Aircraft program
Single piston light aircraft family. Including 2 seat and 4 seat kit variants. Formerly Sling Aircraft Sling Series.
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.
