Product 18/21



DoS is an aeromodelling balancing instrument designed for a variety of platforms. It is aimed specially at beginners willing to improve their flying skills while enjoying flight safety and ease of operation. It Integrated 10 degrees of freedom sensor?including three-axis digital accelerometer ?three-axis digital gyroscope?three-axis digital magnetometer?high-accuracy barometer. It is more compact and higher stability.

Not only it boasts auto-stabilization flight feature and 3D flight mode, but also acts as autopilot which has the functions of auto return to home, fixed altitude flight and heading lock as well as automated circling if connected with GPS module.
DoS could be connected to Hornet FY-OSD for FPV flight, connected with data link and used GCS to achieve flight control and data monitor.Using DoS stabilizer, you can improve your own flight level quickly, enjoy your flight in the air with greatly reduced possibility of losing and crashing plane.



DoS work alone function


    Deactivated Mode- In this mode, all control of the aircraft is by the pilot. The DoS does not participate in flight control. equivalent to ordinary RC remote control.


    Stabilized Mode - DoS can automatically keep the level flight attitude in any weather condition. This makes operating the aerobat become very simple and easy for the beginner. When the pilots feel the plane out of control as long as stabilize the flight throttle, loosen the operating sticks, it can automatically recover to the level state.


    3D Mode - Help stabilize flight attitude, will try its best to keep loosen sticks attitude flight, make the flight more smooth, easy to do all kinds of special action.


    Fixed altitude and Heading lock flight Mode - can lock the flight course and maintain the flight height. Loosen the operating stick; the plane can automatically keep flight course, at the same time lock flying height, automatically correct flight course deviation, easy to operate.


    Auto Circling Mode -Plane will keep the current height, at a certain turn rate hovering flight (look up, a counterclockwise circle), but it will not hover around a fixed point, and may be away from the original hovering point because of the wind.




DoS connect with GPS module function


    Fixed Altitude And Heading Lock Flight Mode - Can lock the flight course and maintain the flight height. Loosen the operating sticks; plane can automatically keep flight course, at the same time lock flying height, automatically correct flight course deviation, and begin straight line flight. Easy to operate.


    Auto Return To Launch Mode(RTH) - In the Auto Return To Launch Mode, aerobat will automatically return to the course reversal point, keeping the current height, and it will hover after arriving the target point.


    Auto Circling Mode-When activated in this mode, the plane will immediately fly in a circle( look up , clockwise hovering). The centre of the circle is the point of activation.The plane will hover keeping the current height, The hovering radius can be set, and the default circle radius is 80 meters.


    GCS Software –Operator can set flight parameters, monitoring and recording flight path etc through the GCS software in the computer(This requires connecting the data radio) .


     New function:

    Flight Fencing –Can set distance when is in recerceicer remote control, if your plane goes outside the fenced area then it will auto switch to GUIDED mode, and will fly back to a pre-defined return point and loiter there ready for you to take over again. You then use a switch on your transmitter to take back control .

DoS can connect with the Hornet FY-OSD and the Data Radio


    DoS has one UART interface for connecting the FY-data radio and the OSD module. It can realize the following function by combing them.


    First Person View (FPV) - Can be connected to the Hornet FY-OSD, the flight data stack to video output,and through the vodeo transmission system to send back, let you enjoy the fun of FPV. And it will be easier to operate FPV with the functions of automatic balance, Fixed altitude and Heading lock flight and Auto Return To Launch.


    Real time telemetry-real time monitor the flying state, using the Data Radio to lengthen the remote control distance , and you can change the flight height and flight parameter through the Ground control system(GCS).


In the video can be shown on the flight attitude, flight speed, position, altitude, flight time, distance, working mode, the battery voltage, current, power consumption etc. More information please refer the Hornet FY-OSD.


Monitoring flight path through GCS software
