A380 TR900 Turbofan Engine Model Kit Turbojet with Adjustable Thrust A precision model kit that reproduces the look and dynamic behavior of the A380 TR900 turbofan engine while serving as a handson educational tool. Designed for hobbyists, educators, and modelers who need a realistic, durable, and easytodemonstrate engine replica. Key benefits Realistic engine dynamics: Stepless 0300 RPM speed control via a precision slider lets you demonstrate thrust changes and rotor behavior smoothly and continuously. Visual thrust simulation: Red LED afterburner effects mimic real thrust dynamics for demonstration and display. Portable, rechargeable power: Builtin rechargeable lithium battery charges via TypeC in 1.5 hours and eliminates the need for disposable batteries. Speed can be adjusted while charging for uninterrupted demos. Durable engineering for reliable operation: Metallic PLA fan blades reinforced for strength and stainless steel bearings ensure ultrasmooth rotation at full 300 RPM. Visible mechanics for learning: Transparent dualflow casing exposes synchronized turbine and piston movements for STEM analysis and classroom explanation. Practical assembly learning: Prograde DIY kit includes CNCmachined alloy mounts and a stepbystep manual that teaches core aerospace engineering concepts through handson construction.

Trade show or museum display: Run continuous demos with adjustable speed and LED afterburner effects to show visitors the mechanical principles behind turbofan engines. Hobbyist build and display: Assemble the 28 cm model as a centerpiece for a workshop or collection, and use the precision slider to show realistic engine response during demonstrations. Why this kit stands out Combines realistic visual effects and accurate motion with a rechargeable, allinone power system that supports extended demonstrations. Built from reinforced materials and precision hardware to deliver smooth operation at full speed and longterm reliability. Includes educational documentation and components that make assembly instructive rather than purely decorative. Compatibility and notes Designed as a scale model and educational demonstration device for the A380 TR900 turbofan engine design. Not intended for propulsion use. Uses TypeC charging. Follow the included manual for safe charging and battery care. This kit is suitable for educators, hobbyists, model builders, and anyone seeking a reliable, realistic turbofan engine replica for teaching or display.
