It was, though, structurally cleaner and simpler to rig, with most flying wires replaced by faired, steel V-form bracing struts and an empennage supported on a simple box beam rather than an extended central frame.

There was only one bracing wire on each side, running from the top of the forward wing strut to the centre of the upper fuselage just aft of the trailing edge.

It was mounted above the fuselage on a trapezoidal frame formed from three struts in a distorted, inverted N-shaped arrangement, the rear member sloping shallowly aft.

The completely exposed pilot's seat was on the upper surface of the forward end of the beam, just under the leading edge, where a narrower forward extension carried the rudder bar and, on its underside, the front end of a landing skid that reached below and behind the pilot.

[1] The BS.7 was designed with transportability in mind and, with the wings detached and arranged along the fuselage beam, leading edges up, it could be towed behind a motorcycle on a two-wheeled trailer.
