Building instructions
Important: before you start building
Please ensure that all the model components are present in the kit by
checking them off in the Parts List on page 10 and 11.
It is important to build the model on a clean and perfectly flat surface to
ensure that the structure is free of warps, and that the components are
not damaged during assembly. Be sure to cover the building board with
EN
clear plastic film to avoid the components sticking to the surface.
Joints between EPP components are best made using UHU
the procedure: apply a thin film of adhesive to both surfaces to be glued,
then allow it to air-dry for about eight minutes before pressing the parts
together. The strength of the joint is determined by the pressure you exert,
rather than the length of time you exert it.
When CFRP rods and strips have to be inserted into EPP parts, press the strip
into the appropriate slot, then run low-viscosity (thin) Zacki-ELAPOR
liquid along it. A little activator spray will harden the adhesive immediately.
All other glued joints can be made using standard Zacki-ELAPOR
Although the carbon rods and strips are supplied cut to length, you
may need to trim them slightly. If the correct length is not stated, we
recommend that you hold the strip in position, and cut it to length using
pliers or side-cutters. The kit includes an ample supply of carbon strip.
1. Preparing the individual components
The control surface hinges need to be rendered more flexible to ensure
that they move freely when the model is flying. This is accomplished by
folding the control surfaces through 180° before construction; leave them
in this position for about an hour. Fig. 1

3. Installing the servos and the elevator horn
Glue the two aileron servos (2 x Hitec HS-40, # 112040) in the openings
in the wing using a few drops of Zacki; they should finish flush with the
top surface of the wing. Fig. 11
The next step is to glue the elevator and rudder servos (2 x Hitec HS-40,
# 112040) in the appropriate openings in the fuselage using a few drops
of Zacki. Glue the elevator horn

5. Installing the aileron linkages
Use a servo tester or your radio control system to set the aileron servos
to centre (neutral), then fit the large double-ended output levers (supplied
in the kit) on the servos before snipping off the unwanted end. Locate the
hole in the output arm where the pushrod will be fitted, and open up the
hole using a 1.5 mm Ø drill; we suggest you use the central hole. The
aileron pushrods are assembled as shown in the illustration: glue an M2 x

aileron horn, and cut the pushrod to the correct length before gluing the
ball-link to the pushrod. You can now fine-tune the pushrod length using

the threaded coupler; both ailerons should be exactly horizontal when the

servos are at neutral. When you are satisfied, screw the pushrods to the
aileron horns. Fig. 14
