CLARKE monoplane

   This is the only Clarke powered aircraft of which information exists, as it was described in The Aeronautical Journal of October 1910, having won a prize for its design in a competition. It was for Clarke's own use, and was reported to be nearly ready for trial, probably at Brooklands. No reports of trials or successful flights appeared. The machine was a canard with a monoplane foreplane serving as elevator and with a front mounted rudder. Lateral control was by warping the wing.

   Power: 25/30hp Thames four-cylinder horizontally opposed water-cooled driving a 7ft 6in diameter Clarke propeller.
