FCR5 update content

1. Add 4 amplitude propellers sandwiched between the 8 main propellers to separate and control throttle valves, roll, and pitch.

2. Optimize the PID descent speed.

3. Repair the crash caused by vibrations during takeoff.

4. Add height protection, set the pitch angle to negative 2 degrees when it is 22 meters below the set height.

5. Significantly improve stability (major updates)

Instructions for use

Slider 1 controls the cruise altitude, and when the battery is low, it will automatically descend. You can only turn on AG1 for semi-automatic descent, while slider 2 can control the speed of descent. During the entire ascent flight, there is no need for any operation. During the level flight, you only need to control pitch and roll to control speed and direction. Finally, when landing, you only need to adjust the attitude. The door is opened with slider 3. The maximum cruising altitude is 1000m above sea level, with an error of about 22m. After landing, it is necessary to manually reset slider 1 to zero.
