RAF-11 and RAF-11bis by A.N.Rafaelants

48k b/w "History of aircraft construction in the USSR", Vol.1 p.572

Low-wing 2-engine wooden monoplane. Semi-monocoque fuselage provided room for 6 passengers. Retractable landing gear had main hydraulic and pneumatic emergency systems. Two-spar wing with fabric skin. Both aircraft were built at the GVF repair workshop.

RAF-11 was flown in 1938. Despite very clean shapes, aircraft was overweight and showed sluggish performance. Improved RAF-11bis was flight-tested in 1940. It was found successful and recomended for production as passenger for second class (??) airlines, trainer and 'transitional' (advanced trainer) aircraft.

Despite positive trials outcome, RAF-11 did not enter series production.
