WINDHAM tandem monoplane No.1

   This unusual looking machine appeared at Wembley Park in August 1909, being first reported as under construction in June, thus succeeding the de Pischoff machine, which may already have been abandoned. Although the design was described at the time as 'ingenious' the machine was not capable of flight. The machine consisted of single top and bottom longerons of bamboo, spaced by vertical struts and braced by wires. Extending from the top longeron were single spars of bamboo for the front and rear wings, which were set at a pronounced dihedral angle. The wings were merely diamond shaped panels of fabric, laced to wire leading and trailing edges. Set below the wings, were long triangular shaped panels provided as fins. A small square elevator and a rudder were fitted at the extreme rear. The undercarriage consisted of two pairs of wheels, mounted separately, below each wing spar.
   The engine was mounted at the front driving a tractor propeller and was cooled by a circular radiator, as used on the earlier biplane, but mounted end-on to the airflow, above the front wing spar. The pilot apparently sat on the lower longeron.

   Power: 35/45hp Dutheil-Chalmers four-cylinder horizontally opposed water-cooled.
