FY-30A Flight Stabilization System
installation & operation manual
Dear Pilot,
Thank for choosing FY30A as your inertial stabilization solution.
Please read this manual carefully before using the system to ensure
proper use and operation.
Note:
The installation and use of this device require some skill and
knowledge in flying remote controlled fixed wing aircraft.
If you are a complete beginner and have never flown one before, we
do not recommend you install this device on your own.
Please find assistance from an experience RC Pilot who may provide
you with the basic knowledge required to use this device
successfully.
If you are already an experienced flyer, you will find the FY30A
installation to be easy and logical. Just follow this manual and you
won’t go wrong.
If you need any technical support kindly contact us directly:

INTRODUCTION
FY-30A is an inertial attitude measurement instrument used for
automated stabilization of fixed wing model aircrafts and two axis
camera gimbals.
FY30A has an integrated three-axis gyro and three-axis
accelerometer which controls the aircraft movement in
three-dimensional space. By using your remote control, the unit can be
turned on or off for the following functions:
Level flight – When stabilization is activated, the FY-30A
will automatically control the aircraft for smooth easy flying. For
beginners in RC aircraft flying, this is advantages as it makes flight
easier and increases the student pilot self-confidence. The system can
be activated throughout the entire flight duration, from take off to
landing.
Emergency Recovery - If you lose orientation or feel the
plane out of control, then release all control sticks, maintain throttle
and switch on the FY30A. The unit will automatically send the correct
signals to balance of the aircraft and regain level flight.
Aerobatics – for the experienced fixed wing 3D pilot, the
FY-30A can help you achieve a more accurate flight path, especially in
windy conditions. FY-30A makes 3D maneuvers such as inverted flight,
knife-edge, crane etc easier and simpler to achieve and maintain. A
great way to practice and improve your 3D flying.
First Person View - for long-distance RC flight via video
transmitter, the FY30A will maintain the balance of your aircraft. You
only need to control the heading of your aircraft and enjoy the view.
Firmware upgrade – The FY30A firmware is upgradable
by connecting to your computer via a USB TTL cable. As Feiyu Tech
continuously improves the FY30A system, firmware upgrades will be
released periodically.

RC Radio suitability:
The FY-30A has been tested to work well with the following RC system:
Robbe-Futaba PPM / PCM 1024 / PCM G3 mode, 2.4G systems;
Graupner / JR PPM 8, PPM 12, SPCM mode;
MPX PPM8, PPM 12 with UNI mode;
Any other system with a neutral position of 1.5 ms (standard in most RC
Radios).
FY-30A Operating Mode
The FY-30A can be operated in three flight modes:
Mode 1: FY-30A Deactivated Mode. In this mode, the FY-30A
stabilization function is turned off. The aircraft is completely under the
control of the pilot.
Mode 2: 3D Control Mode. In this mode, the balancer utilizes its
3-axis gyroscope to sense roll velocity and flight attitude. If no input is
given by the pilot (sticks in the middle position) the FY30A will lock the
current aircraft attitude. This prevents rolling of the aircraft at the axial
plane and maintains its current posture. Therefore the aircraft can be
easily maneuvered to complete a variety of 3D flight with added
stability and smoothness.
Mode 3: Auto Stabilization mode. In this mode, the FY-30A will
automatically command the aircraft control surfaces to maintain level
flight at all times.
Switch Setting for FY-30A Flight
Modes
a) To activate the different flight
modes, use a free Receiver channel (e.g.
Channel 5) to output the appropriate signal
to the FY30A.
b) Use a 3 way-switch from your
RC radio as in the example at right:
How it works
The core of the FY-30A is the integrated 3-axis gyro and 3-axis
accelerometer which is the basis for its inertial sensing. The FY30A is
an inertial navigation platform with a strap down attitude algorithm
designed for fixed wing aircraft stabilization.
When the FY-30A is in auto-balance mode, it detects the aircraft
attitude and horizontal positioning and issues commands to servos that
adjust the aircraft control surfaces (Aileron, Elevator and Rudder) so
that the aircraft remains level at all times. Due to this autonomous
action to maintain smooth level flight, the FY-30A makes flying very
easy.
When the FY-30A is operating in 3D mode and the aircraft is in an
acrobatics flight, the FY30A will use the 3-axis gyroscopes to calculate
roll velocity and overall flight attitude. With this data, the system
outputs control corrections to maintain smooth aircraft attitude even
when doing aerobatics flight.
Since the FY30A is self contained, it can be used in all weather
conditions, indoors or outdoors. Just power up and take off.
Aircraft Suitability
The FY30A can be used in the following fixed wing models:
Traditional layout fixed-wing aircraft with
c) You may use a 2-position switch, setting the maximum and
minimum End Points (EPA) to activate or deactivate flight stabilization
(omitting 3D-Mode).
d) If you do not connect the Switch channel to your RC
Receiver or the FY-30A does not detect any incoming signal through
this input channel, it will automatically engage Mode 3- Auto
Stabilization Mode. However, we do not recommend flying the unit with
no signal input to the Switch Channel.
e) Please note that even though there is a Throttle Input and
Throttle Output from the FY30A, the system does not overlay any
servos control quantity. As to say, the FY-30A is just used for signals
connecting. As a pilot, you must always ensure your aircraft has enough
cruising speed to prevent stall.
f) Warning: The Auto Stabilization Mode will provide a
smoother leveled landing for your aircraft. However, note that the
turning radius is larger when in this mode. Please ensure your landing
area has adequate clearance for this larger radius.

You will notice the red light blink at
two different rates (or turns off). Gyro
re-setting is complete. Disconnect
power, unplug the jumper and keep it
in a safe place for future use).
NOTE:
Carry out this re-setting procedure only if the 3 conditions (above)
occur. It is not recommended to regularly reset the gyro. It is not
necessary.
The stabilizer unit does not need to be in a horizontal position
during initialization. However, you must ensure there is no vibration
during this process. If you suspect shaking had occurred, just restart the
resetting process.
FY30A power supply
FY30A working voltage = 5 to 6V.
The FY30A require stable power input. Therefore, we highly
recommend using an External BEC power supply with minimum 3A
output. The higher the better.
Be sure to remove the Red wire from your ESC plug if using an
external BEC.
BEC should be plugged into your RC Receiver. Power is sent to
the FY-30A via Channel 1 input.

Gyroscope initialization (re-setting):
Out of the box, the FY-30A has been fully initialized. However, if the
following conditions occur, resetting the gyro is recommended:
1. The device has not been used for a long time.
2. There is a change in environmental temperature of over 30 degrees.
3. When the red LED light flashes even when the aircraft is stationary.
Initialization / Reset Procedure
Install the jumper as shown in this picture:
Power-ON the FY-30A and keep it stationary for at least 20 seconds.
