17. Completing the rudder horn and linkage
Fit the socket-head grubscrew 28 in the swivel connector
barrel 27, and snap it into the "Twin" horn 26.
Apply Zacki ELAPOR® / Hotglue to the recess for the horn,
and push the horn into place as shown in the illustration.
Engage the pre-formed end of the rudder pushrod 31 in the
centre hole in the servo output arm, and slip the straight end
of the rod through the hole in the swivel barrel 27. Check
the neutral position before tightening the socket-head grub-
screw 28 using the allen key 29.

18. Installing the motor (powered glider version)
Screw the motor to the motor bulkhead 50 as described in
the instructions supplied in the power set.
Fig. 19
Connect the speed controller and check the direction of
rotation of the motor shaft (without fitting the propeller)
from the transmitter: when you look at the motor from the
front, the output shaft must rotate anti-clockwise. If this is
not the case, swap over any two of the three power wires
to the motor.
Caution: never connect the flight battery to the speed
controller unless your transmitter is already switched on,
and you are certain that the throttle control is at the "OFF"
position.
Secure the speed controller in the fuselage with Velcro
(hook-and-loop) tape at the left side, and fix the power wires
to the fuselage side with hot-melt adhesive.
The „Solius / Heron" brushless power set # 33 3660 inclu-
ding battery constitutes an excellent power system for the
model.
The components in our power set have been thoroughly
tested, and are carefully matched to each other. Of course,
you may wish to use different batteries, controllers, motors
or radio control system components at your own discretion,
but we will not be able to offer support if you do so.
Alternatively the model can be completed as a pure glider.
For this version you simply have to glue the glider nose
cone 10 to the tip of the fuselage. As an option for the glider
version you may wish to install an aero-tow mechanism
# 72 3470. This is actuated using a scrap piece of snake
outer sleeve (3 / 2 mm Ø) and a length of 1 mm Ø steel rod.
19. Installing the spinner and propeller
First attach the folding propeller blades 82 to the propeller
hub 80 using the cheesehead screws 75 (M3 x 20 mm) and
the self-locking nuts 76. Tighten the screws just to the point
where the propeller blades swivel smoothly when folded
back, but exhibit no lost motion.
Now slip the prepared propeller hub onto the taper collet
79 as shown in the illustration, before fitting the whole
assembly onto the motor shaft. Note that there should be
about 1 mm clearance between the propeller hub and the
front face of the fuselage.
Slip the plain washer 72 on the propeller hub, followed by
the shakeproof washer 73, and then fit and tighten the M8
nut 74. Ensure that the clearance between the propeller hub
and the fuselage is still present! The spinner 81 is secured
using the M2.5 x 12 screw 77.

20. Installing the battery retainer system
First attach the retaining strap 25 to the lower recess in the
battery support plate 51, then glue the plate 51 in the front
of the fuselage using hot-melt adhesive.
Fig. 21
21. Installing the main wheel
Install the wheel 12 in the wheel frame 52 together with the
two spacer sleeves 43, and secure it with the M3 x 30 mm
screw 38 and the M3 self-locking nut 39. Check that the nut
engages in the hexagonal recess.

22. Preparing the tailplane
Glue the two 400 x 1.3 mm Ø stiffeners in the tailplane 6
to strengthen it.
Fig. 23
23. Preparing the tailplane
Glue the spreader plate 58 to the top of the tailplane.
Fig. 24
24. Attaching the horn to the elevator
The elevator horn 60 should be glued to the underside of the
elevator. Take care that no adhesive runs into the pushrod
sleeve (cross-hole). Observe the installation position!
Fig. 25
25. Tubular spars
The tubular spar sleeves / and spar tubes 64 + 65 are alrea-
dy installed in the wings, but the ends need to be cleaned
up slightly so that they are an easy sliding fit in the opposite
rib when the model is assembled.
Fig. 26
26. Reinforcing the ailerons and flaps, freeing up the
hinges
Glue the stiffening tubes 67 in the appropriate channels in
the ailerons and flaps (4x).
When you have done this, cut the ailerons / flaps free at
both ends and flex them up and down repeatedly until the
hinge lines move freely. On no account cut off the ailerons
/ flaps along the hinge line!
Fig. 27
Tip: if the hinge line should tear at any time, a drop or two
of cyano will repair the damage.
27. Installing the aileron / flap servos
The first step is to set the servos to neutral from the transmit-
ter. Fit the output arms on the servo shafts, angled forward
by two splines relative to the case sides (prepare the servos
as a mirror-image pair). This arrangement provides mecha-
nical aileron differential, if your transmitter does not feature
suitable electronic facilities (differential mixer). Angling the
output arms in this way ensures by mechanical means that
the up-travel of the ailerons is greater than their down-travel.
Use this setting to achieve even greater deflections for the
butterfly landing position.
The flap servos in neutral position the servo arm to be rota-
ted 2 teeth to the rear - for housing (mirror image).
The possible rash becomes enlarged down!
