Tipsy B
The Tipsy B was a small sports two-seat monoplane designed by Ernest Oscar Tips, and built in both Belgium and the UK. A total of 42 was built, and a few are still flying.
Avions Fairey, the Fairey Aviation Company's Belgian subsidiary, was set up in 1930–1 to produce Fairey Fox and Firefly aircraft for the Belgian Air Force. Once production of the military aircraft was under way, its manager Ernest Oscar Tips found the time to design and build light aircraft of his own, first the single-seat Tipsy S and S.2 in 1935, then the two-seat Tipsy B. Although the latter was larger, the two aircraft types had much in common; both were single-engined low wing cantilever monoplanes, with wings tapered on the trailing edges. In detail, though, the planforms of the two aircraft were different. Both were built in Belgium by Avions Fairey and in the UK under licence.
The Tipsy B was a wooden framed machine, covered with a mixture of plywood and canvas. The wing had an I-section main spar at about one quarter chord and an auxiliary rear box spar. These were linked by a rigid diagonal pyramid bracing. Stressed plywood skin was used from the main spar forward, with the rest of the wing fabric covered over wooden ribs. The leading edge was almost straight, and the trailing edge straight but strongly forward swept except at the centre section. Differential ailerons were carried on the tapering section, so their hinge line was also strongly forward swept.
The flat sided fuselage had four spruce longerons, and was plywood covered apart from a rounded decking. The depth of the decking behind the cockpit depended on whether the seating was open or closed. The Tipsy B had an open cockpit, with almost side-by-side seating in the sense that the seats were slightly staggered fore and aft to minimise fuselage width, with the left hand seat 8in (200 mm) further forward. The Tipsy Bc had the same seat arrangement, but enclosed under a Rhodoid (cellulose acetate) canopy, faired into the fuselage rearwards by a much deeper decking. Some Tipsy Bs had an asymmetric windscreen formed out of a single Rhodoid sheet, with its free edge further forward on the left to match the displaced seating, but symmetrical screens became common. Dual controls were fitted. The control column was on the mid-line between the seats, with a horizontal extension that could be rotated over either position. A 60 hp (45 kW) Walter Mikron four cylinder inverted in-line engine drove a two-bladed propeller.
The fin was almost triangular, and built as an integral part of the fuselage. The fabric covered rudder was rounded, and moved between the separate elevators, which with the tail plane formed an elliptical shape. As a result, the elevator hinges, like those of the ailerons were strongly forward swept. The tailplane was braced to the fin near the rudder post with a pair of struts. There was a long tailskid. The main undercarriage had two cantilever forks with rubber-in-compression springing, its legs faired and the wheels spatted.
On 8 May 1937, the Tipsy B first flew from the Avions Fairey factory airfield at Gosselies, near Charleroi, with A.J.Eyskens at the controls. A week later, the Tipsy was being demonstrated in the UK at Great West Aerodrome. On 5 June 1937, the Tipsy Light Aircraft Company of London Air Park, Hanworth was established to build the Tipsy B under licence.
In total, twenty-four Tipsy B and Bc aircraft were built at Avions Fairey before the invasion of Belgium by Germany in World War II. About eight had open cockpits (Tipsy B) and the rest were enclosed (Tipsy Bc).
The Tipsy seems to have been mostly nice to fly but, as with other aircraft with pointed wing tips, its low speed behaviour could be unforgiving, dropping a wing at the stall without much warning. Some of these issues were addressed during the British production run, .
