drill, side-cutters, flat-nose pliers, paper scissors.
Building instructions
Please read right through these building instructions so that you have a clear idea
how the model goes together before you start. Make sure you have all the parts you
need, together with the appropriate tools and adhesives for each stage. Use a balsa
knife to remove rough edges from components. Open up holes at marked points, and
move the control surfaces to and fro repeatedly to free them up. Always work on a
clean, smooth, flat surface when assembling the model; a sheet of soft foam will help
to avoid damaging the SOLIDPOR® surfaces. Use cyano glue with activator as
adhesive through construction unless stated otherwise in the instructions. The best
way to use this adhesive is to apply cyano to one surface, and spray activator on the
mating surface before joining the parts.
Cyano-acrylates (‘super-glues’) must never be allowed to contact any part of
your body, and especially not your eyes. We recommend the use of protective
goggles for this reason. Store the adhesive out of the reach of children. Do not
use foam-cyano, white glue or epoxy for this model, as they do not produce
strong joints with the high-density SOLIDPOR® foam material.
The power system
The photo shows all the component parts of the power system. Please note that the
motor should not be installed until the fuselage is otherwise complete. Fix the motor
(included in the motor set (1)) to the motor mount (2) using the four countersunk
machine screws (3). Fit the E-PROP (6) on the motor shaft using the parts (4) to (10).
It is important to tighten the retaining nut (8) very firmly using an open-ended 11 mm
A/F spanner.
Fuselage and tail panels
Glue the motor mount (2) in the right-hand fuselage shell (11), taking care to position
it correctly: the cut-out for the motor cables should be central on the underside. Wipe
away any excess adhesive immediately using a paper towel. Assemble the front wing
screw support (13) and glue it in the fuselage shell. If you wish to install an aero-tow
coupling, glue the rear screw support (14) in place together with the tow-release
servo (C 231). Complete the servo with the output arm and pushrod (15), as shown in
the following photo. Caution: on no account use thin cyano to glue the servos in
place, as this can penetrate the servo case and jam them up completely. Important:
check that the tow-release mechanism works smoothly and reliably before installing
the servo.
Use a servo tester to set the tow-release servo to centre, then fit the output arm
(included with the C 231 servo) on the output shaft in the position shown. Cut the
pushrod (15) to the stated length using side-cutters.
The illustration shows the components for the rudder linkage and tailwheel unit. Set
the rudder and elevator servos to centre using the servo tester, and fit the output
arms (included with the C 231 servo) as shown in the picture. Use a pair of flat-nose
