FY-901 Flight Stabilization System
installation & operation manual
Dear Pilot,
Thank you for choosing FY-901 as your inertial stabilization solution. This
manual mainly introduces FY-901 firmware for Multi-rotor flight system.Please read
this manual carefully before using the system to ensure proper use and operation.
Note:
To set up and use of FY-901 in multi-rotor flight require a certain degree of
multi-rotor flight and RC experience.
If you have never flown a multi rotor aircraft before, we recommend that you
don’t install this equipment on your own. Please seek assistance from an experienced
RC multi-rotor pilot.
If you are already an experienced multi-rotor pilot, you will find the installation
simple. Please follow the instructions as stated in this manual and you won’t go
wrong.
Remember, SAFETY ALWAYS FIRST.
If you need any technical support, please feel free to contact us:
INTRODUCTION
FY-901 has integrated three-axis gyro and three-axis accelerometer, which
controls the aircraft movement in three-dimensional space. FY-901 can be used in
multi-rotor copter.
Aircraft Apply
The FY-901 for multi-rotor copter can be used in the following models:
Quadcopter X-Type
Quadcopter cross-Type
Y3-copter
Any other configuration apply need, please e-mail us: [email protected].
RC Radio suitability
:
The FY-901 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).
The FY-901 Operating Mode for multi-rotor copter supports two flight modes :
Mode 1: Auto-Stabilization mode. In this mode, the FY-901 will automatically
command the control surface of the aircraft to maintain level flight all the time(sticks
in the middle position). The sticks correspond the roll and pitch attitude angle.The
netual position of sticks is 0 degree and the maximum angle is 55 degrees.
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 FY-901 will lock the current aircraft attitude. This
prevents from 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
movements with added stability and smoothness.
Switch Setting for FY-901 Flight Modes
To activate the different flight modes, use a free Receiver channel (e.g. Channel 5) to
output the appropriate signal to FY-901.
a)
Use a 2 way-switch from your RC radio as in the example below:
RC Receiver Signal output
b) If you do not connect the Switch channel with your RC Receiver or FY-901 does
not detect any incoming signal through this input channel, it will automatically
engage Mode 1- Auto Stabilization Mode. However, we do not suggest flying the unit
with no signal input to the Switch Channel.
c)
Please note that even though there are Throttle Input and Throttle Output from
the FY-901, the system does not control the Throttle to hold the altitude, you must
always control the Throttle to keep flying altitude.
