Aircraft program
Two-seat high-wing light plane. Includes variants AC4 UL (formerly AC4-UL6) for the European ultralight category 600kg, AC4 CS-LSA (LSA certified) and the AC4 CS-LSA GT (same as LSA but for glider towing).
The aircraft as engineered: what it is built from, the systems it flies with, and its configuration — each box a theme.
Technical reference compiled with AI research; a value appears only where two independent research passes and a web fact-check agree. Gaps are deliberate.
