FS2004/FSX Yak-11 racer CZECH
FS2004/FSX Yak-11 racer CZECH MATE Hanging a big American engine on the front of a relatively small airframe like the Yak- 11,a former Soviet Yak-11 trainer makes this diminutive Russian trainer go very fast indeed.The engine of choice in this particular version is the tried and true, Pratt & Whitney R-2800, 18 cylinder radial engine. This engine, first produced in 1939, was rated at 2000 hp @2400 RPM. Improvements in fuel octane, and the engine itself, finally brought the output to 2400-2600 hp depending on the version. These outputs are based on maximum RPM and time limits of 2800 RPM at 60 inches of manifold pressure, limited to 5 minutes take-off power rating. In Czech Mate this engine is pushed at over 3000 RPM and “around” 80 inches of manifold pressure. A F Scrubb
