The Bücker Bü 134 was a side-by-side twoseat light cabin monoplane in a similar category to the Taylor Cub and intended for club and school use, the sole prototype of which (D-EQPA) was flown in 1936. Powered by a 105 hp Hirth HM 504 inverted four-cylinder inline aircooled engine, the Bü 134 was of mixed construction with a chrome-molybdenum steel tube fuselage and wooden wings and tail surfaces.
