For this reason if you are using a Graupner radio control system we recommend that you start
by programming the “throttle limiter” function at the transmitter. If you then close the throttle lim-
iter, the motor cannot start running even if you advance the throttle stick accidentally.
Before you connect the flight battery for the first time please ensure that you are holding the
model firmly in a position where the main and tail rotors are free to rotate, so that no damage
can occur even if the motor should start running.
First switch the transmitter on, set the throttle control to “motor stopped”, then connect the flight
pack: the next step must be to program the speed controller in accordance with the instructions
supplied with the unit.
When you have completed this procedure, and are confident that the motor will reliably remain
switched off, the next step is to set up the swashplate and tail rotor control systems correctly.
With the throttle limiter closed, move the collective pitch stick to centre: the swashplate should
now be exactly horizontal when viewed from all sides, and should be close to the centre of its
vertical range of travel. If necessary, adjust the links connecting the servos to the swashplate by
screwing the ball-links in or out on the threaded pushrod ends. The servo output arms should be
exactly horizontal at this point.
Checking the control system:
The main rotor plane, and with it the entire model, tilts in the same direction as the swashplate.
Move the stick forward (forward cyclic / down-elevator), and the swashplate should respond by
tilting forward. Pulling the stick back (back cyclic / up-elevator) should cause the swashplate to
tilt in the opposite direction. The same applies to the roll control system: the swashplate must tilt
in the direction corresponding to the movement of the cyclic roll control stick on the transmitter
(normally the right primary stick).
The collective pitch control system behaves in exactly the opposite manner: if the swashplate is
moved axially
downward
, the model
climbs
; if it is moved
up
, the helicopter
descends
. This ac-
tion, which is carried out by all three swashplate servos working together and in the same direc-
tion, is controlled by the throttle / collective pitch stick on the transmitter (normally the left-hand
primary stick), which is generally fitted with a ratchet for this purpose.
This collective pitch control system (collective rotor blade pitch control) should now be adjusted
in such a way that the main rotor blades exhibit a positive pitch angle of 0°, i.e. they should be
exactly horizontal when the stick is at centre. This setting is altered by adjusting the short push-
rods which run upward from the rotor blades to the mixer levers; at the same time the flybar
must be kept exactly horizontal, i.e. at right-angles to the main rotor shaft.
Once these basic mechanical settings have been established, the collective pitch range can be
set up at the transmitter for normal flying: set the collective pitch curve in the helicopter mixer in
such a way that the rotor blades exhibit a positive pitch angle of about 3° ... 5° when the collec-
tive pitch / throttle stick is at centre; at “full-throttle / full collective” the angle should be 7° ... 10°,
and at the bottom end-point of stick travel 0° ... -3°. The easy method of setting these values ac-
curately is to use a rotor blade pitch set-up gauge; however, in most cases it is adequate to es-
timate the values, as they have to be fine-tuned in flight in any case.
The final stage of the initial set-up procedure is to check that the tail rotor control system oper-
ates in the correct “sense” (direction of response): if you look at the pitch angle of the tail rotor
blades from above, it is easy to see the direction in which the tail is pulled when the tail rotor is
spinning, and therefore the direction in which the model rotates around its vertical (yaw) axis. If
you move the tail rotor stick to the right, the model (i.e. the helicopter’s nose) must rotate clock-
wise when viewed from above; move the stick to the left, and the helicopter should turn anti-
clockwise; if this is not the case, correct it using your transmitter’s servo reverse facility for
channel 4.
The flight battery, which in some cases also provides power to the receiving system via the
speed controller’s integral BEC circuit, is connected to the controller by a plug and socket. This
connection should be positioned for easy access, because it serves as the ON / OFF switch for
the receiving system, as well as acting as the flight battery charge socket.
The flight battery is installed at the top of the chassis at the front, where it is secured using the
Velcro (hook-and-loop) straps supplied; its position should be adjusted so that the Centre of
Gravity (directly below the main rotor shaft) is correct when the canopy fairing is fitted.
