Building Sequence:
2
A. Servo Mount Assembly.
1. Make a servo tray by laminating together parts A28, A31, A32 and their plywood doublers using epoxy glue. Hold the assemblies together using
clamps as the glue sets.
B. Nose Assembly.
1. Make a pair of A2 by laminating together A1 and A2 and their
plywood doublers using epoxy glue. Hold the assemblies together
using clamps as the glue sets.
2. Then assemble the engine mounting box using parts A1-A2, A3,
A4, A5 and A6 as shown. Use clamps and masking tape to hold the
assembly together as the glue sets.

3
C. Fuselage Frame Assembly.
1. Make two assemblies using A25 and A26 and glue together
using epoxy glue. Ensure you make a right and a left-hand side.
2. Make two side panels by glueing together the A25/A26 laminate
to part A7, ensure you make a right and left-hand side. Add the
pinewood strip stiffeners as shown on the plan.
3. When the glue has set add the engine mounting box to the two
side panels as shown.
4. Then add the pinewood strip cross braces to the lower bottom
as shown in the picture, and on the plan.

4
5. When the above assembly is done, add the bottom ply sheeting
A37, hold in place with clamps as the glue sets.
6. Then add bulkheads A8, A12, A13 and strengthening plates
A39, use clamps to hold in place as the glue sets.
7. Glue pine wood strips to the bulkheads as shown, once the
glue has set sand the edges of the strips to match the bulkhead
contour.
8. Once sanded to shape add the plywood top sheeting to the
front and rear of the front cockpit opening. Then glue into place
2 x A10, 2 x A11, 2 x A15, and 2 x A16 as shown on the plan
and in the picture.

5
9. Using pine wood strips, build over the plan 2 x rear fuselage assemblies, remember you are making a left and right-hand side. When done join
these rear fuselage assemblies to the front fuselage assembly. Do this over the plan to ensure perfect alignment and hold with mini clamps
until the glue sets.
10. Glue together parts A17, A18 and A19 to form the rear cockpit. When assembled glue it to the fuselage as shown in the picture.

6
11. Glue the formers to the top rear part of the fuselage, once again do this over the plan to ensure the sides pull in evenly to the rear. When the bulk-
heads are in place and the glue has set, add the pine wood stringers as shown on the plan and in the picture to form the turtledeck structure.
12. Plank the turtle deck with plywood sheet and hold in place with clamps and masking tape as the glue dries.

D. Horizontal Stabilizer and Elevator Assembly.
13. At the tail end to enable the pine wood strip to bend at the required angle you will need to make a small cut. Then join together 2 x A23 and
A24, once assembled trim with a hobby knife to form the tail into the required point, glue together and hold with clamps as the glue sets. Do
this over the plan to ensure the tail pulls together evenly and to the correct profile.
1. Before you start to build the horizontal stabilizer you will need to
soak the balsa strips in water before bending to the shape shown
on the plan. We recommend that you cover this part of the plan
using clear food wrapping film and scotch tape before pinning the
balsa down in the required shape as it dries out, this will keep the
plan clean and dry. Once the balsa strip is dry, assemble the
structures in the sequence shown. Check the fit of each part and
sand as necessary before glueing into place. Keep the assembly
pinned down until fully dry to stop twisting or warping of the struc-
tures. Next add the trailing edge, the mounting blocks and the ribs
as shown.

2. Trim to fit the 1mm pine wood capping strips as shown on the plan, see step 3 before fitting.
3. Make 1mm deep notches in the leading edge to accomodate the 1mm pine wood capping strips.

9
4. Sand the leading edge to the section shown on the plan. 5. Bend the 4mm stainless steel tube to form the trailing edge of the elevators
according to the shape on the plan. Then drill 2 x 4mm holes for each elevator
in the 10x10mm wood leading edge for the stainless steel tube to fit into. Note:
These holes must be drilled at the angles shown on the plan. When satisfied
with the fit and alignment, glue the stainless steel tube into place using CA glue.
6. Reinforce the elevator ribs on both elevators using 1mm pine wood capping strips top and bottom. Glue a mounting block in each elevator
in the position shown on the plan for the control horns. Trim the excess off the capping strips and then sand smooth to the stainless steel
tube.

