the nuts carefully: just to the point where the connectors
revolve smoothly, but without wobbling. When you are sure,
apply a tiny drop of cyano to the nut (best applied on the
point of a pin). Fit the socket-head grubscrews 28 in the
pushrod connectors 25 using the allen key 29.
Apply cyano to the horns 24 and place them in the recess,
with the row of holes at the leading edge, facing the hinge
pivot line. Fig. 21
15. Installing the aileron servos
Set the aileron servos to neutral (centre) from the trans-
mitter. Mount the output arms on the servos at 90° to the
long servo sides. Prepare a handed pair: one left, one right.
Trial-fit the servos in the recesses in the wing panels 6 and
7. You may need to make minor adjustments here, depen-
ding on the type of servo you are using. Glue the servos
in place by applying a drop of hot-melt glue to the slots in
the wings for the servo mounting lugs, and immediately
press the servo into the recess. Apply another drop of glue
afterwards if necessary. Fig. 22
16. Installing the aileron pushrods
Connect the pre-formed end of the aileron pushrods 30
to the outermost hole in the servo output arms, and slip
the other end through the pushrod connectors 25. Set the
aileron and servo to centre, and tighten the grubscrew 28
to secure the pushrod.

The "TwinStar BL" brushless power set # 33 2619 forms
the ideal power system for this model.
The items included in the power set are perfectly matched
to each other, and the system has been thoroughly tested. If
you prefer to use a different battery, speed controller, motor
or radio control system components, this is left to your own
discretion, but we are unable to provide support in this case.
17. Preparing the motors and motor mounts
Fix the motor bulkheads 60 to the motor brackets 61 using
four screws 63 each. Fix the motors 50 to the motor bulk-
heads 60 using the screws 62.
Attach the propellers 52 to the motor shafts. Fig. 24
18. Installing the motors, deploying the motor and aile-
ron servo cables => see also powerset manual.
Glue the motor assemblies, including the motor brackets 61,
in the wing-mounted motor pods using cyano. The screw
fixings make it possible to remove the motors at any time.
Run the motor power cables from the motors to the wing root
along the spar channel, and tack them in place using cyano.
Note: if the motors vibrate severely (resonate) in use, check
the balance of the propellers.
Deploy the servo leads towards the wing joiner channels,
and extend them at that point using the 300 mm extension
leads supplied. Cut a recess in the spar covers 8 / 9 to
clear this connection. Now deploy the cables in a straight
line along the front edge of the spar channel, standing the
wires upright (on edge), and glue them in place using cyano.
Fig. 26
19. Gluing the spar covers in place
Carefully trim the spar covers 8 and 9 to fit snugly in the
appropriate recesses in the wing panels 6 and 7. If neces-
sary, cut away a little material to clear the connector of the
servo extension lead. Don't glue the spar covers in place
until they fit absolutely flush with the surface of the wing.
Attach the covers using cyano, taking great care to avoid
adhesive running onto the surfaces which will later make
contact with the wing joiner 40. The next step is to trial-fit
the wing joiner 40, but please do not do this until you are
absolutely certain that there is no active glue inside the
joiner sockets. If you are not sure of this, spray a little acti-
vator inside, and wait for about five minutes. If you neglect
to do this, you run the risk of producing a one-piece wing
which can never be dismantled again.
Figs. 26 + 27
20. Completing the canopy
Locate the slots in the canopy 5 for the latch tongues 23,
fill them with cyano, align the latch tongues with the fixed
latches and push them in as far as they will go.

21. General notes on installing the receiving system
When positioning the flight battery it is important to keep
the stated Centre of gravity position in mind; it will nearly
always be possible to correct the CG by re-positioning the
battery. If not, a little ballast may be needed.
Hook-and-loop tape 20 + 21 is supplied in the kit for moun-
ting the RC system components. Note that the adhesive on
the tape is generally not strong enough for this application;
it is always better to glue the tape to the fuselage using
hotglue.
Install the receiver in the centre of the fuselage, under the
wing, using hook-and-loop tape.
Fig. 29
22. Installing the speed controller
Fig. 30
Fix the speed controller to the fuselage side adjacent to the
flight battery, again using hook-and-loop tape.
Fix the flight battery in its compartment in the fuselage using
hook-and-loop tape. The exact position is established later
when you check and correct the model's balance point.

24. Checking the model's working systems
Switch on the transmitter first. Set the throttle control to
OFF. Install the fully charged flight battery in the model,
connect it to the speed controller, and connect the controller
to the receiver. It is essential that the speed controller is
what is known as a BEC type (receiver power supply from
the flight battery).
Hold the model securely, and remove any loose objects from
the area behind the model. Switch on the motors briefly, and
check the direction of rotation of the propellers.
Caution: even small motors and propellers are capable
of causing unpleasant injuries.
