12. Installing and fastening the motor
Place the bulkhead holder
⓫
on the fuselage for test purposes (scale
facing downward); if everything ts correctly, glue it onto the fuselage
using Zacki ELAPOR
®
.
Fig. 13
13. Connecting the motor
Since the motor operates in "pressure mode", it must be operated in
counterclockwise direction.
14. Preparing the power unit
Screw the motor to the bulkhead
㉝
and connect the controller. The
entire drive train is inserted into the fuselage from the rear through the
bulkhead.
When assembling the motor, the motor cables are hooked into the cable
protection
㊴
. To do so, insert the drive train, twisted approx. 90° to the
left. Turn the motor with the bulkhead to the right and make sure the
motor cables are caught in the cable holder.

Screw the bulkhead to the motor mount using the screws
㉞
and
㊱
.
Connect the controller to the receiver.
The propeller in the FunJet ULTRA works on thrust, therefore it must be
orientated in the driver in such a way that the front side points forward
in the direction of ight. Fasten the propeller properly and check it for
damage and secure tting prior to each start-up. If in doubt, replace the
propeller.
Fig. 15
The propeller must be balanced!
Caution:
Never stand in the direction of ight when the propeller is running.
Warn others of the danger. This is your responsibility!
15. Gluing the vertical tail
Initially apply the decals to the tail units.
Fit the vertical tails
8
and
9
"dry". If the glued sections do not lie
at on the wing, slightly rework if necessary, e.g. by removing burr.
Apply Zacki ELAPOR
®
to the rudder pockets on the wing and insert the
rudders. Align and x immediately before the adhesive has set.

16. Final assembly
For the receiver, glue a strip of hook and loop tape (hook side)
⓴
to the
corresponding position in the fuselage. Glue the opposite side (velour) to
the receiver. Install the antennas in the slots provided on the underside
of the wings.
For the drive battery, glue the battery mount plate
㊲
into the fuselage,
but rst insert the fastening strap
㊳
. Then glue a strip of hook and loop
tape (hook side) to the mount plate Glue one strip of hook and loop tape
(velour) each on the top and bottom of the drive battery.
Fixing the drive battery:
Initially x the battery at the correct position on the underside. Hook one
side of the fastening strap on the top of the battery to the velour, tighten
the strap and then clip it on.
Fig. 17
The nal exact position of the ight battery is specied when determining the
center of gravity.
Check that the battery is fastened securely prior to each start!
For test purposes, connect all the connections.
Do not connect the drive battery until your transmitter is switched
on and you are sure the operating element for the motor control
is set to "OFF".
It is necessary that your controller has a so-called BEC circuit (receiver
power supply from the ight battery). Now switch on the motor briey and
carefully, and check again the direction of rotation of the propellers (hold
the model during the trial run, remove any loose, light objects located
behind the model).
Caution:
There is a considerable risk of injury due to motors and propellers!
17. Rudder deflections and settings
To achieve a balanced control, the size of the rudder deections must be
set correctly.
The elevator upward (joystick pulled back) 10 mm
and downward (joystick pushed forward) 8 mm.
Set the aileron deections +/- 8/11 mm
(negative differentiation).
If your remote control does not permit these distances, you need to adjust
the pushrod connector.
The neutral position for the rst start is approx. 2 mm to "up".
Once you have successfully acquired the basic settings, the
deections may also be 20% larger.
When ying, you will usually have to trim down. After the rst landing,
mark these rudder positions with a waterproof felt-tip pen on the vertical
tails. Prior to each start, trim to "up" approx. 1 mm above this mark.
After climbing, trim down again accordingly. Another tip for perfectionists:
Like all propeller aircraft, the model rotates slightly against the torque of
the motor around the
longitudinal axis. In our case, to the left at full throttle.
If the remote control allows it, add a little speed => crosswise. However, this
setting is not a "must".
18. Down thrust presetting
The down thrust can be adjusted at the motor mount. The screws
㉞
must be loosened slightly for adjustment. Adjust the down thrust with the
screw
㊱
and then tighten the screws
㉞
again.
For the initial ight, align the bulkhead, making sure it is parallel to the
trailing edge of the motor mount.
Caution:
Do not over-tighten the screws, otherwise the bulkhead will bend!
