    Features:

    THIS IS FY91Q MODULE ONLY, THE GPS & COMPASS MODULE MENTIONED IN THE FEATURE SECTION MUST BE PURCHASED SEPARATELY.

    FY91Q MULTI ROTOR SYSTEM
    Basics on how the system works:
    · Inertial Stabilizer: The FY91Q utilizes an attitude flight stabilization system (AFSS)
    which is inertial sensing based. The system also incorporates autonomous positioning
    and flight control.
    · The FY91Q AFSS integrates a three-axis gyroscope combined with tri-axial
    accelerometers to sense and create a drift-free 3 dimensional stabilization system.
    · The FY91Q also utilizes GPS and barometric pressure sensing to obtain accurate
    aircraft positioning and altitude.
    · By combining sensor data from the gyros and accelerometers, together with altitude
    and GPS positioning, an accurate inertial navigation and autopilot system is formed.
    Fixed positioned and altitude hover and return to home is just a switch away.
    · As this product is still under intense Research and Development, FeiYu Tech has
    enabled firmware upgrading via a USB-TTL Connector. As new algorithms are
    developed for the autopilot system you can download the upgraded firmware from our
    website.
    Barometer and GPS & COMPASS module
    v FY-91Q control module incorporates an accurate barometric pressure sensor. At
    start up, the take-off point air pressure is measured, providing the autopilot with an
    accurate relative height data.
    v The GPS & COMPASS MODULE (to be purchased separately)
    consist of a three-axis magnetic sensor and high sensitivity GPS receiver. This
    module enables the autopilot to sense the flight course and exact location of the
    aircraft.
    v Note that if the FY91Q is not connected GPS & COMPASS module, it will
    function as purely as a flight stabilizer for multi rotor aircraft. The Autopilot system
    cannot be engaged.
    v For the autopilot to function, the GPS Receiver must detect at least 5 satellites.

    Autopilot Function
    The current FY91Q firmware supports two autopilot functions; fixed altitude Auto Hover
    and automated Return to Home. To enable autonomous flight, the GPS & Compass
    module must be connected to the FY91Q.
    · Auto Hover
    o 3 dimensional GPS positioning is used to automatically maintain aircraft
    hover position and altitude.
    o Accuracy of hover position (range) depends on wind conditions and speed.
    o When throttle is increased the altitude of the aircraft will increase. If the
    aircraft is moved to another location (via AIL or ELE), upon releasing the
    control sticks the aircraft will automatically hold position and hover in the
    new location.
    · Automated Return to Home
    o By utilizing GPS positioning, the autopilot will return the aircraft to the
    starting point upon activation of the RTH Mode.
    o Upon reaching the starting point (home) the autopilot will activate Hover
    Mode, maintaining position and altitude while waiting for your further
    instructions.
    o To establish the Home point, a minimum of 5 GPS satellites much be
    detected.
    ON SCREEN DISPLAY and DATA RADIO
    a. The FY91Q supports OSD data output via UART interface.
    b. By connecting this interface to the AP117 OSD, telemetric data such as GPS, flight
    navigation, AHI and autopilot modes can be displayed on your downlink video.
    c. The UART Interface can also be connected to the FY-606 digital data radio system,
    which establishes a bi-direction radio communication between the FY91Q and your
    portable computer.
    d. By uploading our Ground Control Software (GCS) (free from our website), you can
    monitor your flight on the GCS map, display on-board telemetry data and control the
    aircraft flight path via the click of your mouse.
