Caution:
Be sure to glue the fuselage turtle deck in place
securely, as this joint makes a major contribution to
the airframe's structural strength.

Press the latch lugs 23 into the latch clips 22 so that they
engage fully. Apply very little cyano to the inside of the
slots in the canopy 5 and immediately fit the canopy on
the model, sliding the latch lugs into the slots. Fig. 12
Wait one minute, then carefully open the canopy and apply
more glue to the latch lugs to reinforce the joints.
12. Installing and securing the motor
Offer up the motor mount 61 to the fuselage (integral scale
at the bottom); and carry out any trimming required. Glue
the mount to the fuselage when you are satisfied with the
fit. Fig. 13
13. Connecting the motor
As the motor works in "pusher" mode, it must be connected
to run in the opposite direction to normal; with a brushed
motor this means connecting the red wire to the negative
motor terminal, and black to positive. If you are using a
brushless motor simply swap over any two of the three
connections.
Caution!
Always reverse the connections between the speed
controller and the motor, not between the battery and
the controller. It can happen in a moment - and the
result is always a wrecked speed controller!
14. Preparing the motor unit
The whole power train is fitted through the motor mount
from the rear, and threaded forward into the fuselage.
Screw the motor to the motor bulkhead 60. Connect the
speed controller and extend the wires for the servo lead
and the power connections if necessary. Fig. 14
The FunJet's propeller 35 has to push rather than pull, so it
must be positioned in the propeller driver with the front face
pointing forward, in the direction of flight. Secure the
propeller carefully, and check before every flight that it is
undamaged and securely fixed. If in doubt, fit a new
propeller. Keep well clear of the spinning propeller, and make
sure any spectators are aware of the danger. You are
responsible for any accident!
15. Installing the fins
Offer up the fins 8 + 9 "dry" (no glue) and trim them slightly
if necessary. If the joint surfaces do not make good contact
with the wing, remove any rough edges and sand them
back slightly until they do. Spray activator on the joint
surfaces of the fins, and allow it to air-dry. Apply cyano to
the recesses in the wing, and press the fins into place.
Immediately align them carefully and tape them in position
until the glue has set hard. Fig. 16
16. Final assembly
Glue strips of Velcro tape (hook side) 20 in the appropriate
10
positions in the fuselage to secure the receiver and the
flight pack. Stick the mating Velcro tape (loop side) 21 to
the components to be installed.
The arrangement of the airborne equipment should be as
follows:
Receiver in the nose, then the flight battery. The speed
controller should be located in the fuselage tail boom
immediately adjacent to the motor. Fig. 17
The final position of the flight battery cannot be established
until you check the balance point of the completed model.
If the Velcro tape does not hold the battery securely, wedge
the pack against the fuselage turtle deck.
Please check that the battery is secure before each
and every flight!
Route the receiver aerial through a pierced hole in the
fuselage side and into the wing duct, where it can be secured
with adhesive tape.
Temporarily connect all the electrical and electronic
components.
Don't connect the motor until you have switched the
transmitter on, and you are sure that the throttle
control is at the "OFF" position.
Connect the servo leads to the receiver. Switch the
transmitter on. Connect the flight battery (in the model) to
the speed controller, and the controller to the receiver.
Please note that your speed controller must be a BEC
type, i.e. it supplies power to the receiver from the flight
battery.
Now switch on the motor briefly, and check the direction of
rotation of the propeller. Hold the model very firmly before
switching the motor on, and remove any loose, lightweight
objects from the area behind the model before the propeller
does it for you.
Caution: even small motors and propellers constitute
a serious injury hazard!
17. Control surface travels and settings
The elevon travels must be set correctly in order to obtain a
balanced control response: the elevators should deflect up
(stick back towards you) by about 12 mm, and down (stick
forward) by about 10 mm. Set the aileron travels to + 10
mm / - 13 mm (negative differential). If you cannot set these
travels by making adjustments at the transmitter, you will
need to re-position the pushrod connectors on the elevon
horns. The neutral position for the first flight should
be approximately 2 mm "up".
With the model set up in this way, you will usually need to
apply slight down-trim for general flying. After the first landing
mark the correct elevon setting on the fins using a waterproof
felt-tip pen. When you fly the model, trim both elevons "up"
by about 1 mm, i.e. 1 mm above the marked points. After
the initial climb to height, move the elevator trim back to
centre for the remainder of the flight.
