Description:

The FY-20A is a flight stabilizer for fixed wing aircraft based on inertial motion sensing. It utilizes a 3-axis gyroscope and 3-axis accelerometer to control the aircraft attitude in all 3 dimensions. The unit can be activated or de-activated via a spare channel from your receiver. Functions include:

Level flight – when you need it,the FY-20A will automatically level the flight attitude of your aircraft. If you are just learning to fly, this will help you gain experience, log more flying time and increase your confidence. The FY-20A can be left activated throughout the flight duration, from take off until you landing.
Emergency Recovery – in case you lose orientation or you feel the aircraft is out of control, activate the FY-20A via the switch and release of the control sticks. The FY-20A will automatically bring the plane back to level flight.
Precision Flying: For experienced pilot, FY-20A can help you achieve more leveled and precise flight paths, especially when flying and landing in strong wind.
First Person View (FPV): For long distance flying or FPV, the FY-20A will take on the job of leveling the plane for you. Just point the plane where you want to go and enjoy the view!

System Working Principle
The Flight Stabilization System (FSS) in the FY-20A is an integrated 3-axis gyroscope and 3-axis accelerometer. This forms a comprehensive inertial based navigation platform that calculates 3D flight attitude using proprietary FeiYu Tech algorithm.
When activated in Balanced-Mode, the FSS detects any changes to the model’s horizontal attitude. If attitude change is detected, the unit will send out controlling signals to the plane’s ailerons, elevator and rudder to counter that change.
By continuously doing this, the plane is kept in a state of equilibrium, resulting in a smooth level flight. The aircraft pitch attitude (nose up or down) is automatically controlled via the elevator, while aircraft roll is controlled through the ailerons. Flight direction to the left or right is automatically corrected via the rudder servo.
To achieve level flight, the pilot need only release the flight control sticks (aileron, elevator, rudder) so that they return to the transmitter neutral (middle) position. The model will immediately revert to level flight.
When used in the 3D-Mode, if an aircraft is in an acrobatic flight, the activated FSS will automatically counter the rolling speed detected by the 3-axis gyros using all 3-axis controls (rudder, aileron and elevator). The plane will therefore maintain its last attitude state.
The FY-20A can be used in any environment both indoors and outdoors, and in any weather condition. After installation, it does not need any other initialization. Just switch on the power and your plane can take off in stable flight.

Application
The FY-20A can be installed in the following aircrafts:
Normal / Traditional fixed-wing planes
Delta-winged plane with rudder
Delta-winged plane without rudder,
Plane without aileron,
V –tail plane with aileron
V –tail plane without aileron
