Recognition (WEFT)
| W — Wings | High-mounted, tapered |
|---|---|
| E — Engines | 1 × none, embedded-mounted |
| F — Fuselage | Cantilever high gull wing carried on a faired pylon above the fuselage |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Cantilever high gull wing carried on a faired pylon above the fuselage
- Oval-section plywood fuselage with an enclosed cockpit ahead of the pylon
- Narrow tailplane mounted a little above the fuselage on a narrow fin
It is a wooden sailplane with a two-part cantilever high gull wing, trapezoidal in plan with rounded tips. The wing sits on a faired pylon above an oval-section plywood fuselage.

History
The SG-7 was a development of the SG-3 with reduced dimensions, designed during 1936-7 to meet a government call for a high performance sailplane. It first flew in the late spring of 1937, and a second airframe followed in July.
Variants
Only two prototypes were built and there were no production versions.
Where you'll see it
One SG-7 appeared at the 1937 Scout Jamboree in the Netherlands, and the other finished 26th at the Fifth National Glider Contest in Inowroclaw. Both stayed in use until 1939.
