Background
The Avro Biplane was the first biplane design built by A. V. Roe. It was a further development of his previous designs, which featured tri-plane layouts. I remember an Avro tri-plane in this series but its not been reissued. The design shared some common features with the other aircraft of the day. A triangular shaped fuselage was large enough for a pilot and passenger. The increased surface area of two wing surfaces handled the extra weight. Wing warping was used to turn the aircraft. What set this design apart was the 35 HP water-cooled engine built by the Green company. A cooling system helped provide reliable power over long durations, something that plagued other aircraft engines.
