Installation and Assembly
Cabling
Use double-sided adhesive tape to mount the gyro system in
the aircraft. Make sure the HG3XA is firmly attached to the
airplane at your model’s center of gravity and ensure that:
1. The long side of the gyro is parallel to the roll axis of the
aircraft (in the direction of forward flight); and
2. That the gyro is level horizontally with the roll axis of the
aircraft.

Prior to operating your HG3XA for the first time, please review
the instructions and reminders below and confirm that any
rules for use have been met.
· Read this manual in detail and in its entirety. To set-up
your HG3XA, follow the instructions given step-by-step as
described.
· Reset the middle position of the gyro system after installing
the gyro, replacing your remote control system, or re-
adjusting the trimming (sub-trim) of the transmitter. To
do this, toggle the 3-way switch on your remote control
system twice between Standard and Heading Hold mode
for one second. The blue LED will flash rapidly and once the
adjustment has been saved, the blue LED will flash again.
Note: Failure to reset will engage Heading Hold mode
automatically.
· The HG3XA 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
on 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. Wait until initialization has been
completed.
Once you have installed the HG3XA, 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.” Next, connect the servos to the lower row of pins marked
“OUT.” For pin assignment, refer to Chapter 2.
The throttle servo or the electronic speed control
is usually connected to the throttle channel of the
receiver. Note that there is no connection to the HG3XA.
i
If your plane has 2 aileron servos you will connect only
one to the HG3XA and to connect the second servo
directly to your receiver as normal. You can still secure
a potential aileron diff erentiation. The gyro eff ect
around the pitch axis is usually still suffi cient.
