FY-40A Flight Stabilization System

Installation & Operation Manual

Dear Customers,

Thank for choosing FY-40A as your inertial stabilization solution. Please read this manual

carefully before using the system to ensure proper use and operation. If you need any technical

support kindly contact us directly: [e-mail] .

1、Operating Principle And Function

FY-40A 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:

●Mode 1: FY-40A Deactivated Mode In this mode, the FY-40A stabilization function is turned off.

The aircraft is completely under the control of the pilot.

●Mode 2: Auto Stabilization Mode In this mode, the FY-40A will automatically command the

aircraft control surfaces to maintain level flight at all times.

●Mode 3: 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-40A

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.

Attention：When ailerons also were used as the flaps,

Please respectively connect two aileron servos to

AIL1 and AIL2 ports. Make CH6 and AIL channels

linked, also set up a switch to control flap function.

May be only part of the remote control to

support this function. Detailed instructions please

refer to the manual of the remote control.

just use a Y cable to connect two aileron servos

to AIL1 port.
