6.2.7 Flight Calibration
1）
Voltage Calibration
The main battery voltage detected by the flight control system may deviate from
the actual battery voltage. At this time, you need to calibrate the voltage. Fill in the
real battery voltage on the "Real Voltage" of "Flight Calibration" page, and then tap
"Calibrate" to complete the voltage calibration.
2）
Horizontal Calibration
Since there may be some deviation between the plane of flight control installation
and the plane of UAV body, horizontal calibration is required, otherwise the flight
performance will be affected. Place the UAV on a horizontal plane, if the angle of the
UAV has a deviation of more than 2 degrees, horizontal calibration is required. Enter
"Advanced" > "Flight Calibration" > "Confirm", then you will find that the previous
angle deviation will be cleared. The horizontal calibration is completed.
6.2.8 Preliminary Parameter Setting
Parameter setting is very important, setting error will directly lead to crash accident.
Enter "Advanced", select the four-axis X-shaped plant protection UAV model on the
machine model setting page; enter "Algorithm", and ensure that the flight control
installation mode is consistent with the actual installation. For the "Noise Suppression",
you can select default 3 before the first flight; the GPS installation deviation is the distance
from the GPS installation position to the UAV center: for X-axis, right is positive; for Y-axis,
front is positive; for Z-axis, up is positive
