TECHING 1/12 Scale Dual Spool Turbofan Engine Model Kit | Build Your Own Metal Jet Engine
Hero Section: Hold the Heart of Aviation in Your Hands
For over a century, the jet engine has been the pinnacle of human engineering—a complex beast of fire and air that conquered the skies. But few have ever seen the inner workings of this mechanical marvel. The TECHING DM121 changes that. This isn't just a model; it is a 1/12 scale tribute to the "Heart of Flight." Whether you are a seasoned pilot, an aspiring aerospace engineer, or a collector of fine mechanical art, this kit invites you to strip away the cowling and build a functioning, motorized turbofan engine from scratch.
Why Choose the TECHING DM121 Turbofan Kit?
- A Masterpiece of Metal: Forget flimsy plastic snap-together kits. This model is constructed from high-strength aluminum and zinc alloys. With a weight of 2.8kg, it possesses the cold, heavy, industrial feel of a real machine. The metallic finish is not just paint; it’s the result of precision casting and anodizing.
- True "Dual Spool" Mechanics: Authenticity is key. This model faithfully replicates the dual-spool structure of modern high-bypass turbofans. You will assemble the high-pressure and low-pressure rotors independently, understanding exactly how they interact to generate thrust.
- Cutaway for Clarity: The casing features a strategic cutaway design. Once assembled, you don't hide your work. You can see the fan blades spinning, the compressor stages compressing, and the turbine rotating, offering a perfect visual lesson in thermodynamics and aerodynamics.
- Motorized & Alive: This is kinetic art. Equipped with a built-in electric motor and a rechargeable 800mAh lithium battery, the engine roars to life at the push of a button. It doesn't just sit there; it simulates the operation of a real jet turbine.
Technical Highlights: Engineering Decoded
- 300+ Precision Components: Every screw, blade, and casing part is engineered for a precise fit. The assembly process is a journey through aerospace logic, requiring patience and focus.
- Electric Drive System: The model integrates a hidden motor drive system powered by a 3.7V lithium battery. It supports USB charging, giving you 30 minutes of continuous run time to show off your creation.
- Educational Value: This is the ultimate STEM tool for adults and students (16+). It physically demonstrates concepts like bypass ratio, compression stages, and the role of the N1 and N2 shafts in a way that textbooks simply cannot.

Usage Scenario: The Ultimate Desk Statement
Imagine this on your executive desk or in your workshop. It’s a conversation starter like no other. When a friend or colleague asks about it, you don't just explain it—you turn it on. The blades spin up, the turbine rotates, and you share the story of how you built it piece by piece. It is a bridge between the dream of flight and the reality of engineering.
Important Tips from the Hangar
- Wire Management: During assembly, pay close attention to the routing of the motor wires. Ensure they are tucked away neatly within the designated channels to prevent them from rubbing against the spinning rotors.
- Lubrication: While the parts are precision-made, a tiny drop of light machine oil (not included) on the main shaft bearings can ensure smoother operation and reduce noise.
- Patience is a Virtue: With 300+ parts, take your time. Organize your screws and components before starting. The 2-hour build time is an estimate; enjoy the process rather than rushing to the finish line.
