2. One-Touch Takeoff: Press the 'Take Off' button on the remote control for automatic takeoff. The drone will ascend to a stable hovering height.
3. Optical Flow Hovering: The drone utilizes an optical flow hovering system for stable flight, especially indoors or in areas with clear ground patterns.
4. Throttle Lever: Use the left joystick (throttle lever) to control altitude.
5. Direction Bar: Use the right joystick (direction bar) to control forward, backward, left, and right movement.
6. One-Click Landing: Press the 'One-key landing' button for automatic landing.

4.2 Camera Operation

The K21 MAX Drone features a 4K HD camera with 90° electric adjustment for multi-angle shooting.

1. Taking Photos: Press the 'Take a photo' button on the remote control to capture still images.

4. Dual Camera Switching: The drone supports dual camera switching for varied aerial photography perspectives.

4.3 Advanced Flight Features

• Headless Mode: Activate Headless Mode (button on remote) to simplify flight control, as the drone's orientation relative to the pilot is maintained regardless of its actual front.
• 360° Flip Function: Perform stunt rolls by pressing the 'One-touch 360° roll' button on the remote control.
• Speed Switching: Adjust the drone's speed using the 'Speed switching' control for different flight conditions.
• Intelligent Obstacle Avoidance: The drone is equipped with an intelligent obstacle avoidance system. When activated, it helps prevent collisions in areas with many obstacles.
• Track Flight (Waypoint Definition): Draw a trajectory on the companion app (if using phone connection) to enable the drone to fly autonomously along the defined path.

5. Maintenance

Proper maintenance ensures the longevity and optimal performance of your K21 MAX Drone.

• Cleaning: Regularly clean the drone body, propellers, and camera lens with a soft, dry cloth. Avoid using harsh chemicals.
• Propeller Inspection: Before each flight, inspect propellers for any cracks, bends, or damage. Replace damaged propellers immediately using the spare blades provided.
• Battery Care: Store batteries in a cool, dry place. Do not overcharge or over-discharge batteries. If not used for extended periods, charge them to about 50% capacity.
• Storage: When not in use, store the drone and its accessories in the provided storage bag to protect them from dust and physical damage.

6. Troubleshooting

If you encounter issues with your K21 MAX Drone, refer to the following common problems and solutions:

• Drone Not Responding:
  - Ensure both drone and remote control are powered on and fully charged.
  - Re-pair the drone and remote control according to the pairing instructions (refer to the full manual if needed).
  - Check for any obstructions to the propellers.
• Short Flight Time:
  - Ensure the battery is fully charged before flight.
  - Battery performance can degrade over time; consider replacing old batteries.
  - Flying in strong winds or performing aggressive maneuvers consumes more power.
• Poor Image/Video Quality:
  - Clean the camera lens.
  - Ensure the memory card is properly inserted and has sufficient space.
  - Avoid flying in low light conditions or areas with strong electromagnetic interference.
• Unstable Flight/Drifting:
  - Perform a gyroscope calibration (refer to the full manual for specific steps).
  - Ensure propellers are correctly installed and undamaged.
  - Avoid flying in strong winds.
• Obstacle Avoidance Not Working:
  - Ensure the obstacle avoidance sensors are clean and unobstructed.
  - The system may have limitations in certain lighting conditions or with very thin objects.
