Background History:

The appearance of the German turbojet-powered Messerschmitt Me 262 near the end of World War II prompted the Soviet Union to develop faster fighter aircraft. Since the USSR lacked a production-ready turbojet engine, development efforts were directed toward mixed-power aircraft utilizing a conventional piston engine-driven propeller for the majority of propulsion with a small rocket or jet engine for bursts of speed.[1]

The Su-5 (initially I-107) and the conceptually similar Mikoyan-Gurevich I-250 were designed in 1944. The aircraft first flew on 6 April 1945 and underwent limited flight testing. It was subsequently fitted with a laminar flow wing and attained 793 km/h (428 kn, 493 mph) at 4,350 m (14,270 ft) with the motorjet functioning.

How to fly

TURN ON AG1 (for prop engine) and AG2 (for Jet engine)
You can use only one engine or both for a better speed and stability. Use trim slightly, to correct the level flight.
