9. Fitting the fuselage turtle deck
Before installing the fuselage turtle deck, glue the cable retainer
39 in the appropriate slot in the turtle deck.
Trim the fuselage turtle deck 4 to fit, together with the canopy 5.
Mark the position of both parts, then glue part 4 to the fuselage
3. Fig. 11
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.
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.

12. Installing and securing the motor
Offer up the motor mount 11 to the fuselage (integral scale at
the bottom); and carry out any trimming required. When you
are satisfied with the fit, glue the mount to the fuselage using
Zacki ELAPOR. 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; 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 33 or the aluminium bulkhead
included in the Power Set. Connect the speed controller.
CAUTION:
The plastic motor bulkhead is only suitable for motors with
an input power of up to 330 W, e.g. for the power set, # 33
2630.
If you intend to fit the ULTRA Tuning power set, # 33 2647, or
a similar high-performance motor, it is a fundamental
requirement that you install the aluminium motor bulkhead,
# 33 2606, as supplied in the Tuning power set mentioned
above.
If you are installing the Tuning (upgrade) power system with
outrunner motor, the motor wires should be connected to the
cable retainer 39 when the system is installed. This is
accomplished by initially turning the power train to the left
through about 90°, then turning the motor and bulkhead to the
right, taking care to engage the motor wires in the cable retainer
at the same time.
Screw the motor bulkhead to the motor mount, and connect
the speed controller to the receiver, using a servo extension
lead if required.
Fig. 14
The FunJet ULTRA’s propeller 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 session that it is undamaged
and securely fixed. If in doubt, fit a new propeller. Fig. 15
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
Caution: if you opt to use the decal sheet supplied in the kit,
you should apply them to the top surface of the wing now -
before attaching the fins - otherwise there is little chance of
fitting them neatly round 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. Apply ZACKi
Elapor to the fin recesses in the wing, and press the fins into
place. Immediately align them accurately and tape them in
position until the glue has set hard.

16. Final assembly
Stick a strip of Velcro tape (hook side) 20 in the appropriate
position in the fuselage to secure the receiver. Stick the mating
Velcro tape (loop side) 21 to the receiver. In our models we
have always installed the 35 MHz receiver in the fuselage nose,
due to the length of the aerial and the possible interference
generated by the speed controller. With 2.4 GHz equipment
these problems no longer apply, and in this case the receiver
can safely be installed aft of the flight battery.
Glue the battery support plate 37 in the fuselage for the flight
pack, but not before installing the retaining strap 38 (back-to-
back Velcro tape). Stick strips of Velcro tape (hook side) to the
support plate, and apply mating strips of Velcro tape (loop
side) to the top and bottom of the flight pack.
Securing the flight battery:
First place the battery in the correct position and press it onto
the Velcro tape. “Connect” one side of the retaining strap to the
Velcro (loop side) on the top surface of the battery; pull the
strap tight, and finally press the tape surfaces together.
Fig. 17
The final position of the flight battery cannot be established
until you check the balance point of the completed model.
Please ensure that the battery is secure before each and
every flight!
Pierce a hole in the fuselage side leading to the wing duct, and
route the receiver aerial (35 MHz) through it and into the duct,
where it can be secured with adhesive tape. If you are using a
2.4 GHz receiver, allow one of the stub aerials to project out of
the fuselage on each side; the two ends should be angled at
90° to each other.
Temporarily connect all the electrical and electronic
components.
Don’t connect the motor until you have switched the
transmitter on, and are sure that the throttle control is at the
“OFF” position.
Please note that your speed controller must be a BEC type, i.e.
