covering
film as shown. Attach the mount in
place using cyano or epoxy adhesive
ensuring the lead cutout is towards the
front of the wing.

away a small section of the mount for
the servo lead exit. Install the servo in
its mount and pilot drill (1.5mm) four

Identify the aileron link parts - two pushrods, aileron horns, two nylon snap links and two
swing-in keepers. Using a pair of pliers to hold the pushrod, screw on a nylon snap link until
the thread is just visible through the inside of the snap link. Repeat for the second pushrod. Now screw the two aileron
horns onto the torque rods already installed in the wing. Ensure that both are screwed on the same amount - they should
be approximately 30mm from the wing’s surface.

Connect up the aileron servo to the aileron channel in
the receiver, connect the receiver battery and turn on
the transmitter. Centre the aileron trims and make sure both ailerons are level.
Attach the first snap link to the aileron control horn as shown. Carefully mark
the position where the pushrod passes the servo’s control horn. Using a pair of
pliers, bend the pushrod 90° at this marked point. Using a pair of side cutters,
trim off the excess pushrod length, leaving 6mm after the bend.

Now connect the bent pushrod to the servo horn
using a hole approximately 11mm from the centre.
Slip a swing in keeper over the end of the pushrod and snap it closed over the
pushrod. Repeat this for the second pushrod, ensuring the ailerons remain level.
To complete the linkages, slip a short length of Silicon fuel tubing over each snap
link.

FITTING THE TAILPLANE
Using a sharp knife, carefully
remove the film covering
from the tail and fin slots
at the rear of the fuselage.
Make sure that you do not
remove any wood from the
slots as this will affect the
alignment of the tail and fin.

Now remove the tailplane and using a
sharp knife and a ruler CAREFULLY
cut 1mm inside the marked lines.
Remove the covering from the top and
the bottom of the tailplane. Make sure
you only cut through the film and not
the wood, otherwise the tailplane
may be severely weakened.

Now apply sufficient epoxy to the top
and bottom of the tailplane. Use 30
minute or 1 hour epoxy to give yourself
plenty of working time.
Insert the tail in its slot in
the fuselage and re-check
the alignment as in Stage
10. Excess adhesive should
be cleaned off with a rag or
tissue before it cures.
Make sure it is the correct
way up.

Now remove the fin and using a sharp
knife and a ruler CAREFULLY cut just
below the marked lines. Remove the
covering from the left and the right
side of the fin. Make sure you only cut
through the film and not the wood,
otherwise the fin may be severely
weakened. Remove the film from the
top of the fuselage in the same way. 15.1.Removethelmfromthen 15.2.Removethelmfromthetopofthefuselage

Now apply sufficient epoxy to both sides of the fin and
along the underside. Use 30 minute or 1 hour epoxy to
give yourself plenty of working time. Insert the fin in its slot in the fuselage and check
the alignment. Ensure that it is perpendicular to the tailplane. Excess adhesive should
be cleaned off with a rag or tissue before it cures.

Locate the undercarriage
groove in the underside
of the fuselage. Carefully
trim away the film using a
sharp knife. Insert the main
undercarriage wire legs in
their pre-drilled holes in the
fuselage underside. Now
locate the two moulded
saddle clamps and hold in
position while marking the
fuselage for the mounting
holes. Pilot drill (1.5mm) the

Locate the elevator and rudder control
horns. Turn the model upside down.
The elevator horn is fitted to the
underside of the left hand side of the
tail (looking from the underside with
model pointing away from you). Locate
the horn 25mm from the fuselage
centre-line and align its holes with the
hinge line as shown in the diagram. Mark the position of its mounting holes and
pilot drill the elevator. Screw the horn to the elevator noting that the screws self-
tap into the nylon plate on top. Remove any excess length of screw with side
cutters.

19.2.Installthesteeringarm
Locate the nosegear steering arm and
connect it to the pre-formed z-bend in the
noseleg pushrod. Slide the pushrod into its
tube in the firewall and locate the steering
arm in the steering block with its retaining
screw forward. Slide the noseleg through
the first block, through the steering arm and
into the engine mount. With the steering
arm held in line with the axle, tighten the
retaining screw. There is a flat on the nose
leg wire facing the screw

Prepare the elevator pushrod by screwing a nylon clevis onto one end until the thread just
appears through to the inside of the clevis. Use a pair of pliers to hold the pushrod wire while
you do this. Locate the slot at the rear of the fuselage for the elevator pushrod and carefully trim away the covering as
shown. Now insert the pushrod into its pre-fitted guide tube. Temporarily attach the clevis to the elevator but do not snap
it shut yet.
Test fit your elevator and rudder
servos in the pre-fitted radio tray.
Note that the output horns are
orientated towards the front of the
model. Now fit the rubber grommets
and brass ferrules supplied with your
radio, pilot drill the servo tray and
screw the servos in position using
the screws supplied with your radio. 23.1.Testtyourservosinthetray 23.2. Pilotdrillthetraythenscrewservosinposition

With the elevator held level and the elevator servo centralised, mark where the pushrod crosses
the servo’s control horn. Using a pair of pliers, bend the pushrod down through 90° at this point
and cut off any excess pushrod wire leaving a 6mm length after the bend. Now locate the pushrod in a hole in the servo
horn approximately 11mm out from the centre. Slip a nylon swing-in keeper over the pushrod and clip it to the pushrod
to retain.

To complete the linkage, disconnect
the clevis from the elevator horn. Slide
a short piece of fuel tubing over the

clevis closed. Slide the tubing back over the clevis for additional security.

the clevis (centre hole in the horn) and ensure that the rudder
is level with the rudder servo at its neutral position then snap
the clevis closed. Slide the tubing back over the clevis for
additional security.
Prepare your rudder servo’s horn for the steerable noseleg by fitting a pushrod connector as
shown. Do not over-tighten the nut as the connector needs to pivot in the horn. Apply a small
drop of cyano on the nut to secure. With the servo and noseleg centred, slide the connector over the noseleg pushrod and
attach to the rudder servo. Holding the noseleg centred, tighten the grub screw in the connector to retain the pushrod.

Prepare your throttle servo’s horn
by fitting a pushrod connector as

a small drop of cyano on the nut to secure. Install the rubber grommets and
bushes supplied with your servo, then pilot drill the servo tray and screw the

Prepare the fuel tank by attaching a
length of clunk tubing to the unbent
tube on the tank bung. Using the tank
as a guide, trim the clunk tubing so
that when connected to it, the clunk is
free to move without touching the rear
of the tank. Now insert the bung in the
tank with the bent vent pipe to the top.
