The Kermansky Special
You better be wearing your brown pants for this one. The K-Special is a Stunt Biplane powered by an inline Kontra-Rotating Turboprop. She has enough power to climb vertically at about 30m/s. At 5000m the KRP-111 can top out at 100m/s. Top speed ever recorded while diving was 130m/s. Inspired by the vintage Grumman FF carrier fighter, the K-Special has better maneuverability and higher top speed likely due to the contra-rotating props.
Incredibly stable at high G’s and high speeds, watch out for Yaw stalls and the occasional random explosion. Land-able without power or with only 1 working engine.Gfycat HD GIF
