ge hole at right-angles to the hinge pivot axis. Mark the
position of the retaining screw holes and drill them 2 mm
Ø.
- Fix the horns to the ailerons and connect the pushrods.
- Remove the covering film over the inboard holes in the
underside of the wing, and run the aileron servo extensi-
on leads out through them.
- Snip off excess screw length at all the horns, and file back
the cut ends flush with the spreader plates.

installing the receiver (electric version)
- Connect the receiving system (RC8), ready for use. A Y-
lead is normally required to connect the aileron servos. If
you wish to connect the aileron servos to two separate
receiver channels, use two short servo extension leads.
- Unwind the flexible wire aerial attached to the receiver
RC8.
- Fix the receiver in the fuselage using Velcro tape.
- Make the strain relief RC9 from a spare piece of servo
output arm, and thread the receiver aerial through it.

- Drill a 3 mm Ø hole in the fuselage top decking, run the
aerial through it, and attach the end to the fin using adhe-
sive tape.

Receiver, receiver battery and switch harness (glow versi-
on)
- Cut a piece of foam to shape to accept the receiver and
receiver battery as shown; this is required to absorb the
vibration caused by the glow motor.
Figs. 107 and 108
- Install the switch harness RC10 and the receiver battery
RC11. Connect the complete receiving system, ready to
work. Deploy the receiver aerial using the method descri-
bed for the electric version - see Figs. 104 and 105.
Final work
Fig. 109
- Glue the side glazing panels and the front screen to the
fuselage using contact cement.
Fig. 110
- Fit the propeller driver on the electric motor, followed by
the propeller and spinner.
Glow version - see Fig. 70
- Install the motor and silencer permanently, and connect
the throttle linkage.
- Connect the fuel lines.
- Install the propeller and spinner.
Balancing
- Mark the CG position on both sides of the fuselage; it
should be 73 mm aft of the wing root leading edge, i.e.
exactly under the main spar - see side elevation on the
fuselage plan.
- Attach the wing to the fuselage and assemble the model
completely, ready to fly. Mark the CG position on both
sides of the fuselage.
- Support the model under the wings at the marked points
using your index fingers, held close to the fuselage.
Ideally the model will now balance level, with the nose
angled slightly down.
- If necessary, move the flight battery or the receiver battery
forward or aft slightly to correct any discrepancy.
Lead ballast can be fitted to correct the CG, but only if re-
positioning the battery is not sufficient. Fix any ballast
securely, so that there is no chance of it shifting in flight
and altering the model’s balance.
Fig. 111 - checking the working systems
- Set the transmitter sticks and trims to centre.
- Switch the transmitter on, then switch the receiving
system on.
- All the model’s control surfaces should now be at centre
(neutral). If this is not the case, screw the clevises in or out
on the threaded couplers to correct.
- Stand behind the model, and move the rudder stick to the
right: the rudder should also deflect to the right.
- Pull the elevator stick back towards you, and the trailing
edge of the elevator should rise.
- Move the aileron stick to the right, and the trailing edge of
the right aileron should rise, the left aileron fall.
- If any function works the wrong way round, correct it
using the servo reverse facility on your transmitter.
- If necessary, adjust the servo travels using the servo tra-
vel limit function on your transmitter.
Fig. 112 - checking the electric power system
- Caution:
adjust the motor control system so that the
motor cannot start running when the throttle stick is at the
idle end-point; see the speed controller instructions for
details.
- Check the direction of rotation of the motor: when seen
from the front, the propeller shaft must rotate anti-clock-
wise. If this is not the case (e.g. if you are using compo-
nents other than those recommended), swap over two of
the motor wires to reverse the direction of motor rotation.
Checking the glow motor power system
- Check the throttle function at both end-points as follows:
move the throttle trim to the forward end-point and apply
full throttle. The carburettor barrel should now be com-
pletely open. If the servo runs to the opposite end-point,
correct it using the servo reverse facility on your transmit-
ter.
- At the idle end-point the throttle barrel should be almost
completely closed, leaving a gap about 1 mm wide. Now
move the throttle trim right back (towards you), and the
barrel should close fully: this will stop the motor. Before
you fly the model for the first time, check these settings
with the glow motor running.
