 This revision retained the original design's size and configuration, however, it was powered by a special, two-stage supercharged Pegasus engine and, although remaining basically a single-seater aircraft, had made provision for an observer's cockpit to be installed if deemed to be required.The use of the Pegasus engine on the proposed aircraft was viewed as being positive for gaining publicity and thus fostering wider sales.As a weight reduction measure, the original retractable undercarriage arrangement was replaced with a lightweight, fixed counterpart instead.
