This technical kit guides you step by step through building a functional engine model powered by a rechargeable battery. Thanks to the well-thought-out design, you will see in practice how the piston, timing belt, and flywheel work, and how energy is transferred in mechanisms.

It includes numbered bags for easy sorting, a USB charging cable, and a clear illustrated manual. The striking red light gives the model an impressive look and highlights the moving parts.

• Realistic piston and cylinder operation – a clear demonstration of the combustion cycle.
• Timing belt drive – understand energy transfer between components.
• Throttle valve/flap – shows flow regulation in the model.
• Red light – an eye-catching detail for added realism.
• Flywheel – accumulation and release of kinetic energy during rotation.

Notice: Charge the battery for at least 2 hours before first use.
