The IAR-811 was designed by a team of designers at the Sovromtractor tractor factory at Brașov (formerly the Industria Aeronautică Română aircraft works) in 1949. It was a single-engined low-wing monoplane of all wooden construction. Its crew sat side by side under an enclosed canopy, and the aircraft was powered by a single 45 kW (60 hp) Train 6T engine. The only example made its first flight on 12 May 1949.[3] It was claimed to be very manoeuvrable, and have good handling, and it was reported that consideration was given to putting the type into production,[2] but the engine was no longer in production. The aircraft was developed into the IAR-813, which used the available and more powerful (120 kW (160 hp) Walter Minor 4 engine.[4]
