FY-DoS Autopilot is aimed specially at beginners willing to improve their flying skills while enjoying
flight safety and ease of operation. It Integrated three-axis accelerometer, three-axis gyroscope,
three-axis magnetometer, high-accuracy barometer. It is more compact and higher stability.Firmware
changing between the fixed wing and the multi-rotors can be realized by the software in our website.
Here is the details for Multi-rotors firmware.
Function on the multi-rotor
upgrade the multi-rotor firmware V2.10 and above can realize the following functions:
● Attitude Stabilized Mode —— DOS can auto stabilize the aircraft flight attitude in this mode, pitch
and roll stick center position for 0 °attitude,its endpoint is 45° , pitch and roll stick can linear control
the flight attitude, maximum angular velocity is 150° / s. Yaw stick in the center position will lock
current course , its endpoint corresponding maximum rotation rate 135° per second, yaw stick can
linear control the aircraft rotation rate. Throttle stick direct control aircraft climb and decline, climbing
and declining rate is directly related to the throttle.
● Hovering Mode —— The GPS Module must be connected to the DOS with at least 5 GPS satellites
detected.In this Mode, yaw control method is the same as Attitude Stabilized Mode.DOS can auto control
flight altitude.Climbing and descending rate is directly related to the throttle, when the throttle stick is in
the center position,DOS auto locks the altitude, in maximum means climb rate is 3 m/s, in minimum
means decline rate is 1.5 m/s.Throttle stick can linear control the aircraft climb and decline rate.Pitch,
roll sticks released will lock the position when GPS signal is adequate. And non-releasing is stand for
the aircraft movement speed in the corresponding axial direction(Maximum 6m/s),not aircraft attitude.
● Auto Return To Launch Mode(RTH) —— The GPS Module must be connected to the DOS with at
least 5 GPS satellites detected. In this Mode, DOS is take over all the control, the RC aileron, elevator,
throttle and rudder stick is no control function anymore. When you switch into RTH mode, DOS (DOS
has 20m altitude protection limit, if the switch point altitude below 20m, DOS will automatic climb to 50m)
will first automatic adjust the aircraft heading to the home point and automatically fly the aircraft back to
the take-off point, while maintaining altitude. Upon reaching the launch area, the unit will automatically
landing and closed the engine.
● Camera Gimbal Stabilization —— DOS multi-rotor firmware,when is used to control the aircraft under
6 axis, can simultaneously control two axis Camera Gimbal Stabilization.
● First Person View (FPV) —— Can be connected to the Hornet - OSD, the flight data overlay 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, Hovering and Auto Return To Launch.
● Real time telemetry —— Real time telemetry-real time monitor the flying state, using the Data Radio
to lengthen the remote control distance.
