Flight, December 1937

BUILT at LYMPNE
A Creditable "Home-made” Effort by a Ground Engineer

   A CURRENT topic of conversation in club flying circles is "that little biplane built by the Lympne G.E." The G.E. concerned is Mr. Currie and his aeroplane has been tentatively christened The Wot.
   The little single-seater biplane is of simple construction and is built of spruce and plywood with mild steel fittings throughout..
   The fuselage has four spruce longerons and cross-members with plywood sides and decking. There are three stiffening plywood bulkheads and a fireproof bulkhead. A locker is incorporated in the top decking behind the pilot.
   Two solid rectangular spruce spars are used for each wing, and there are three bays of wooden bracing. Eleven main ribs and nine nose ribs are used with a plywood leading edge and spruce trailing edge and tip. The interplane struts are of spruce. Two landing wires, two flying wires and two interplane strut cross-bracing wires figure in each pair of wings. The centre section consists of six faired, mild-steel tubular struts braced by two pairs of wires.
   Situated in the fuselage between the pilot and engine is a six-gallon tank. There is plenty of room for additional tankage.
   Controls are of orthodox design and include differential ailerons. The differential action is in a small box under the pilot's seat.
   The undercarriage consists of two pairs of faired tubular legs to the bottom of which are welded two horizontal tubes. This structure is braced by a pair of wires.
   The streamline axle is held by "bungee" cord. Low-pressure tyres are used.
   The engine - a J.A.P. flat twin of 36 h.p. - is mounted on mild-steel-tube bearers which are, in turn, mounted on rubber to absorb vibration
