MouldKing® Rotary Engine

Inspired by the legendary 13B rotary engine, this set brings the unique triangular rotor design to life. The model features a compact and precise structure that reflects the real-world advantage of the rotary engine: high RPMs in a small space. The complex gear and chain drive system powers a large fan at the front, simulating the movement of the rotors within the housing.

Equipped with a motor and battery compartment, the engine comes to life at the touch of a button. You can watch the internal mechanisms rotate both forward and backward, ensuring 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 exciting speed of a high-revving rotary engine.

Whether displayed on a desk as a showcase piece or used as an educational model for engine mechanics, this rotary engine set offers the perfect blend of playfulness, education, and mechanical beauty.
