Recognition (WEFT)
| W — Wings | High-mounted, elliptical |
|---|---|
| E — Engines | 1 × piston, nose-mounted |
| F — Fuselage | High-wing monoplane with elliptical wings braced to the lower fuselage |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- High-wing monoplane with elliptical wings braced to the lower fuselage
- Welded steel-tube fuselage and wings clad in light-alloy sheet, with fabric-covered control surfaces
- Fixed undercarriage on a continuous axle, with a sprung tailspur and a closed pilot cabin
It looks like the K-1 but is clad in metal, a high-wing monoplane with elliptical wings and a closed pilot cabin.

History
Kalinin planned it at the yard of the airline Ukrvozdukhput, which was renamed GROS. It was more complex to assemble than the K-1 and its construction weight considerably exceeded the plan. It was powered by a BMW IV six-cylinder inline engine.
Variants
The K-3 was an ambulance variant of the K-2 with room for one doctor and two stretcher patients, or four seated patients.
Where you'll see it
It was used by Ukrvozdukhput. Only a handful were built, four according to the article text.
