FS98 Avro Roe-II Triplane, 1910. The successor to the Roe-I Triplane, the "Mercury", was built by Alliot Verdon Roe, the founder of Avro. This model was powered by a more powerful 4-cylinder 35 hp Green engine, and flew in Brooklands in 1910 at a speed of 35 knots. It had a sturdier airframe, and pitch control was improved by pivoting the entire tailplane, being linked to the mainplane variable incidence gear. Wing warping was abandoned, instead of which a pair of large ailerons fitted to the top wings catered for lateral control. The rudder was also taller, with twice the surface. By Stephan Scholz.
