Setup
1. Charging the LiPo Battery
- Connect the USB-C smart charger to a compatible USB power source (e.g., computer, wall adapter).
- Connect the 2S 7.4V 600mAh LiPo battery to the charger. Ensure correct polarity.
- Allow the battery to charge fully. The charger's indicator light will change to show charging status (refer to charger instructions for specific light patterns).
- Important: Always supervise LiPo battery charging. Do not charge unattended.
2. Installing Transmitter Batteries
- Open the battery compartment on the back of the 2.4GHz transmitter.
- Insert the four (4) AA batteries, ensuring correct polarity (+/-).
- Close the battery compartment securely.
3. Preparing the Boat
- Carefully remove the boat's canopy to access the internal electronics.
- Connect the fully charged LiPo battery to the Electronic Speed Controller (ESC) connector inside the hull.
- Ensure all wires are neatly tucked away to prevent interference with moving parts or damage when replacing the canopy.
- Securely reattach the canopy, ensuring a watertight seal.
4. Steering Endpoint Adjustment (Recommended)
To optimize steering performance and prevent potential servo damage, it is recommended to adjust the steering endpoints. Refer to your transmitter's manual for specific instructions on how to set steering travel limits. This prevents the servo from over-traveling and stalling, which can lead to premature wear.
Operating Your Sprintjet
1. Pre-Run Checklist
- Ensure the LiPo battery is fully charged and securely connected inside the boat.
- Verify the transmitter batteries are fresh or fully charged.
- Check that the boat's canopy is properly sealed.
- Inspect the jet pump for any obstructions.
2. Powering On
- Turn on the transmitter first.
- Then, turn on the boat's power switch (located inside the hull, accessible by removing the canopy if not externally mounted).
- Wait for the boat and transmitter to establish a connection (indicated by LED lights, refer to specific component manuals).
3. Launching and Controls
Gently place the boat in the water. Use the trigger on the transmitter for throttle control (pull for forward, push for reverse/brake). Use the steering wheel for directional control (left for left, right for right). The jet pump design provides excellent maneuverability.

4. Self-Righting Feature
The Sprintjet features a self-righting hull design. If the boat flips over during operation, apply full throttle briefly. The boat should automatically right itself. If it does not, try reversing and then applying full throttle again. This feature is most effective in calm water conditions.
5. Operating Environment
Operate the Sprintjet in calm, open water free of debris, weeds, and other obstacles. Avoid operating in strong currents or high winds. Always maintain a clear line of sight to your boat.

Maintenance
1. After Each Run
- Dry the Boat: Thoroughly dry the exterior of the boat with a soft cloth.
- Internal Drying: Remove the canopy and disconnect the battery. Use compressed air to blow out any moisture from the internal electronics compartment. This is crucial for preventing corrosion.
- Inspect Jet Pump: Check the jet pump intake and nozzle for any debris (weeds, small stones) and remove them carefully.
- Battery Care: Disconnect the LiPo battery and store it in a cool, dry place at storage voltage if not using for an extended period. Never store a fully charged or fully discharged LiPo battery.
2. Regular Inspection
- Hull Integrity: Periodically inspect the hull for cracks or damage. Repair any damage promptly to maintain watertightness.
- Motor Temperature: The 390-size brushed motor can get warm during operation. While normal, excessive heat can indicate issues. Ensure proper ventilation and avoid continuous full-throttle runs without breaks.
- Steering Linkage: Check the steering servo and linkage for smooth operation and any signs of wear or looseness.
3. Storage
Store the boat in a dry, cool environment away from direct sunlight and extreme temperatures. Ensure the battery is disconnected and stored safely.
