WATSON biplane No.2
An improved version built on the same general lines as No. 1 appeared in 1910. The revised center structure was mounted on a four wheeled undercarriage, and bracing struts were added below the lower wings. The engine was a 30hp Humber three-cylinder, air-cooled, fan type semi-radial driving a tractor propeller. The boxkite tailplane, which was first fitted, was later changed for a monoplane with elevator, and a triangular portion of each of the tail booms was filled in to provide vertical surface area.
In this latter form the machine was known to have been flying at Errol, Perthshire in 1912.

Watson Biplane No. 2
The second biplane designed by Preston Watson to incorporate his tilting upper wings appeared in 1910 and was fitted with a three-cylinder Humber engine of 30 h.p. It was an improved version of the first machine, and was fitted with a four-wheel undercarriage and bracing struts to the tips of the lower wings' underside. Further modifications were made, which consisted of fitting a new monoplane horizontal tail without end fins, side area at the rear being embodied by filling in between the booms at the rear. In this form the Watson No. 2 was flying at Errol, Perthshire, during 1912.
