GY.20


M. Yves Gardan designed the GY 201 Minicab in 1949 as a two seater with side by side seating and dual control, which first flew in 1949. The fuselage is a wooden open girder structure; the forward part around the cockpit being plywood lined, the remainder fabric covered. The fin is built integral with the fuselage. The tailplane is a single piece plywood covered structure, and the elevator and rudder have fabric covered wooden frames. The wing section is NACA 23015 at the root and 23010 at the tip. The wing structure consists of a laminated spruce and plywood main box spar, a diagonal drag spar and a rear false spar, with lattice type ribs. Forward of the main spar is plywood covered to form a torsion box, the remainder of the wing being fabric covered. Split flaps are installed. The two main undercarriage legs are mounted on the main spar with rubber in compression springing. An 11 Imp. gallon fuel tank is fitted just behind the firewall.


In 1949 his GY-20 Minicab won the world record for speed and distance in a straight line for an aircraft of less than 1102 lb (500kg) maximum gross weight, flying from Paris to Rabat in 10h of flight, 1135 mile being covered at 109mph average (1826km at 185kph) with a Continental 65hp motor. More than 100 Minicabs were made and it is still being built by US homebuilders under the name of Cavalier in 1983.


In 1952, the 90hp version of the Minicab appeared, with retractable undercarriage and called the Super-Cab. Continental engines from 65 to 100 h.p. may be installed.

Production was entrusted to the Constructions Aernautiques du Bearn, which delivered the first aircraft in 1952, and support for this light type subsequently passed to SIPA (the Société Industrielle Pour l’Aeronautique). There were two production variants of the Minicab, the GY.20 and GY.201, these differing from each other only in details of equipment and other small features.

 

GAB-Supercab
One of the French G.A.B. Supercabs undergoing fully-instrumented
test flying at Villacoublay; Jacques Noetinger is the pilot.


Produced in limited numbers between 1952 and 1958, the design was acquired by A.W. Ord-Hume in Britain, who anglicised the plans. Adjusted them for home builders, the aircraft has subesequently proved extremely popular. The aircraft is marketed in North America as the Hawk BM.4 by Miranda Aircraft of Canada.
