Realistic 1/10 Dual Rotor Turbofan Engine Model A detailed, motordriven scale model that reproduces the structure and working principles of a fullsized turbofan engine. Designed for hobbyists, educators, and technical demonstrations, this aluminum alloy and stainless steel assembly provides a handson look at key engine components while delivering dynamic, visible operation. Key benefits Realistic simulation: Replicates main engine components including a firststage fan, twostage lowpressure compressor, fourstage pressure compressor, firststage pressure turbine, and twostage lowpressure turbine for accurate visual and educational reference. Handson learning: Full assembly experience of 1000+ parts teaches mechanical assembly skills, component relationships, and turbofan operation principles. Dynamic demonstration: Hollowed engine case and motordriven system let you see moving parts in operation. Included throttle lever and engine sound module make demonstrations more informative and engaging. Durable materials and precise construction: Main structure uses aluminum alloy and stainless steel for realistic weight and feel. Portable power and easy charging: Runs on a 3.7V 800mAh lithium battery, charges via DC 5V USB cable, 3 hours charging time, approximately 1 hour run time at full charge. Specifications Model: Dual Rotor Turbofan Engine, scale 1/10 Model length: 380 mm Fan diameter: 165 mm Number of parts: 1000+ PCS (components 400+ PCS, screws and nuts 600+ PCS) Drive system: Motordriven Battery: 3.7V 800mAh lithium battery Charging cable: DC 5V USB cable Charging time: 3 hours Battery life: 1 hour at full charge Assembly time: Approx. 10 hours Difficulty level: 5 of 5 Product weight: 5220 g Package weight: 7780 g Product dimensions (assembled): 38 x 16.5 x 23.5 cm Package dimensions: 38 x 18 x 25 cm Material: Aluminum alloy and stainless steel Recommended age: 14 and up What is included Engine kit x1 Tools set x1 Instructions (paper, English) x1 How this model stands out Accurate internal layout and component count provide a nearrealistic representation suitable for technical study and display. Visible, motorized operation with mounting bracket allows secure demonstrations and close observation of rotating stages. Complete hardware kit including screws and nuts mirrors real assembly work and enhances mechanical understanding. Suggested use scenarios STEM classroom or workshop: Use as a teaching aid to explain turbofan components, airflow stages, and rotating machinery behavior during lab sessions or demonstrations. Hobbyist project and display: A challenging build for model enthusiasts who want a detailed, durable display piece with working motion and sound. Technical demonstration or exhibition: Place on a fixed stand for museum displays, trade show exhibits, or engineering presentations to illustrate turbomachinery principles. Notes for builders Expect a detailed build that takes about 10 hours and requires patience and careful following of the included instructions. Recommended for users aged 14 and up due to small parts and assembly complexity. Keep the included USB charging cable available for convenient recharging between demonstrations. This model provides a faithful, functioning turbofan engine replica for education, display, and advanced hobby assembly without altering the original engineering layout or core specifications.
