Setup & Assembly

Your V8 engine model comes as a loose pack of building blocks and requires assembly. Please follow the included paper instructions carefully for step-by-step guidance. The assembly process is designed to be educational and engaging.

Key Mechanical Features to Observe During Assembly:

• Simulated Mechanical Chain Transmission: Pay attention to the intricate chain system that mimics a real engine's timing chain.
• Transparent Cylinder Head Design: The transparent elements allow you to observe the internal mechanics, including piston movement.
• Throttle Linkage Function: The model includes a functional throttle linkage where the valve can move up and down.
• Precise Piston Motion: Observe how the pistons move precisely within the cylinders as the engine operates.
• LED Strip/Red Light Guide Tube: Integrate the LED components as instructed to enhance the visual experience.
• Detailed Exhaust System: The model features a richly detailed exhaust system.
• Openable/Closable Valves: Some models feature valves that can be manually opened or closed.

Operating Instructions

Once assembled, your V8 engine model can be controlled via a dedicated mobile application. Ensure the power box is charged and correctly connected to the motor and LED components.

1. Charging the Battery:

Connect the provided USB charging cable to the power box and a suitable USB power source. The LED indicator on the power box will show charging status.

2. APP Connection:

1. Download the official control APP from your device's app store (refer to the paper instructions for QR code or app name).
2. Ensure Bluetooth is enabled on your mobile device.
3. Open the APP and follow the on-screen prompts to connect to your V8 engine model via Bluetooth.

3. Remote Control Mode:

This mode allows you to directly control the engine's speed and sound.

• Adjustable Engine Speed: Use the acceleration slider in the APP to increase engine speed. The engine sound will increase with acceleration.
• Adjustable Engine Sound: The APP provides simulated engine sounds that correspond to the speed. The engine sound decreases with deceleration.
• Speedometer: A digital speedometer in the APP displays the current engine speed.

4. Scratch Programming Mode:

This mode allows for basic programming of the engine's actions, fostering computational thinking.

• Connect Bluetooth: Ensure the model is connected via Bluetooth.
• Command Module Combination: Drag and drop command modules within the APP interface to create sequences of actions.
• Run & Save: Execute your programmed sequence and save your creations.

Maintenance

• Cleaning: Use a soft, dry cloth to gently wipe down the model. Avoid using harsh chemicals or abrasive materials.
• Storage: Store the model in a cool, dry place away from direct sunlight and extreme temperatures to prevent material degradation.
• Battery Care: Recharge the battery regularly, even if not in use, to maintain its lifespan. Do not leave the battery fully discharged for extended periods.
• Loose Connections: Periodically check all block connections to ensure they are secure, especially after extensive play or display.

Troubleshooting

• Model Not Responding to APP:
  - Ensure the power box is turned on and charged.
  - Verify Bluetooth is enabled on your device and the APP is correctly paired with the model.
  - Try restarting the APP and the model's power.
• Motor Not Running:
  - Check all connections from the power box to the motor.
  - Ensure the battery is sufficiently charged.
• LED Lights Not Working:
  - Check the connection of the LED strip/luminous component to the power box.
  - Ensure the power box is on and charged.
• Difficulty with Assembly:
  - Refer to the detailed paper instructions provided with the kit. Ensure each step is followed precisely.

User Tips

• Patience is Key: Building these models requires patience and attention to detail. Take your time and enjoy the process.
• Educational Value: Use the assembly process as an opportunity to learn about V8 engine mechanics, power transmission, and basic programming concepts.
• Creative Programming: Experiment with the Scratch programming mode to create unique engine behaviors and sequences.
• Display Your Creation: Once complete, the V8 engine model makes an impressive display piece, showcasing your building skills.
