TECHING DM119 1/10 Scale Metal DIY Dual Spool Turbofan Engine Model Kit with Sound
Hero Section: Build the Crown Jewel of Modern Industry
The turbofan engine is often called "the jewel in the crown of industrial manufacturing"—a pinnacle of human engineering that combines extreme precision with raw power. The TECHING DM119 allows you to conquer this mechanical summit. This is not a simple toy; it is a museum-grade, 1/10 scale kinetic sculpture comprising over 1,000 parts. Designed for the serious enthusiast, this kit invites you to spend 10+ hours immersed in the world of aerospace engineering, building a fully functional, motorized, and sound-equipped replica of a commercial aircraft engine.
Why Choose the TECHING DM119 Turbofan?
- Unrivaled Scale & Detail: At 38cm long and weighing 4kg, this model commands presence. It faithfully reproduces the internal structure of a real jet engine, including a first-stage fan, two-stage low-pressure compressor, four-stage high-pressure compressor, and multi-stage turbines.
- Premium Metal Construction: Crafted from anodized aluminum alloy and stainless steel using CNC precision casting, the DM119 rejects plastic. The cool touch of metal and the industrial grey finish give it the look and feel of a genuine aviation component.
- Alive with Sound and Motion: This model engages all senses. It features a dedicated throttle lever that controls the speed of the motor. As you push the throttle, the built-in sound module roars to life, simulating the spool-up sound of a real jet turbine, synchronized with the rotation of the blades.
- The Ultimate STEM Challenge: With over 1,000 pieces (including screws), this is a project that demands patience and focus. It is the ultimate "digital detox," allowing you to disconnect from screens and reconnect with the satisfaction of mechanical assembly.
Technical Highlights: Aviation Engineering Decoded
- True Dual-Spool Architecture: Just like a real engine, the DM119 features independent high-pressure and low-pressure rotors (Dual Spool). This allows you to visualize how the N1 and N2 shafts operate at different speeds to maximize efficiency.
- Cutaway Casing: The hollowed-out engine case provides a window into the machine's soul. You can observe the airflow path, seeing how the compressor stages squeeze the air before it reaches the combustion chamber and turbine.
- Precision Drive System: Powered by a 3.7V lithium battery, the internal motor drives the massive fan assembly smoothly. The system is designed to run for up to an hour on a full charge, making it perfect for long demonstrations.

Usage Scenario: The Executive Statement Piece
Once assembled, the DM119 becomes the centerpiece of any room. Imagine it on an executive desk, a bookshelf in a study, or a workbench in a garage. When guests arrive, you don't just show it to them; you grab the throttle lever. As the engine whines up to speed and the sound module kicks in, you aren't just displaying a model—you are sharing a passion for the marvels of flight.
Important Tips from the Hangar
- Workspace Preparation: This is a massive build. Clear a large table and use magnetic trays to sort the hundreds of screws. Do not open all bags at once; follow the manual step-by-step.
- Lubrication: With so many moving metal parts, friction is the enemy. Apply a small amount of light machine oil or grease (not included) to the shaft bearings and gears during assembly to ensure smooth, quiet operation.
- Wiring Care: When installing the sound module and motor, be extremely careful with the wire routing. Ensure wires are secured away from the spinning rotors to prevent damage.
