Recognition (WEFT)
| W — Wings | Mid-mounted, straight |
|---|---|
| E — Engines | 1 × piston, nose-mounted |
| F — Fuselage | 5.3 m fuselage |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Sesquiplane whose lower wing has almost the span of the upper but only 60 per cent of its chord
- Single bay with extreme stagger and one forward-leaning interplane strut each side
- Duralumin airframe with a bulbous underside housing a large fuel tank
A small tandem two-seat sesquiplane with the upper wing held over the fuselage on a cabane and a cut-out in its trailing edge for the front seat.

History
Bolesław Skraba, a flight instructor and test pilot, built it as a private initiative to attempt a Polish aircraft range record. The first flights used a 45 hp Anzani engine because the intended Salmson 9AD arrived late.
Variants
There were no variants: only one was completed.
Where you'll see it
It remained a one-off. Endurance with maximum fuel was 15 hours.
