FY-901 Flight Stabilization System

installation & operation manual

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: service@feiyu-tech.com.

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.

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.

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: service@feiyu-tech.com.

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:

Gyroscope initialization (re-setting):

Out of the box, the FY-901 has been fully initialized. However, if the following

condition occurs, resetting the gyro is recommended:

1. The device is kept unused for a long time.

2. There is a change in environmental temperature of over 30 degrees.

3. 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-901 and keep it stationary for at least 20 seconds. You will

notice the red light blinks at two different rates (or turns off). Re-setting of Gyro is completed. 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 condition (above) occurs. 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 has occurred, just restart the resetting process.

FY-901 power supply

X-Type Layout

Cross Type Layout

 FY-901 working voltage = 5 to 6V.  The FY-901 requires 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-901 via

Channel 1 input.

 FY -901 colour coded cable to RC Receiver:

RC Receiver Requirement

a) FY-901 requires at least a 5-channel receiver

b) Plug in the cable into the FY-901 and connect to the RC Receiver following

these colour codes:

c) Note Channel 5 will output the signal to control the 2 flight modes of the

FY -901. Therefore assign 2-way switch to this channel.
