DoS Flight Stabilization System
Installation & Operation Manual V1.1
Dear Customer:
Thank you for choosing DoS as your autopilot system. Please read this manual carefully before using the system to
ensure proper use and operation.
The installation and use of this device require some skill and knowledge in flying remote controlled fixed wing
aircraft.
 If you are a complete beginner and have never flown one before, we do not recommend you install this device on
your own.
 Please find assistance from an experienced RC pilot who may provide you with the basic knowledge required to use
this device successfully.
 If you are already an experienced flyer, you will find the DoS installation to be easy and logical. Just follow this
manual and you won‟t go wrong.

1. Operating principle :
Attitude Flight Stabilization System (AFSS)
DoS module
DoS is an inertial attitude measurement instrument. Now version V1.1 used for automated stabilization of fixed
wing model aircrafts,but after upgrade firmware can be used for other aircraft and equipment control (For more details of
DoS,please refer to the latest firmware and instrctions)
DoS has integrated three-axis gyro ,three-axis accelerometer,three axis magnetometer and barometric pressure
sensor. DoS can accurately measuring flight attitude, the earth azimuth and through the barometer to measure relative
altitude. Through the sensor measurement data combined with attitude control can realize the Stabilized Mode, 3D Mode,
Return To Launch Mode, Fixed altitude and Heading lock flight Mode, Auto Circling Mode and so on.
GPS module
GPS module enables the DoS to calculate the flight course and exact location of the aircraft. DoS has three
navigation mode :Return To Launch, Auto Circling and Heading lock,You can activate any of navigation modes after
connecting GPS.
Altitude control
DoS use the barometer to measure relative height, through the elevator servo and throttle control to realize the
flying altitude control.
Heading control
Without GPS module,DoS through the three axis magnetometer to measure the heading angle,use the aileron servo
and rudder servo to control flying heading. But will be affected by the wind then deviate from the original route.
After connecting the GPS,DoS receives position and course information to keep straight flying.And DoS will
automatically correct the deviation cause by crosswind.
Speed control
The DoS has some control over the throttle channel after connect GPS module.When flying in Navigation
mode,please ensure the throttle stick control signal is enough.Otherwise you aircraft maybe stall.
2. Function of DoS
The function of DoS without GPS
●Deactivated Mode- In this mode, theDoS stabilization turned off.The aircraft is completely under the control of the
pilot.
●Stabilized Mode - DoS can automatically keep the level flight attitude in any weather condition. This makes operating
the aircraft 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.
