Recognition (WEFT)

W — Wings	High-mounted, straight
E — Engines	1 × piston, nose-mounted
F — Fuselage	Each wing supported by a pair of inclined struts to the fuselage, with rounded wingtips
T — Tail	Conventional

WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

Single-seat braced high-wing monoplane
Each wing supported by a pair of inclined struts to the fuselage, with rounded wingtips
Fixed landing gear made entirely of steel tube

Look for a small braced high-wing monoplane with a pair of inclined struts under each wing and rounded wingtips. It has a plywood-covered fuselage of elliptical cross-section and a fixed steel-tube undercarriage.

History

It was developed from the SIM-X, with a more powerful engine fitted with a carburettor for inverted flight, a smaller wing area and a more flexible structure. Sima Milutinović was consulted in 1937, and the first test flight was made by Captain Milan Bjelanović in January 1938.

Variants

Only one SIM-XI was built, as the prototype was bought by the Royal Yugoslav Air Force and no production followed.

Where you'll see it

The air force judged its existing PVT and R-100 trainers sufficient, so the type was not produced. The sole aircraft was captured in 1941, passed to the Independent State of Croatia and used for glider towing until it was destroyed in 1943.
