of the outer bay of each wing was extended aft to form flexible extensions to effect lateral control: between the tips of these extensions, four balanced rudders were pivoted. The undercarriage consisted of a pair of ash skids extending forward, almost as far as the elevators. No wheels were fitted, as it was intended to use a launching rail for takeoff. Apart from the skids, the entire airframe was built of

. This was arranged so that both propellers revolved in the same direction, since crossing them to make them revolve in opposite directions might have infringed patents held by the Wright brothers. Work continued at the newly established Short Brothers works on the Isle of Sheppey, and was complete upon McClean's return from China. The Bariquand et Marre engine was not yet available, so a engine taken from a Nordenfelt car was installed. However, at more than in weight, when a first attempt at flight was made in September, the engine failed to propel the machine even as far as the end of the launching rail. The Bariquand et Marre engine arrived in October, and McClean made three attempts at flight on 2, 3 and 6 November, almost succeeding in becoming airborne, but on the last attempt he applied full up-elevator, and the machine stalled and fell back on the launch rail, breaking the undercarriage and propellers: it was not repaired.Barnes 1967, p.43 McClean's next aircraft was a copy of the Wright Model A built under license by Short Brothers.
