The Radley-England Waterplane was a British floatplane designed and built by James Radley and Gordon England to take place in the 1913 Circuit of Britain race. Damaged before the start of the race, it was unable to compete and was subsequently rebuilt as the Radley-England Waterplane 2[1] Design and developmentThe Radley-England Waterplane was a four-bay biplane with ailerons fitted to the top wing only. A single horizontal stabiliser and elevator with twin balanced rudders mounted below it were carried on four wire-braced booms behind the wing. The crew and passengers were carried in a pair of flat-bottomed floats suspended on struts underneath the lower wing. It was powered by three 50 hp (37 kW) Gnome Omega rotary engines arranged in line above the wing centre section, each connected by a roller chain to a long shaft at the rear of which was a four-bladed propeller 9 ft 10 in (3 m) diameter. To protect the occupants from the oil thrown out, the front engine was partially enclosed by an aluminium cowling.[1] A number of successful flights were made at Huntingdon in April 1913 with Gordon England at the controls,[2] using a temporary wheeled undercarriage. It was then taken to Shoreham for further trials. During these England ran over a buoy when landing, tearing the bottom out of one of the floats.[1] The aircraft was subsequently rebuilt in a modified form. The flat bottomed hulls were replaced with a pair of clinker-built hulls made by the South Coast Yacht Agency of Shoreham, each with a pair of tandem cockpits; the Gnome engines were replaced by a single {{convert|150|hp|kW|abbr=on}} Sunbeam 150hp water-cooled engine driving a slightly smaller propeller and wing area was increased by slightly increasing the span of the upper wing.[1] Specifications (Waterplane 2){{Aircraft specs|ref=British Aircraft 1809-1914[1] |prime units?=imp |genhide= |crew=2 |capacity=2 |length m= |length ft=29 |length in=9 |span m= |span ft=51 |span in=7.5 |height m= |height ft= |height in= |wing area sqm= |wing area sqft=560 |empty weight kg= |empty weight lb= |gross weight kg= |gross weight lb=2500 |eng1 number=1 |eng1 name=Sunbeam 150hp |eng1 type= V-8 water cooled side-valve piston engine |eng1 hp=150 |prop blade number=4 |prop name=Lang |prop dia m= |prop dia ft=9 |prop dia in=6 |max speed kmh= |max speed mph= |cruise speed kmh= |cruise speed mph=60 |range km= |range miles= |endurance=10 hours |ceiling m= |ceiling ft= |climb rate ms= |climb rate ftmin= |perfhide = }} Notes1. ^1 2 3 4 5 6 7 {{cite book|last=Lewis|first=Peter|title=British Aircraft 1809-1914|year=1962|publisher=Putnam|location=London|pages=408–409}} 2. ^{{cite journal|title=Testing the Radley-England Hydro-Aeroplane|journal=Flight|date=19 April 1913|url=http://www.flightglobal.com/pdfarchive/view/1913/1913%20-%200425.html|accessdate=31 December 2012}} References
