Under the normal electrical supply and immediate conditions, this controller can meet crop protection, mapping, aerial photography and other purposes.
For safety reasons, we strongly recommend that you remove the propeller during configuration, ensure that wiring and electrical power are present, and stay away from crowds, fragile and dangerous objects during flight. If any of the reasons below (not limited to below) occur while using our products, JIYI will not be liable for any direct or indirect loss, damage and injury arising from the use of our products. JIYI is only responsible for damage to the flight controller caused by the controller itself.
7. Flying in conditions of strong interference, radio interference and prohibited area or vision, unclear or blocked or inability to judge and recognize the state of the flight;. 9. Abnormal working condition of the flight controller caused by the user tearing or modifying the JIYI product and accessories.

If there are excessive peripherals mounted on flight controller, it will lead to insufficient power supply and connection failure, and at this moment it needs power supply.
Connect to the FCU
The configuration FCU
If the throttle is placed in 50% position, the aircraft will be in alt-hold flight. If the aircraft is in motion, all the control sticks of remote controller return to the middle position, the aircraft will brake and hover automatically. CH3 Controls speed from altitude When the throttle is in the middle, the aircraft remains at a constant altitude. Unlike the GPS angle mode, the stick could no longer control the roll angle of the aircraft, but strictly controls the flight speed of the aircraft in roll direction.
Different from GPS angle mode, the stick could no longer control the pitch angle of the aircraft, but strictly controls the airspeed of the aircraft in pitch. Make the plane fly to the desired location and hover the plane. Change the joystick on AB record to Gear 3. The FCU will record the current position as the return-to-home waypoint whenever users clock off the aircraft.
When CH6 switches to the one-key return-home position or the FCU is in the FS protection status, the aircraft will automatically rise to a set altitude if the distance between the aircraft and the return waypoint exceeds 2 meters ( if the current altitude is higher than the set return-to-home altitude, then the current altitude is used for return-to-home). During the return home, the aircraft is not manually disturbed by the control stick channel. If the distance between the aircraft and the return-to-homeway point is less than 2 meters, the aircraft will land and lock automatically.
The premise of automatic homing is that the aircraft's homing waypoint is registered. When the aircraft is near people, we suggested not to go into automatic return-to-home mode in case of an accident. 2, Placement: Placement of the down-facing radar on the underside of the aircraft.
2、Operation: the maximum flight speed can be limited to 5m/s, 8m/s or 10m/s by switching the control stick when the aircraft is flying in GPS speed mode. When the aircraft is disengaged, push the left stick of the remote as ↙ and make the RH circle counter clockwise (US style remote), then the engine sequence test will be triggered. After the aircraft is armed, the aircraft's propeller will rotate low and steady at idle (the effect will be shut down if there is no action within 3 seconds).

Flight mode introduction
Due to the flight controller's advanced algorithm, you can easily hover aircraft without operating the throttle, indoors or in a windless environment. After searching for satellite or RTK positioning, switch CH5 of the remote control to ATT-ALT mode. GPS speed mode is the strictest flight mode to control the flying speed of aircraft. It can meet the requirements of speed-sensitive users.
AB operation can be terminated in the following ways: move the CH5 bar to another flight mode, switch the AB operation control stick to Gear 1, or switch to homing. Support of banner and speed configurations in AB operation by Assistant2 Software and APP. After the aircraft arrives at the homing point, it will first hover for about 3 seconds, and then slowly descend, at this time you can check the flight status of the aircraft (but there is no response to the throttle ) from ch1 ch2 ch4 channels, which make the aircraft search for a more suitable landing site.
Its function is to control the flow of the pump. It supports two kinds of control modes: one is manual control mode which means the output of the pump is directly controlled by the remote controller. 1、Connection: connect the ESC signal wire of the water pump to the PUMP port on the FCU. 2、Switch the return-to-home channel to the highest position, press the control stick of the remote control as ↘↗ (American style remote control) or ↗↘ (Japanese style remote control), and when there is an alternating flashing of red, green and yellow light, accelerometer calibration starts.
Turn the nose down, rotate the aircraft around the axis in the direction of gravity, until the red, green and yellow LED lights alternately flash, indicating that the calibration is complete.

Introduction to the Functions of Remote Controller
Note: Do not pull the stick as shown in the above figure during flight, otherwise the motor will stop rotating immediately. And then successively press the LH stick as ↖, the RH stick as ↙, the LH stick as ↙, the RH stick as. Repeat the 4 stick push actions in the 2nd step in order, the motor sequence test will be activated.
Caution: Under normal conditions, the motor sequence test may be activated after a push action of the stick. But if the sticks are pushed to the wrong positions, the motor sequence test can only be activated after repeating the 4 stick push actions in step. You can judge whether the propeller rotations are in the opposite direction or not from the remote control.
For example, when you push the front control stick below the stall speed, the rear propeller of the aircraft should start turning while the front propeller of the aircraft should stop turning. Likewise, when you push the left control stick below idle, the left propeller of the aircraft should stop spinning while the right propeller of the aircraft should start spinning. First you are required to set the FS protection of the remote control correctly according to the user manual of the remote control.
Setting in assiatant2 software (path: Base –RC).When the GPS satellite signal is good, no matter what kind of aircraft it is, the FCU will automatically execute homing if the receiver signal is lost. If the remote control signal is recovered on the return home, switch the flight mode control channel back and forth to get the correct control if you want to control the aircraft again. GPS mode (angle, speed) Green indicator blinks twice Low function mode (surrounding, . patrol and farming etc).
Level 1 alarm yellow indicator flashes three times Low Level 2 alarm yellow indicator flashes quickly High
