Mould King 10212 Motorized Rotary Engine Model Building Set | 1,130 Pcs

Inspired by legendary 13B Wankel engine, this 1130-piece set brings the unique triangular rotor design to life.

The model features a compact and precise structure that reflects the rotary engine’s real-world advantage: high revs in a small footprint. The intricate gear and chain drive system powers a large cooling fan at the front, simulating the motion of the rotors inside the housing.

Equipped with a motor and battery pack, the engine comes alive at the flip of a switch. You can watch the internal mechanics rotate in both forward and reverse directions, adding dynamic realism.

For added interactivity, the model includes a 4-speed gearbox (low, medium, high, and hyper speed). This allows you to experience the smooth transition from steady rotation to the thrilling speed of a high-revving rotary engine.

Whether displayed on your desk or used as a teaching model for engine mechanics, this rotary engine block set offers a perfect mix of play, education, and mechanical beauty.
