When installing the flight controller for the first time, you don't need to consider shock absorption, and use thicker and soft double-sided tape to stick the flight controller to the center of the body. Install the flight control position to avoid the power supply wiring surrounding it, forming a closed loop. After installing the flight controller, complete the flight controller calibration according to the instruction manual, including sensor calibration, remote control calibration, flight mode setting, etc. After the calibration is completed, shake the attitude of the agricultural spray drone and adjust the direction of the drone's nose, and check whether the flight control measurement feedback is correct through the ground station. In addition, after searching for GPS outdoors, observe whether the number of stars is stable. Observe that when the crop spray drone is placed stationary on the ground, the ground station displays whether the ground speed and vertical speed measured by the flight control are correct, whether there is a large jump, and whether the altitude value is stable and correct. If the above conditions are correct, it indicates that the sensor is calibrated correctly and the flight control is in good condition.
