1/32 Oberursel U.0

The Oberursel U.0 engine is a pioneering rotary engine known for its lightweight design and reliable performance, playing a crucial role in the early days of aviation. Developed in Germany by Oberursel, this seven-cylinder air-cooled rotary engine was modeled after the Gnome Lambda engine and became a foundational power source for some early aircraft, particularly in the pre-World War I era. With a displacement of approximately 12 liters, the U.0 generated around 80 horsepower, making it suitable for small, maneuverable aircraft used by aviators exploring the frontiers of flight.

The U.0's unique rotary design meant that the entire engine spun with the propeller, aiding cooling and simplifying engine construction by eliminating the need for a water-cooling system. This design allowed aircraft equipped with the U.0 to achieve agile handling, which was especially valued in aerial competitions and early combat scenarios. Today, the Oberursel U.0 is an admired piece of aviation history, appreciated by collectors and aviation enthusiasts.
