How do you make my nitro RC boat fatser?

To make your nitro RC boat faster, start by optimizing the engine tuning for better performance: adjust the carburetor for the correct air-fuel mixture and ensure the engine is running at the right temperature. Additionally, consider upgrading to a higher-performance propeller that matches your boat's setup, as a better pitch can improve speed. Reducing weight by removing unnecessary components or using lighter materials can also enhance speed and acceleration. Lastly, ensuring that the hull is clean and free of debris will minimize drag and improve overall performance.
