8. Environmental Requirements Before Flight

Fly in an outdoor open environment without rain or snow, with wind power less than 3. Stay away from people, trees, wires, tall buildings, airports, and signal transmission towers.

Note: APP can only be used for viewing (photographed/recorded) when the remote controller is not in use.

9. Pre-flight Preparation Instructions (Using Remote Control)

9.1 Turn on the aircraft: Place the aircraft on a horizontal plane. The front blue and red lamps will flash, indicating frequency matching state.

Note: Ensure the aircraft is correctly oriented with the nose facing forward on a horizontal plane.

9.2 Frequency Matching: Press and hold the power switch button on the remote control (step 1). The power indicator will turn on. Push the throttle lever up to the end (step 2 and 3). Code-matching will succeed, and the aircraft lights will change from flashing to solid.

Warning: Ensure sufficient power for the aircraft and remote control for takeoff.

9.3 Horizontal Calibration: Long press the calibration key on the remote controller. The aircraft's LED lights will flash. When the lights stop flashing, calibration is complete, and the remote controller will emit a "beep" sound.

Note: Calibration must be done on a horizontal plane.

9.4 Start/Stop: Push the left control lever upward to take off (Figure 2). All aircraft indicator lights will be solid. To stop the aircraft mid-flight, short press the designated key (Figure 3).

Note: This stop function is for uncontrolled states. For normal operation, use the one-key takeoff/landing key.

9.5 One-key Take-off and Landing: Gently press the “One Key Takeoff/Landing” key. The aircraft will rise to about 1 meter for stable flight. Pressing the key again will initiate a slow landing.

Warning: Follow the sequence: Turn on → Frequency Matching → Horizontal Alignment → Start/Stop → One-key Takeoff/Landing.

10. Remote Control Method

• Throttle Control: Push the left joystick up to increase blade rotation and ascend. Push down to decrease rotation and descend.
• Rudder Control (Left): Push the left joystick left to turn the aircraft left. Push right to turn the aircraft right.
• Rudder Control (Right): Push the right joystick up to move forward. Push down to move backward.
• Rudder Control (Right): Push the right joystick right to deviate right. Push left to deviate left.

11. 360° Roll

Perform 360° rolls using joystick operations. Ensure an altitude of about 1.5 meters for better performance. Rolling during ascent helps maintain altitude.

• 11.1 360° Roll Left: Short press the 360° roll button, then push the right joystick left.
• 11.2 360° Roll Right: Short press the 360° roll button, then push the right joystick right.
• 11.3 Roll Forward 360°: Short press the 360° tumble button, then push the right joystick upward.
• 11.4 360° Roll Backward: Short press the 360° roll button, then push the right joystick down.

12. Introduction of Remote Control Function and Operation

12.1 Headless Mode: The default front in headless mode is the aircraft's front during frequency matching. To adjust direction, restart frequency matching, enter the APP, and press the "headless mode" key. Press again to exit.

Special Prompt: Ensure the aircraft is aligned with a straight line for gyroscope detection and headless mode straight-line flight.

12.2 One Key Return: If the aircraft flies too far, use the return function. Ensure the remote control faces the aircraft's tail during code-matching. During flight, press and hold the one-key home button. The aircraft will return when a "beep" is heard. Any joystick operation will cancel the return.

12.3 Speed Switching: The aircraft defaults to low-speed mode (3-geared). Press the remote control for "beep" (low speed), "beep beep" (medium speed), or "beep beep beep" (high speed).

12.4 Fine Tuning Function:

• Forward/Backward Fine-Tuning: If the aircraft drifts backward, hold the forward fine-tuning key. If it drifts forward, hold the backward fine-tuning key.
• Left/Right Fine-Tuning: If the aircraft drifts right, hold the left fine-tuning key. If it drifts left, hold the right fine-tuning key.

12.5 Induction Mode: Press the remote control/induction switch button to enter induction mode. Keep your palm 10 cm from the aircraft. If the aircraft flies too high, it will descend automatically after 5-15 seconds.

12.6 Inductive Roll: Place both hands on the left and right inductive heads. After two seconds, the aircraft will automatically roll 360°.

12.7 Stop Flight

Turn the aircraft upside down to stop flight.

12.8 Throw Flight Mode

Turn on the aircraft and place it on a horizontal plane. If no frequency matching occurs within 3 seconds, stretch the aircraft forward. When the blue and red lamps flash slowly, throw the aircraft upward or swing downward for automatic takeoff.
