Batteries Charging Method

The Lipo battery can be charged using the provided USB charger via several methods:

1. Charging via Computer USB Port:

   1. Connect the USB charger to a computer's USB port.

   2. Connect the Lipo battery to the USB charger. The blue indicator light will flash during charging, and all four lights will be solid when fully charged. (⚡ flashing blue ladder, ✔️ four lights on)

2. Charging via Power Supply Adapter:

   1. Connect the USB charger to a compatible power supply adapter.

   2. Connect the Lipo battery to the USB charger. The blue indicator light will flash during charging, and all four lights will be solid when fully charged. (⚡ flashing blue ladder, ✔️ four lights on)

3. Charging via Power Bank:

   1. Connect the USB charger to a power bank.

   2. Connect the Lipo battery to the USB charger. The blue indicator light will flash during charging, and all four lights will be solid when fully charged. (⚡ flashing blue ladder, ✔️ four lights on)

First Flight Preparation

CAUTION:

• Ensure sufficient power supply for both the transmitter and the helicopter.
• Fly in a suitable, open space away from traffic, people, electricity pylons, and pools.
• Do not lock the main rotor screws too tightly to allow for smooth folding. If the main rotor screws are too tight, the helicopter may shake during flight.
• In an emergency situation, you can press the "sharp stop" button (?) for 3 seconds to land the helicopter without rotation. (Note: This action may cause the helicopter to crash.)

Installation Method of Remote Controller Battery

To install batteries in the transmitter:

1. Locate the battery lid on the transmitter.
2. Push and slide the battery lid open following the indicated direction [arrow].
3. Insert 4 AA-sized batteries, ensuring they are installed according to the polarity indicated inside the compartment.
4. Do not mix batteries of different chemistries or specifications.

Direction of Operation

Familiarize yourself with the controls before your first flight:

• Throttle: Controls the vertical movement.
  • Throttle up: Climb [climb]
  • Throttle down: Descend [descend]
• Rudder: Controls the helicopter's yaw (rotation around its vertical axis).
  • Rudder left: Nose yaws left [yaw left]
  • Rudder right: Nose yaws right [yaw right]
• Elevator: Controls the helicopter's pitch (forward/backward movement).
  • Elevator up: Moves forward [forward]
  • Elevator down: Moves backward [backward]
• Aileron: Controls the helicopter's roll (sideways movement).
  • Aileron left: Moves left [left]
  • Aileron right: Moves right [right]

Note: Beginners should pay attention to the direction of flight. Keep the head forward to avoid causing injury.

Flight Operation Steps

1. Turn on the transmitter and place the helicopter near it.
2. Install the aircraft battery securely in the battery compartment. Press the power switch for 2 seconds to turn on the aircraft power. (?)
3. The lights on the helicopter and the remote control will flash simultaneously. Push the throttle stick from top to bottom quickly. The remote control will make a 'DI' sound, and the indicator lights on the helicopter and remote control will remain solid, indicating successful binding. (?)
4. Pull both control sticks to the outer eight angles simultaneously to start the helicopter rotors. Alternatively, press the one-key takeoff button (⬆️) to take off directly.
5. Keep the helicopter head forward and maintain a safe distance from it.
6. When manually landing the aircraft, keep the throttle stick at the bottom for 2-3 seconds, then release it after the propeller has completely stopped rotating. (This step is not required when using the one-key landing function.)

Notes:

1. To avoid collisions, do not look at the helicopter at hip level when it flies.
2. To avoid distractions, confirm that no other transmitters are operating nearby.

Flight Yaw Correction Method

The helicopter has a set hovering function. If you are dissatisfied with hovering or if the helicopter has a yaw (unwanted rotation), follow these steps to adjust:

1. Take off using the throttle joystick.
2. According to the direction of the yaw, press the fine-tuning button (⚙️) in the opposite direction until the helicopter hovers stably.

Yaw Correction Examples:

• Forward/backward Yaw: Fine-tune according to the direction of the arrow [arrow].
• Left/right Yaw: Fine-tune according to the direction of the arrow [arrow].
• Side fly Yaw: Fine-tune according to the direction of the arrow [arrow].

Note: Maintain a flying altitude above one meter (? 1m+).

Introduction of Receiver Sockets

The receiver board has various connection points for different components:

• Tail motor
• Main motor
• LED
• Aileron steering gear left
• Aileron steering gear right
• Before and after steering gear (likely refers to elevator servo)
• Optical flow localization sensor
• Gyroscope

Parts Replacement Instructions

• Propeller Replacement: Use the hexagon wrench to remove the propeller. Ensure smooth propeller rotation. Pay attention to matching propeller A with slot A, and B with B, to ensure balance. The installation of new propellers should not be too tight.
• Tail Rod Replacement: First, disassemble the housing. Then, remove the tail motor plug. Pull the tail rod backwards, paying attention to the direction of installation. After installing the tail rod, fix the machine shell screws. When fixing the screws, ensure the direction of the tail skid is vertical and not deflected.
• Steering Gear (Servo) Replacement: When changing a steering gear, pay attention to the direction of the connecting rod. When changing other internal parts, pay attention to the installation order and position.
• Tail Rotor Replacement: When removing and replacing the tail rotor, pay attention to its direction. Align the motor shaft and press it slowly to ensure smooth rotation.

Gyro Calibration Method

1. If experiencing yaw issues during flight, land the helicopter and calibrate the gyroscope.
2. During calibration, the aircraft must be placed on a level ground (?).
3. The indicator light will flash quickly during the calibration process. Take off when the indicator light stops flashing.
