GNOSSPELIUS hydro-biplane
After receiving Aviators Certificate No.360 in March 1912, the first to be issued to a pilot trained on a hydro-aeroplane, Lt. Trotter ordered a two-seater biplane to be designed by Gnosspelius. The machine was launched by the 8 September 1913, but did not takeoff until 20 September 1913, when Trotter alighted heavily immediately after lifting off and damaged the chassis and propeller. After repairs and a change of main float, only limited flying took place due to various problems, the machine apparently being flown for the last time on 11 November 1913.
The four-bladed propeller was geared down by chain and sprockets from the 100hp Green, six-cylinder inline, water-cooled engine, which was not powerful enough for the heavy aircraft that Gnosspelius had designed. A large radiator was mounted alongside the passenger seat on the port side. The three bay wings had ailerons on the top plane only. No fin was fitted and the rudder post extended down to carry a water rudder.

Gnosspelius Hydro-biplane
The Gnosspelius two-seat tractor hydro-biplane was designed by Oscar T. Gnosspelius and was built during 1913. It was powered by the 100 h.p. Green engine with which it flew at Lake Windermere in September, 1913, piloted by Lt. J. F. A. Trotter. The machine was found to be underpowered during testing.
