Note: Under normal circumstances, a single shot can trigger the motor sequence detection. If the position is not accurate, you need to repeat step 2 to start the four shots.
2) .Motor direction test
After unlocking, the aircraft propellers run at low idle speed evenly. The four channels of the remote control can determine whether the steering is reversed. For example, the idle stick is pushed forward, the propeller behind the aircraft rotates, and the propeller in front of the aircraft stops. Similarly, when the left fly rod is pressed, the aircraft is left. The propeller on the side stops and the propeller on the right side of the aircraft rotates.
5. Remote control runaway protection
First of all, you need to set the remote controller out-of-control protection correctly in the basics of the assistant software-> remote control interface. When the GPS satellite signal is good, if the receiver signal is lost, no matter which flight mode the aircraft is in, the flight controller will perform the out-of-control protection behavior. If the remote control signal is restored and you want to control the aircraft again, you need to switch the flight mode channel back and forth to gain control.

Flight Mode Introduction

1. Attitude mode
Attitude mode is suitable for returning to the central control user. IMU, GPS, magnetic compass and barometer participate in the flight. The attitude mode can automatically switch the control mode according to the GPS signal. If there is no GPS or the signal is not good, you can use fixed altitude flight. If the GPS signal is good, you can set the fixed altitude. There is no imitation function in the attitude mode.
1). Working conditions
Since the attitude mode requires the GPS module to participate in the work, it must wait for the satellite search to complete and the positioning accuracy to meet the requirements. As shown in the figure below, when the LED indicates that the GPS status is normal GPS signal, GPS signal is good, or RTK positioning, you can unlock or enter this mode in this mode.

k v2 Working conditions - JIYI K++ V2 Flight Controller Manual

Step 3: Record point A
Hover in AB operation mode and dial the AB record control lever to the second gear. After the recording is completed, the LED flashes yellow for 2 seconds.
Step 4: Record point B
Hover in AB operation mode and dial the AB record control lever to the third gear. After the recording is completed, the LED flashes green for 2 seconds.
Step 5: Choose a direction
Select the direction by turning the roll lever. Move the roll lever to the left to move to the left, and move the roll lever to the right to move to the right. The premise of performing this step is that the last recorded AB point has been cleared, otherwise the step will be skipped and continued according to the last AB job.
Step 6: Continue spraying at the breakpoint
Under the premise that the AB point record is not cleared, switching to the AB operation mode will continue the operation of the last stop of the drug point and direction.
The remote control can manually control the aircraft during AB operation.

After the star search is completed and the positioning accuracy reaches the requirements (the red LED does not flash or the red light flashes only once), the flight controller will automatically record the current position as the home point each time the user unlocks. After entering the auto return mode, the green LED flashes quickly.
2). Operating instructions
The auto return mode can be triggered by the joystick or by runaway protection. When the remote control CH6 mode switch is set to the one-touch return position or the flight control enters the out-of-control protection, if the aircraft is more than 2 meters away from the return point, the aircraft will automatically rise to the set altitude (if the current altitude is greater than the set return altitude, press Return to current altitude). After reaching the return point, the aircraft will first hover in the air for about 3 seconds and then land slowly. At this time, the flight status of the aircraft can be controlled by the remote control joystick (but the throttle lever does not work), making it easier for the aircraft to find a more suitable landing. point. After the aircraft has fully landed, the aircraft will automatically lock. If the aircraft is less than 2 meters from the home point, the aircraft will land in place and lock automatically.
Precautions:
The premise of automatic return is that the return point of the aircraft has been recorded. If you need to use the automatic return, please unlock it after the GPS search is completed. Please refer to the appendix LED three-color light for status and meaning.
When the aircraft is close to people, it is recommended not to switch to the auto return mode to avoid accidents.
