Calibrating the Compass

When the app prompts that compass calibration is required, tap
Settings, then Sensors. Tap Calibration in the compass calibration section, then follow the on-screen instructions.
DO NOT calibrate your compass where there is a chance of strong magnetic interference. This includes areas

where there are utility poles or walls with steel reinforcements.
DO NOT carry ferromagnetic materials with you during calibration such as keys or mobile phones.

Calibrating the Flow Meter
Make sure to calibrate the flow meter before your first operation. Otherwise, the spraying performance may be adversely
affected.
A. Preparation before calibration: Discharging the bubbles in the hoses
Fill the spray tank with approximately 2 L of water.

Discharging the Bubbles in the Hoses
The T20 features an automatic bubbles discharge function. When it is necessary to discharge bubbles, press and hold the
spray button for two seconds. The aircraft will discharge automatically until the bubbles are fully discharged.
5. Flight
In the app, go to Operation View. Make sure that there is a strong GNSS signal, and the system status bar indicates Manual
Route (GNSS) or Manual Route (RTK).* Otherwise, the aircraft cannot take off.
It is recommended to create a plan for a field and select an operation to enable the aircraft to take off and perform the
operation automatically. Refer to the Starting Operations section for more information. In other cases, take off and land
manually.
Takeoff
Perform a Combination Stick Command (CSC) and push the throttle stick up to take off.
Landing
To land, pull down on the throttle stick to descend until the aircraft touches the ground. There are two methods to stop the
motors.
Method 1: When the aircraft has landed, push and hold the throttle stick down. The motors will stop after three seconds.
Method 2: When the aircraft has landed, push the throttle stick down, and perform the same CSC that was used to start the
motors. Release both sticks once the motors have stopped.
* RTK positioning is recommended. In the app, go to Operation View, tap
method for receiving RTK signals.
