Fold the propeller blades
back, and pass them through the ends of
the O-ring
which project from the sides of the spinner. Take care to
avoid the sharp edges of the propeller blades causing damage to the
O-ring
. Fix the spinner to the propeller boss
using the two pan-
head self-tapping screws
.

32. Completing the canopy
Glue the latch tongues
㉘
in the recesses in the canopy
5
. Use thick
cyano initially, and t the canopy on the model immediately, so that the
latch components align themselves automatically. Wait for at least two
minutes before removing the canopy, then apply drops of thin cyano
to the gaps in the latches to glue them in place, ush with the foam.

33. Installing the wings
Slide the wing joiner
㊿
into one of the wing panels as shown in the
illustration, then t the joiner through the fuselage. Before the wing makes
contact with the fuselage, connect the aileron servo lead to the extension
lead already installed in the fuselage. Connect the plug and socket, then
push the wing fully into place; the cable will now form itself into a loop
in the space designed for it. Fit the other wing panel onto the joiner, and
connect the aileron servo lead to the extension lead already installed in
the fuselage, as described previously.

34. Installing the flight battery and receiver
Install the ight pack and receiver in the following arrangement: the ight
battery should be at the extreme nose, the receiver directly behind it.
Deploy the receiver aerial(s) as described in the RC system instructions.
If you are using a 2.4 GHz system, cut slits in the foam material (e.g. in the
area of the canopy ange) and press the short aerials into them.
When positioning these components you should bear in mind the
recommended Centre of Gravity (CG) at point 37. Stick the strips of
Velcro tape
⓴
and
㉑
(loop side) to the inside of the fuselage oor.
Note that the adhesive on the tape is not adequate for this application,
so x the tape with cyano for additional security. The nal position of the
ight battery is determined when you check the model’s balance point
(Centre of Gravity - CG).
Check that the Velcro tape for the ight battery is rmly secured. If you
neglect this, you could lose your battery in ight.
Check that the flight pack is secure before every flight!
Temporarily complete all the electrical connections as described in the RC
system instructions.
Do not connect the battery to the speed controller until you have
switched the transmitter on, and are certain that the throttle
control is at the “OFF” position.
Connect the servo leads to the receiver. Switch the transmitter on, then
connect the ight battery in the model to the speed controller, and the
controller to the receiver. This model requires a BEC-type speed controller
(receiver power supply from the ight battery). Now switch the motor
on briey, and check once more that the propeller rotates in the correct
direction. If it spins in the reverse direction, swap over any two of the three
motor wires to correct it. Always hold the model securely when testing
the power system, and remove any loose, lightweight objects before and
behind the model before the propeller does it for you.
Caution: even small motors and propellers are capable of inflicting
injury!
35. Setting the control surface travels
It is important to set the correct control surface travels, otherwise your
model will not respond to your control commands smoothly and evenly.
Up-elevator (stick back, towards you) should be about 5 mm;
down-elevator (stick forward, away from you) approx. 4 mm.
Rudder 10 mm to either side of centre, in each case measured at
the widest part of the control surface. The ailerons should deflect 8
mm up, and 4 mm down. When you move the aileron stick to the right,
the aileron on the righthand wing should deect up; that on the left-
hand wing down. Please note: when we refer to a model aircraft, the
terms “right” and “left” always apply to the machine when viewed from
above, with the nose pointing away from the observer. If your radio control
system does not include the mixers required to set up differential aileron
travel (as described above), the model will still y well with symmetrical
(non-differential) travels. If you are a beginner, you will probably notice
no difference in any case. However, accurate rolling manoeuvres are
more difcult to y with symmetrical aileron travels. If you cannot set the
recommended travels using your transmitter’s adjustment facilities, you
will have to re-position the pushrod connections, using different holes at
the servo or horn.
36. Finishing the model
The kit also includes a multi-colored decal sheet 2 (A+B). The
individual imprints are plotted and are applied according to our template
(construction kit picture). For a completely individual design, we offer EC
colors # 602800 - # 602809.
37. Balancing the model
Like every aircraft, your EasyStar 3 must be balanced correctly if it is
to y well and stably. To check the Centre of Gravity (CG) you must rst
assemble your model completely, ready to y, and install the ight battery.
The correct CG is marked at a point about 5 mm from the rear
edge of the wing joiner cover, and the model must balance at this
point. This setting corresponds to about 78 mm aft of the wing
root leading edge, measured either side of the fuselage.
Support the model under both wings on two ngertips at the marked
point, and it should balance level. Minor corrections can be made by
adjusting the position of the ight battery. Once you have established the
correct position for the battery, mark this in the fuselage to ensure that it
is always positioned correctly.