10
E. Fin and Rudder Assembly.
1. Trim to length and sand the 8x14x300mm according to the shape on
the plan. Use a round file to form a notch on the tip to accomodate
the 4mm stainless steel tube as shown.
2. Glue all the rudder ribs to the spar as shown on the plan. Add the
1mm capping strips to both sides of each rib.
3. Bend the 4mm stainless steel tube to form the rudder trailing edge to
the shape shown on the plan. Glue the tube between the capping strips
as shown in the pictures. When the glue has set trim of any excess on
the capping strips and sand smooth to the stainless steel tube.
4. Glue the control horn mounting block in the position shown on the
plan and hold in place with clamps as the glue dries.

5. Assemble the ribs and cappings and spars to form the fin, see step
6 before commencing.
6. Cut 6 1mm slots (3 each side) at the tips and in the middle of the fin
leading edge at the angles shown. When satisfied with the fit then
glue the leading edge into place.
7. When the fin assembly glue has dried sand the leading edge to the shape shown on the plan. Drill 3 holes in the rudder post and leading edge of
the rudder to accept the supplied pin hinges. Check the fit and that the rudder moves freely and glue the hinges into place. Note: You may wish
to glue the pin hinges in place after the model has been covered and the tail wheel/skid has been installed.

12
F. Upper Wing Center Section (Fuel Tank) Assembly.
1. Assemble the upper wing center section using the parts as shown.
When done sheet the assembly top and bottom with 1mm plywood.
2. Glue on the leading and trailing edges as shown, then sand to the
profiles shown once the glue has dried.

13
G. Upper Wing Assembly.
1. Indentify all the parts required to assemble the upper wings and construct both panels over the plan on a flat surface as shown. Pin the
components down to ensure the panels stay flat as the glue sets. Note that the ribs have tabs so that they sit on the building board at the
correct angle.
2. Bend the 4mm stainless steel tube to the shape shown on the plan to form the 2 wing tips. Secure the stainless steel tube to the spars and
ribs using epoxy glue, for added strength add a piece of fiber cloth soaked in epoxy glue as shown in the picture. Once the basic panels are
finished remove from the plan and remove the small tabs on the wing ribs using a razor saw.

14
3. Use pliers to bend the metal fittings to shape,and drill holes on the wing spar as shown on the plan for the metal flying wire fittings. Use the
supplied screws and nylon insert lock nuts to hold these fittings in place as shown in the sequence of pictures.

15
4. Please repeat the above sets to make the opposite side wing.

16
5. Reinforce the wing root by laminating 2 x D1 together
with epoxy glue.
7. Install an 8mm wooden dowel and the metal fittings as shown using the supplied
self-tapping screws.
8. Sheet the root end of the panels with plywood
as shown.
6. Glue to the main spar and the leading edge the half ribs which go
between each of the main ribs.

17
H. Lower Wing Assembly.
1. Glue to the wing servo mounts the reinforcing plate "C". 2. Glue the servo mount and reinforcing plate to ribs E8.
9. Glue into place the wing strut mounting blocks then attach the metal fittings as shown on the plan. Thread the supplied 0.8mm diameter
torsion wires through the ribs and attach them to the metal fittings inside the wing. Ensure these wires are tightened as much as possible
to get the most out of the torsional strength.

3. Install the wing spars to the ribs. Please note that the lower
wing spars are pre-shaped, the front spars are bevelled towards
the front, the rear spars are bevelled towards the rear.
4. Use pins to hold the parts down to the plan as the glue dries to stop any
warping of the panels.
18
5. Glue to all the ribs except E1 the rib strengthening plates. Also at this point install the
aileron leading edge spar and the strengthening plates.
