Two streamlined pylons joined the wings to the box, above and below, carrying the fuselage at mid gap. For the aerodynamic investigations, the untapered part of the fuselage could be contained in circular fairings of different diameters; originally a range of five sizes was planned, but to reduce cost only the smallest (3 ft (91 cm)) and largest (5 ft (150 cm)) were flown. Since the diameter of the Jupiter was about 4 ft 7 in (1.40 m), the cylinder heads were well exposed with the smaller fairing and enclosed by the larger.

Barnwell's response was again to design a full-scale aircraft which had the simplifications of a typical wind tunnel model, to which could be fitted any of several cowlings over the
Jupiter engine; the Type 92 was the result. It was a two-bay biplane without

By the end of the 1920s, the problem of cowling radial engines was beginning to be mastered, though it is not clear how much the Type 92 contributed to the solution. In 1929, the
