Realistic Racing Engine Model that combines detailed mechanics and functional motion for display and handson learning. Build a working engine with moving pistons, turbochargers, a rotating crankshaft, and cooling fans to explore core mechanical principles in a tangible way. Key benefits Understand how engines work: Visible moving parts demonstrate piston travel, crankshaft rotation, turbocharger motion, and cooling fan operation. Handson learning and skill building: The build process develops mechanical reasoning, patience, and assembly skills useful for hobbyists and students. Displayready and durable: The completed model is a compact, detailed desktop showcase that also operates in real time. Main features Functional components: Moving pistons, turbochargers, crankshaft, and cooling fans simulate real engine behavior. Power setup: Powered by an M motor and battery box (6 AAA batteries not included) for readytorun operation. Guided assembly: Includes a visual stepbystep manual to simplify construction and demonstrate how each mechanism works. quality parts: Over 980 pieces made from durable ABS plastic for a secure fit and reliable construction. Finished size: Approximately 7.28 in L x 13.35 in W x 6.14 in H when assembled. Practical uses Educational demo: Use in classrooms or workshops to explain internal combustion engine concepts and basic mechanical systems. Desk display with motion: Place on a desk or shelf as a conversation piece that operates and demonstrates movement. Hobbyist project: Ideal for model builders and car enthusiasts looking for a detailed, handson assembly experience. What you get A precisiondesigned, buildable racing engine model with simulated mechanical operations. A visual stepbystep manual for clear guidance through assembly and operation. A durable model suitable for repeated handling and demonstration. Notes Requires an M motor and battery box for powered operation; 6 AAA batteries are not included. Contains over 980 ABS parts and requires time and attention to assemble. This model provides a realistic, functional representation of a racing engine for learning, display, and handson exploration of mechanical systems.
