6.2 Cabling

Use double-sided adhesive tape to mount the gyro system 
MULTIGyro G3 in the aircraft. Make sure the gyro system is 
firmly attached at the following points:

·  Attachment near the centre of gravity of your model.
·  Make sure the long side of the gyro is parallel to the roll axis 

of the aircraft, i.e. in the direction of forward flight (Fig. 1).

·  Horizontally level MultiGyro G3 corresponding to the roll axis 

of the aircraft (Fig. 2).

·   Make sure your model has been assembled correctly prior 

to use.

·  Read this manual carefully prior to start-up and install your 

MULTIGyro G3 step-by-step following all the instructions in 
this manual.

·   Reset the middle position of the gyro system after installing 

the gyro, replacing your remote control system or re- 
adjusting the trimming (sub-trim) within the transmitter. The 
servos will otherwise change automatically to the Heading 
hold mode. To do so, toggle the 3-way switch on your remote 
control system twice between Standard and Heading hold 
mode within one second. The blue LED flashes rapidly for 
approx. one second during this process. Once the middle 

adjustment has been saved, the blue LED starts to flash 
again.

·   The gyro system MULTIGyro G3 contains mixing functions 

for flying wing and delta wing aircraft as well as aircraft with 
a V-tail. If one of these mixing functions (aircraft types) is 
selected at the gyro, neither a V-tail nor a delta wing mixer 
can be activated or used at the transmitter.

·   The blue and red LEDs flash rapidly for three seconds after 

switching on the gyro system. Do not move your model during 
this period and wait until initialisation has been completed.

Once you have installed MULTIGyro G3, connect the channels 
of the aileron, elevator and rudder from the receiver and the 
3-position switch function to the upper row of pins marked "IN".

Now connect the servos to the lower the row of pins marked 
"OUT". 

For pin assignment, please refer to Chapter 2.

The gas servo or the flight control system is usually 
connected to the gas channel of the receiver, there is 
no connection to MULTIGyro G3!

You can also choose to control just one aileron servo 
via MultiGyro G3 and to connect the second one directly 
to your receiver as normal. You can still secure a potential 
aileron differentiation. The gyro effect around the pitch 
axis is usually still sufficient.
