Warning And The Guide Of Using Battery

ACAUTION: Always use a charger compatible with batteries.

WARNING: Always charge batteries away from flammable materials.

WARNING: Never leave charging batteries unattended.

WARNING: Never charge damaged batteries.

WARNING: Never alter batteries.

WARNING: Never touch or use hot batteries.

Using the original factory USB charger ensures charging safety. It is recommended to use the original factory USB charger; other chargers may cause battery damage and property damage.

Warnings! The battery may fire, explode, or leak if instructions are not strictly followed:

• Do not immerse the battery in water or seawater. Keep the battery in a cool, dry environment during standby periods.
• Keep all batteries out of the reach of children. Consult a doctor immediately if a battery is swallowed.
• Do not use or leave the battery near a heat source such as fire or heater.
• Use the battery charger specifically designed for this purpose when recharging.
• Do not reverse the positive (+) and negative (-) terminals.
• Do not connect the battery to an electrical outlet.
• Do not dispose of the battery in fire or heat.
• Do not short-circuit the battery by directly connecting the positive (+) and negative (-) terminals with metal objects such as wire.
• Do not transport or store the battery with metal objects such as necklaces or hairpins.
• Do not strike or throw the battery against hard surfaces.
• Do not directly solder the battery.
• Do not unpack the battery with a nail or other sharp object.
• Never disassemble the battery.

Note: The battery should not be left under full power or low power for extended periods, as this may prevent charging or cause damage. For long-term storage, charge the battery to 7.8V and store it in a dry, safe place.

Installation method of remote controller battery

Diagram: Shows the back of the remote control, with an arrow indicating how to slide the battery lid open. Also shows the battery compartment with four AA batteries installed according to polarity.

Instructions: Slide the battery lid to open by following the arrow. Please use 4 AA-sized batteries, installed based on the polarity indicated in the case. Do not mix batteries of different chemistry/specifications.

Battery mounting method

Diagram: Three steps illustrating the battery installation into the helicopter:

1. Open the hatch and place the battery into the battery compartment.
2. Position the battery properly.
3. Switch the battery's power button to OFF to prevent any looseness.

First Flight Preparation CAUTION

1. Ensure sufficient power supply for the transmitter and helicopter.
2. Keep flights in a suitable space away from traffic, people, electricity pylons, and pools.
3. Do not overtighten the main rotor screws to ensure smooth folding. Overtightened screws can cause the helicopter to shake during flight.
4. In an emergency, press the "sharp stop" button for 3 seconds to land the helicopter without rotation. (Note: This action may cause the helicopter to crash.)

Direction of operation

If you are unfamiliar with the controls of the C189, take time to familiarize yourself before your first flight.

Throttle

Diagram: Shows the effect of throttle control: Throttle up causes the helicopter to climb, and throttle down causes it to descend.

Rudder left

Diagram: Shows the effect of left rudder control: Nose yaws left.

Rudder right

Diagram: Shows the effect of right rudder control: Nose yaws right.

Elevator

Diagram: Shows the effect of elevator control: Elevator up moves the helicopter forward, and elevator down moves it backward.

Aileron

Diagram: Shows the effect of aileron control: Aileron left causes the helicopter to roll left, and aileron right causes it to roll right.

Flight Operation Steps

1. Turn on the transmitter and place the helicopter near it.
2. Install the aircraft battery securely in the battery compartment and turn on the aircraft power.
3. The lights on the helicopter and the remote control will flash simultaneously. Push the throttle stick quickly from top to bottom. The remote control will make a 'DI' sound, and the indicator lights on both the helicopter and remote control will remain steady, indicating successful binding.
4. Pull both joysticks to their outer eight angles to start the helicopter. Alternatively, press the one-key takeoff button for direct takeoff.
5. Keep the helicopter's head facing forward and maintain a safe distance.
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 is not required when using the one-key landing function).

Note:

1. To avoid collisions, do not look at the helicopter at hip level while it is flying.
2. To avoid distractions, ensure no other transmitters are operating nearby.

Flight Yaw correction method

Press the trimming button when the helicopter exhibits yaw problems.

The helicopter is set up for hovering. If you are dissatisfied with hovering or if the helicopter has a yaw, follow these steps to adjust:

Take off using the throttle joystick. According to the direction of yaw, press the fine-tuning button in the opposite direction until the helicopter hovers steadily.

Diagram: Illustrates the process of correcting yaw by using the fine-tuning button.

Receiver diagram

Diagram: Shows the layout of the receiver board with labeled components:

Gyro calibration method

Diagram: Shows the remote control and helicopter during the calibration process.

1. When experiencing yaw during flight, land the helicopter and calibrate the gyroscope.
2. Ensure the aircraft is placed on a level ground during gyroscope calibration.
3. The indicator light will flash quickly during calibration. The indicator light will stop flashing when calibration is complete and the helicopter is ready for takeoff.
