YPICAL PPLICATIONS
Small, light, high-performance Dual-Mode gyro
for stabilising the tail (yaw axis) of electric-
powered model helicopters with rotor diameters
up to 1.30 metres. The gyro is designed exclu-
sively for modelling applications, and must not be
used in man-carrying or industrial equipment.

4.1 Installing the MULTIgyro 300 DP
Vibration may damage the gyro, and can have an
adverse effect on its stabilising effect. For this
reason it must be mounted in a location with as
little vibration as possible. The gyro itself must
also be protected from vibration. For this reason
fix the gyro in place using the two self-adhesive
pads supplied in the set.

SET
1. The gyro should be mounted on a strong
surface at or close to the helicopter's main
rotor shaft where vibration is as low as pos-
sible. The gyro must be installed in a well ven-
tilated position, well away from heat sources.
2. Ensure that the MULTIgyro 300DP is securely
fixed: the mating surfaces must be clean and
free of dust, grease and oil.
! Do not mount the gyro using just one large
adhesive pad which covers the whole under-
side of the device!
! Never use simple double-sided tape without a
foam layer; always use the adhesive pads
supplied in the set.
! The adhesive pads should be checked at
regular intervals, and must be replaced if they
no longer adhere strongly. Use 3 mm thick
foam adhesive pads.
4.2 Connecting the MULTIgyro 300DP
4.2.1 Connections for Single Mode Operation
In Single Mode operation the gyro always works
2.)
in Headlock mode. The gain (gyro sensitivity) is
adjusted on the pot (marked GAIN) on the gyro -
not via the transmitter.
Connections:
Connect the gyro between the tail rotor servo and
the receiver, as shown in the illustration.

- red (+)
- brown or black (-)
The yellow lead with socket is
not used for Single Mode (do
not connect to receiver!)
Connect receiver lead to
receiver (tail rotor servo
channel).
Lead: orange / red / brown
4.2.2 Connections for Dual Mode Operation

Connect receiver lead to
receiver (tail rotor servo
channel).
Lead: orange / red / brown
In Dual Mode the gyro can be set to work in
Headlock or Standard mode. The mode (servo
travel direction) and the gyro gain (servo travel
adjustment) are switched using an auxiliary
transmitter channel.

4.3. Transmitter Settings
1. Switch the transmitter ON.
2. If your transmitter features mixer functions,
switch off any which affect the tail rotor servo
(e.g. throttle / tail rotor mixer, torque compen-
sation, etc.). Set the tail rotor trim on the
transmitter to neutral. Do the same with sub-
trim (servo centre offset), if present.
3. If you are using a MULTIPLEX transmitter, set
servo travel to +/- 70% as a starting point.
4.4 Basic Settings on Gyro and Helicopter
1. Switch the receiver ON.
Do not touch the helicopter until the LED on
the gyro lights up (initialisation complete); this
process takes a few seconds.
2. Tail rotor trim settings:
Connect the pushrod to the servo output arm
(basic setting: servo arm length 10 - 15 mm).
With the servo at neutral, fit the output arm on
the output shaft at right-angles to the case.
Later, during test-flying, you may wish to vary
the output arm length in order to obtain your
preferred set-up in terms of response behav-
iour and rate of angular movement.
Check that the direction of rotation of the tail
rotor servos is correct. If the servo rotates the
wrong way, correct this using the "Servo Re-
verse" function at the transmitter.
3. Dual Mode only (not required if the gyro is
used in Single Mode, since Headlock Mode is
always set in this case):
Identify the switch or slider position on your
transmitter at which Standard and / or Head-
lock mode is active. Observe the behaviour of
the tail rotor servo when you apply full travel
in one direction, and then release the stick:
