Remote Control Function Guide

1.Unlocking and Locking

• Unlock

Follow the diagram to unlock. After unlocking, the motor enters idle mode.

• Locking Mechanism

a. Immediate Locking

In any flight mode, after the motor starts, performing the stick operation shown in the diagram will immediately stop the motor.

Note: In case of an emergency during flight, execute the stick operation shown in the diagram to prevent accidents.

b. Auto-Lock

All flight modes feature automatic landing detection, automatically controlling motor shutdown. When the throttle is pulled to the minimum position during flight, it will not cause the motors to stop.

2. Accelerometer Calibration

The flight controller supports accelerometer calibration via the app or parameter adjustment software. Follow these steps: Place the aircraft horizontally, then tap “Accelerometer Calibration.” Calibration will complete within 3-5 seconds. Note: Do not shake the aircraft during calibration.

3.Magnetic Compass Calibration

The K++ flight controller supports magnetic compass calibration via remote control stick movements. Proceed as follows:

With the flight controller locked, rapidly toggle the 5th channel flight mode switch back and forth to enter dual-plane magnetic compass calibration. A steady yellow LED indicates horizontal calibration. Position the aircraft level with gravity aligned along the axis. Rotate clockwise until the LED turns solid green, then proceed to vertical calibration. With the nose pointing down and gravity aligned along the axis, rotate until the LED alternates between red, green, and yellow flashes, indicating calibration completion.

4. Motor Testing

The motor testing function includes sequential motor testing and rotation direction testing. It primarily verifies the correct installation sequence and rotation direction of motors to prevent accidents caused by incorrect installation.

• Motor Sequence Test

With the system locked, move the left stick ↙ and perform a counterclockwise circular motion with the right stick ↗↖↙↘ (American-style control). This initiates the motor sequence test, causing motors 1 through 8 to idle-start sequentially.

Japanese-style joystick sequence test procedure: 1. Move left stick ↙ and right stick ↘ and hold; 2. Then move left stick ↖, right stick ↙, left stick ↙, right stick ↘. Throughout this sequence, keep the left stick fully left and the right stick fully down. Repeat the four joystick movements from step 2 to trigger the generator sequence test.

Note:

Under normal conditions, executing one stick movement triggers the generator sequence test. If stick positioning is inaccurate, repeat all four movements in step 2 to trigger the test.

• Motor Direction Test

After unlocking, the aircraft’s propellers should run smoothly at low idle speed. Use the transmitter’s four channels to verify whether forward/reverse and left/right steering produce opposite effects. For example: – At idle, pushing the forward stick causes the rear propellers to rotate while the front propellers stop. – Similarly, moving the left stick causes the left propellers to stop while the right propellers rotate.

5.Remote Control Loss Protection

First, correctly configure remote control loss protection in the Parameters Adjustment Software under the Basic -> Remote Control interface. When GPS satellite signals are strong, if the receiver signal is lost, the flight controller will execute loss protection regardless of the aircraft’s current flight mode. If the remote control signal is restored and you wish to regain control of the aircraft, you must toggle the flight mode channel to reacquire control.

Introduction to Flight Mode

1.Attitude Mode

Attitude Mode is suitable for users returning to the control center. During flight, the IMU, GPS, magnetic compass, and barometer all participate in operation. Attitude Mode can automatically switch control methods based on GPS signals. When GPS is unavailable or weak, it uses altitude hold flight; when GPS signals are strong, it enables precise positioning and altitude hold. Attitude Mode does not feature terrain following.

• Working Conditions

The Attitude Mode requires the GPS module to be operational, necessitating completion of satellite acquisition and attainment of the required positioning accuracy. As shown below, when the LED indicates a GPS status of “GPS Signal Normal”, “GPS Signal Excellent”, or “RTK Positioning”, the device can be unlocked or switched to this mode.

The flight controller can only be unlocked in Attitude Mode; it cannot be unlocked in other modes. After entering Attitude Mode, the green LED will flash once.

• Operation Instructions

After GPS satellite acquisition completes and positioning succeeds, switch the remote control’s 5-channel mode selector to Attitude Mode. After unlocking the stick, motors idle below 50% throttle. Gently push throttle beyond 50% for takeoff. When the throttle stick is released to the 50% position, the aircraft will hover at altitude. When the aircraft is in motion, returning all control sticks to center position will automatically engage brakes and initiate hovering.

Specific stick functions are detailed in the table below:

2. Manual Operation Mode

Manual Operation Mode, also known as GPS Mode, utilizes the IMU, GPS, magnetic compass, and barometer during flight. This mode features terrain-following capability.

• Operating Conditions

Operating conditions are identical to Attitude Mode. This mode cannot be unlocked directly. First unlock in Attitude Mode before switching to this mode. Upon entering Manual Operation Mode, the LED green light will flash twice.

• Operation Instructions

After unlocking in Attitude Mode, switch the 5-channel mode selector on the remote controller to the Manual Operation Mode position. When the throttle stick is set to 50%, the aircraft will hover at a fixed altitude and position. If the aircraft is in motion, returning all remote controller sticks to center position will cause the aircraft to automatically brake and hover.

3. Route Operation Mode

Route operation mode enables autonomous flight planning via the mobile app, where users map fields and adjust flight paths before the flight controller executes tasks independently.

• Operating Conditions

After satellite acquisition completes and positioning accuracy meets requirements (LED red light stops flashing or flashes once), click “Execute Task” in the app’s operation interface. Once parameters are set, the flight controller automatically unlocks and takes off. Upon entering route operation mode, the LED green light flashes four times.

4. Auto Return Mode

Auto Return Mode provides safety assurance for long-distance flights and loss-of-control protection.

• Operating Conditions

After satellite acquisition completes and positioning accuracy meets requirements (LED red light stops flashing or flashes once), the flight controller automatically records the current position as the return point each time the user unlocks. Upon entering Auto Return Mode, the LED green light flashes rapidly.

• Operation Instructions

Auto Return mode can be triggered via the joystick or through loss-of-control protection. When the CH6 mode switch on the remote control is set to the one-touch return position, or when the flight controller enters loss-of-control protection, if the aircraft is more than 2 meters away from the return point, it will automatically ascend to the preset altitude (if the current altitude exceeds the set return altitude, it will return at the current altitude). Upon reaching the return point, the aircraft will first hover for approximately 3 seconds before slowly descending. During this phase, the flight state can be controlled via the remote control sticks (though the throttle stick will not function), allowing the aircraft to seek a more suitable landing spot. The aircraft will automatically lock once it has fully landed. If the aircraft is within 2 meters of the return point, it will land in place and automatically lock.

Important Notes:

Automatic return requires the return point to be pre-recorded. To use this feature, ensure GPS satellite acquisition is complete before unlocking. Refer to the appendix for LED indicator meanings.

When the aircraft is near people, avoid activating automatic return to prevent accidents.
