RealEngine v1.4 fails engines and systems of piston engine aircraft if operating limitations are exceeded. Limitations modeled: MP / RPM / power, CHT, Oil Temp, Oil Press, Lean/Rich roughness, Spark Plug Fouling, Gear/Flaps Overspeed. Added vs v1.1/1.2: Easier configuration, realistic CHT Model, Mini Status Panel. Can be fully configured for individual aircraft. By Gunter teson1.
