Product Details
- Build your own working miniature internal combustion engine with the SEMTO ENGINE ST-NF2 7.0cc Mini Inline Double-Cylinder Four-Stroke Air-Cooled Nitro Internal Combustion Engine Model Kit. This precision-engineered DIY kit lets you assemble a fully functional nitro engine from the ground up—a rewarding hands-on project for mechanical enthusiasts, hobbyists, collectors, and engineering students. How It Works The ST-NF2 is a 7.0cc inline double-cylinder, four-stroke, air-cooled nitro engine. When fueled with 20-25% nitro fuel and ignited by an external ignition module (sold separately), the engine produces 0.6 ps of power and can rev from 4,000 all the way up to 16,000 rpm. The asynchronous crankshaft delivers smooth power output, while the transparent operation allows you to observe the mechanical principles in real time. Precision All-Metal Construction Every component in this kit is crafted from high-quality metal using advanced CNC machining and oxidation coloring technology. The engine features a highly simulated realistic appearance with red sport accents that symbolize thunderbolt movement, making it visually closer to a real engine. The delicate surface, compact structure, and lightweight body at just 1.18 lbs make it both functional and visually stunning for desktop display. Key Engineering Features Dual Synchronous Belt Timing: The timing structure of a dual synchronous belt pulley greatly reduces the risk of gear jumping during high-speed operation, ensuring stable valve timing even at maximum RPM. Short Rocker Arm: Enables more accurate valve switch operation, improving engine efficiency and throttle response. Brand-New Signal Carburetor: Allows easier adjustment and more sensitive throttle response—less time tuning, more time enjoying. High-Torque 480 DC Motor: Provides convenient and smooth electric starting—no manual pull-start required. Asynchronous Crankshaft: Delivers strong power output and smoother operation throughout the entire RPM range. DIY Assembly Experience The ST-NF2 arrives as a kit version requiring assembly. As you build each component—pistons, cylinders, crankshafts, valves, and timing belts—you will gain a deep understanding of how a four-stroke internal combustion engine operates. This hands-on experience is ideal for mechanical engineering learning, hobbyist projects, and physics demonstrations.
