Safety Precautions
- Always operate the boat in open water, away from swimmers, wildlife, and other watercraft.
- Do not operate in saltwater, as it can damage internal components.
- Ensure all hatches are securely closed before placing the boat in water to prevent water ingress.
- Keep fingers and loose clothing away from the propeller when the boat is powered on.
- Supervise children at all times during operation.
- Do not attempt to retrieve a stalled boat by swimming. Use a retrieval device or another boat.
- Always remove the battery from the boat and transmitter when not in use.
- Charge batteries only with the provided charger and follow all charging instructions carefully.

Setup
1. Charging the Boat Battery
The boat is powered by an 11.1V 1000mAh Lithium Polymer (LiPo) battery. Use only the provided LiPo battery charger.
- Connect the LiPo battery to the charger.
- Plug the charger into a suitable power source.
- Monitor the charging process. The indicator light on the charger will change when charging is complete. Refer to the charger's specific instructions for details.
- Important: Never leave charging batteries unattended. Disconnect the battery once fully charged.
2. Installing Transmitter Batteries
The remote control transmitter requires 4x AA batteries (not included).
- Open the battery compartment on the back of the transmitter.
- Insert 4x AA batteries, ensuring correct polarity (+/-).
- Close the battery compartment securely.

3. Installing the Boat Battery
- Carefully remove the top hatch of the boat.
- Place the charged LiPo battery into the battery compartment inside the hull.
- Connect the battery connector to the boat's power connector.
- Ensure all wires are tucked away and do not interfere with the hatch closure.
- Securely close the top hatch to maintain the boat's waterproof integrity.
Operating Instructions
1. Powering On and Pairing
- Place the boat on a stable surface (not in water yet).
- Turn on the boat's power switch (located inside the hull, near the battery).
- Turn on the remote control transmitter using the On/Off switch.
- The boat and transmitter should automatically pair. A successful pairing is usually indicated by a solid light on both devices.
- Once paired, gently place the boat in the water. The propeller will only activate when the boat is in water to prevent accidental injury.
2. Basic Controls
- Throttle: Use the trigger on the transmitter to control forward and reverse speed. Pull for forward, push for reverse. The full-throttle control allows for precise speed adjustments.
- Steering: Use the steering wheel on the transmitter to turn the boat left or right.
- Steering Trim: Adjust the steering trim dial to ensure the boat travels straight when the steering wheel is centered.
- Dual Rate Function: This function adjusts the sensitivity of the steering, allowing for finer control or wider turns.

3. Special Features
- Auto Self-Righting: If the boat capsizes, apply throttle briefly. The boat is designed to automatically flip back upright.
- Reverse Function: The boat is equipped with a reverse function to help navigate out of tight spots or avoid obstacles. Push the throttle trigger forward to engage reverse.
- 2.4GHz Radio Control: This system provides a control range of over 656 feet (200 meters) and excellent interference resistance, allowing multiple boats to operate simultaneously.

4. Low Battery and Over Range Alarm
The transmitter will emit an audible alarm when the boat's battery is low or if the boat goes out of range. When this alarm sounds, immediately guide the boat back to shore to prevent it from becoming stranded.

Maintenance
1. After Each Use
- Remove the boat from the water and turn off both the boat and transmitter.
- Disconnect and remove the battery from the boat. Allow it to cool before recharging.
- Open the boat's hatch and carefully drain any accumulated water. Wipe the interior dry with a soft cloth.
- Clean the exterior of the boat with a damp cloth to remove dirt or debris.
- Inspect the propeller, rudder, and cooling system for any obstructions or damage.

2. Battery Care and Storage
- Store LiPo batteries in a cool, dry place, away from direct sunlight and heat sources.
- Do not store fully charged or fully discharged LiPo batteries for extended periods. Charge them to a storage voltage (typically around 3.8V per cell) if storing for more than a few days.
- Never puncture or damage LiPo batteries. Dispose of damaged batteries properly according to local regulations.
3. Motor Cooling System
The brushless motor is water-cooled to ensure optimal performance and longevity. Regularly check the water intake and outlet for any blockages. Ensure water flows freely through the system during operation.
