British Aerial Transport Low Volume Production

Two seat elementary training, two bay biplane to Specification A.2(d). The aircraft was designed for extreme simplicity and ease of construction. The fuselage was a simple wooden box structure, plywood covered and with a rounded top structure. Upper and lower mainplanes were interchangeable, and ailerons, elevators and the rudder were all identical. The rugged, sprung undercarriage was mounted on V-members located below the inner interplane struts, with a single transverse bracing strut to the aircraft centreline. One 170 h.p. A.B.C. Wasp powerplant was mounted, uncowled, on the fuelage engine mounting plate, and gravity fed from a fuel tank located under the upper starboard wing in the middle of the first bay.

Single seat two-bay fighter biplane to Specification RAF Type I. The aircraft featured a semi-monocoque fuselage and equal span, unstaggered wings, with dihedral on the bottom planes only. Ailerons were fitted on both wings, plain on the first machine and horn balanced on the second and third. Armament was two forward firing, synchronised Vickers .303 machine guns mounted ahead of the pilot, and enclosed in a large fairing that formed the upper coaming of the pilot's cockpit. One 320 h.p. A.B.C. Dragonfly powerplant.

Two-seat sporting biplane derived from the F.K.23 Bantam. The aircraft featured side-by-side seating staggered en echelon to starboard. The two bay sesquiplane wings were arranged conventionally, with the lower mainplane attached to the bottom of the fuselage and the upper mainplane supported on cabane struts above the fuselage and solid built up inter-plane struts. The fixed under-carriage consisted of strut supported main-wheels and a sprung tailskid at the rear extremity of the fuselage. One 200 h.p. A.B.C. Wasp II powerplant.

Single seat Demoiselle type ultra-light. A cantilever monoplane with no external bracing, the wings were tapered from root to tip, and fitted with ailerons for lateral control. The fuel tank was mounted on top of the plane, divided laterally, the oil being contained in the smaller front part, while the rear portion of the tank contained fuel. Two tail booms, also cantilever beams, of built-up rectangular section, carried the tail surfaces at their rear end, and in front were bolted to the wing spars. There was a small symmetrical tail plane and a divided elevator. The vertical fin and rudder extended above and below the tailplane. The pilot was seated below the wings in a wicker-bound basket-type bucket seat, with arms, located in a small nacelle carried on six circular section steel tubes coming down from the wings. Passing through the bottom of the nacelle was a flat laminated spring of wood, with short stub axles for the rather large wheels. A nose pitot tube was fitted. One 40 h.p. A.B.C. Gnat powerplant mounted on the leading edge of the wing, and driving a small Ebora tractor propeller.
