NO.5 software system
Mdcockpit cockpit instrument software based on Microsoft Windows TM operating system integrates many functions such as flight planning, flight monitoring, flight data analysis and so on. Downlink decoder can receive and display various flight data of the aircraft in real time, including battery voltage, coordinates, altitude, direction, attitude, flight time, flight speed, flight path, distance from the takeoff point, ambient temperature, wind speed, motor working state, remote control signal strength, GPS status and other important information. The flight data playback system can simultaneously save all flight data for post flight data analysis. Even in the manual remote control flight mode, as long as the system is equipped with electronic map or image map data of the current operation area, the system can display the position of the aircraft on the map in real time. Waypoint software may help you create detailed flight route planning with the help of waypoint planning editor, so that the aircraft can automatically fly according to your planned route. In addition to planning flight routes, a variety of shooting plans can also be set, such as fixed-point 360 degree panoramic shooting, surround shooting around fixed-point targets, fixed distance along the flight route, and fixed-point shooting.
NO.6 Training machine
Md4-1000 training aircraft adopts semi carbon fiber open and easy to repair structure design, including flight control board, navigation version, IO board, four 250W external rotor brushless motors, tightly integrated GPS / INS, including three-dimensional magnetometer, 2.0B can bus support, folding arm, front and rear rotors X2, left and right rotors x2 and landing gear. The flight characteristics of the training aircraft are very similar to those of the equipment aircraft, but the cost of structural parts is low and easy to repair and replace. It can be used for operators to master the remote control control flight and carry out special flight skills training at the beginning stage, which can reduce the cost of daily training loss and reduce the psychological pressure of operators.
