The Davis-Costin Condor was a conventional all-wood, tandem-seat sailplane built in the United Kingdom in the 1950s.
The wing was built around two spars and the planform was unusual in that the chord of the straight tapered inboard section increased outwards.
A skid from the nose ended under the wing with a small monowheel; a little tailwheel was fixed below the rudder hinge.
The fuselage was lengthened by 8 in (203 mm), chiefly by moving the cockpit further forward, at the cost of a 7 lb (3.2 kg) increase in weight.
The trailing edge of the rudder was curved outwards and a very small dorsal fillet added.
