"Oberursel UR.2 - The First WW1 production engine in 90 years!"
Nearly a year of development and construction has produced this airworthy reproduction WW1 Rotary engine. Our Oberursel UR.2 has begun it’s test program and this video shows it running or more appropriately, spinning. The unique way these engines operate is a sight to behold, nearly 350 lbs of engine becomes a rotating blur.
