| F — Fuselage | Single-seat high-wing glider with an open frame, uncovered flat girder fuselage |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Single-seat high-wing glider with an open frame, uncovered flat girder fuselage
- Rectangular two-part wing with blunted, angled tips
- Narrow triangular tailplane and fin
The wing is braced on each side by a short steel tube and a longitudinal N-strut, and the trapezoidal ailerons cover over half the span.
Specifications
- The WS Czajka has a length of 6 m (20 ft).
- It has a wingspan of 11.3 m (37 ft).
- Its maximum speed is 169 km/h (105 mph).
- Typical crew: 1.

History
Antoni Kocjan designed it in 1931 at the workshops of the Mechanic Students' Club of Warsaw University of Technology at Okęcie. It was intended to bridge the gap between basic trainers and high-performance sailplanes. The first of three government-ordered prototypes flew in 1931.
Variants
There were four major variants, the Czajka I, II, III and the 1936 Czajka bis, which mostly differed in pilot accommodation.
Where you'll see it
More than 160 were completed. Eighteen were built at Okęcie, and further production moved to Warsztaty Szybowcowe in Warsaw in 1932.
