- Slip the double ball-links S5005 onto the flybar, and press
them onto the appropriate linkage balls.
Note: when fitting the double ball-links onto the linkage
balls note the position of the raised lug on the links. The
lug must always be on the outside of the joint.
- Screw the inertia weights S5068 into the flybar paddles
S5069 as far as they will go.
- Fix the inertia weights to the flybar by tightening the grub-
screws S0041 into the grooves in the flybar.
Before tightening the grubscrews set the paddles exactly
parallel to each other and to the collective pitch compen-
sator hub S5087.
- Note: the double-links S5091 are designed for 3-D flying
in conjunction with powerful motors and symmetrical-sec-
tion rotor blades.
- The pushrods S5045 and S5046 should then be set to the
stated lengths.
5.3 Mounting the rotor head,
installing the rotor head pushrods
- Fit the rotor head on the rotor shaft and secure it with the
screw S0114 and the self-locking nut S0090.
- Fit the ball-links S5043 on the pushrods S5045 / S5046
and set them to the lengths shown in the drawing.
- Attach the pushrods to the rotor head and the swashplate
inner ring.
- Rotate the clamp S5042 until the pushrods S5045 are
exactly vertical.
- With the servo output arms horizontal, adjust the level of
the swashplate driver so that the top edge of the clamp
S5042 is flush with the top face of the driver yoke S5105.
- In this position tighten the grubscrew S0041 to fix the
clamp to the main rotor shaft.
Stage 6
6.1 Assembling the tail rotor gearbox
- Place the ballraces S4035 and S4350 in the tail rotor gear-
box housing S5064.
- Slip the tail rotor drive coupling S5114 through the ballra-
ces S4035 and S4350.
- Fit the 20-tooth bevel gear S5053 onto the tail drive cou-

pling, and secure it by tightening the grubscrew S0041
onto the machined flat.
The tail drive coupling should have zero axial play.
- Place the second 20-tooth bevel gear S5053, the spacer
sleeve S5062 and the tail rotor shaft S5063 between the
ballraces S4350.
- Position the tail rotor shaft so that it ends flush with the
second ballrace.
- Fix the bevel gear on the tail rotor shaft by tightening the
grubscrew S0041 onto the machined flat. Grease the bevel
gears.
6.2 Assembling the control bridge
and actuating arm
- Assemble the parts of the control bridge: 2 x S5039,
S5059, S5072, S5054 and S5073. Screw the sliding slee-
ve S5059 into the actuator bridge S5073 to the point
where the control ring S5072 rotates freely but without any
slop.
- Oil the tail rotor shaft lightly and push the control bridge
onto it.
- Press the spacer ring S5060 into the arm on the tail rotor
gearbox housing.
- Mount the actuating arm S5075 on the arm of the tail rotor
gearbox housing using the screw S0114 and washers
S0000. The lever must swivel freely but without slop.
- Push the ring of the actuator arm over the linkage ball on
the control ring.
6.3 Installing the tail rotor hub
- Attach the gearbox cover S5149 to the tail rotor gearbox
housing using the screws S0097 and washers S0000.
- Fit the tail rotor hub S5061 on the tail rotor shaft, set it
flush with the outside end, and tighten the grubscrew
S0041 onto the machined flat to secure it.
- Fit the remaining parts on the tail rotor hub.
- Fit the tail rotor blades together using the 2 Ø x 36 mm
dowel pin, S3499, for balancing.
- Support the rotor blades at the centre.
- The lighter blade will now rise; apply adhesive tape to that
blade until the two blades balance level.
- Fix the tail rotor blades S5070 in the tail rotor blade hol-
ders using the screws S0080, and tighten the screws just
to the point where the blades are still free to swivel.

6.4 Installing the tail boom and the stabilisers
- Slide the tail rotor gearbox into the tail boom as far as it
will go, and at the same time fit the drive shaft S5018 into
the tail rotor drive shaft coupling.
- Secure the drive shaft by tightening the grubscrew S0041
onto the machined flat.
- Attach the vertical stabiliser S5155 to the tail boom using
the screws S0098, washers S0000, vertical stabiliser clips
S5066 and nuts S0010.
- Screw the linkage ball S3150 to the horizontal stabiliser.
- Fix the horizontal stabiliser to the tail boom using the scr-
ews S0074, washers S0000 and the clips S5158 and
S5148.
Stage 7
7 Installing the tail rotor servo
and tail rotor pushrod
- Fix the tail rotor servo to the tail boom support bracket and
the tail rotor servo holder using the plastic oval washers
S5100.
- Clamp the tail rotor servo mount to the tail boom using the
screw S4300.
- Set the tail rotor servo to centre from the transmitter.
- Cut down the servo output device as shown and screw it
to the servo (see Stage 3.2).
- Screw the clevises S0059 to the tail rotor pushrod S5019
(length between clevises 378 mm).
- Connect the pushrod to the outer hole in the tail rotor
actuating lever and the servo output arm, and engage it in
the pushrod guide. Note the 11 mm length of the servo
output arm.
Stage 8
8.1 Installing the cabin holder, receiver and gyro
- Press the cabin holder S5103 into the rear platform.
- Fix the receiver and gyro to the rear platform using double-
sided adhesive tape, No. S5142.
8.2 Installing the speed controller and aerial
- Fix the speed controller to the front platform using double-
sided adhesive tape, No. S5142.
Order No.
