The Gribovsky G-5 ({{lang-ru|Грибовский Г-5}}) was a small, low powered Russian single seat sports aircraft from the late 1920s. Design and developmentThe G-5 was the first powered Gribovsky aircraft to fly; his first three designs were gliders and the first powered type, the Gribovsky G-4, though built, was not flown. Structurally all of his aircraft were wooden and several had smooth, rounded monocoque fuselages. That of the G-5 was oval in cross-section, with a single, open cockpit. Its low, cantilever wing had a high aspect ratio (9.0) for the time and the rear surfaces were also high aspect ratio. All flying surfaces were unbraced, keeping the G-5 aerodynamically clean, and the only external bracing was for the main landing gear. The G-5 was powered by a small British V-twin, the {{convert|18|hp|kW|abbr=on|0}} Blackburne Tomtit,[ an engine which had been installed in several of the aircraft that competed in the first Lympne light aircraft trials of 1923, mostly running inverted.[2]] Specifications{{Aircraft specs
