| F — Fuselage | Very narrow ply-covered fin integral with the fuselage |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Cantilever high wing mounted on a streamlined central pylon
- Rectangular centre section with trapezoidal outer panels
- Very narrow ply-covered fin integral with the fuselage
It is an all-wood glider with a plywood-skinned semi-monocoque fuselage and an enclosed cockpit ahead of the wing pylon. The wing is plywood covered around the leading edge and fabric covered elsewhere.
Specifications
- The Grzeszczyk SG-3 has a length of 7.05 m (23 ft).
- It has a wingspan of 17 m (56 ft).
- Typical crew: 1.

History
Szczepan Grzeszczyk began the design in 1932, and Warsztaty Szybowcowe began three developmental airframes in March 1933. The first flew in July or August 1933.
Variants
The SG-3 was built in batches in 1934 and 1935. The SG-3bis of 1936 had a gull wing of constant taper and a longer span.
Where you'll see it
Between 1934 and 1937 it was Poland's most successful competitor and record setter. Twelve competed in the 1936 National Glider Contest, where the SG-3bis dominated. In 1938 Wanda Modlibowska set a women's distance record of 343 km.
