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, pitch, roll, 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,non-released will equivalent of Attitude Stabilized Mode. 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, pitch, roll, yaw and altitude control method is the same as Hovering Mode. Pitch, roll sticks released will automatically fly the aircraft back to the take-off point, Maximum return to home point speed: 5.5m/s.Camera Gimbal Stabilization - DoS multi-rotor firmware,when is used to control the aircraft under 6 axis, can simultaneously control two axis Camera Gimbal StabilizationFirst 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 monitor: - Real time telemetry-real time monitor the flying state, using the Data Radio to lengthen the remote control distance.
