Aircraft program
Kitbuilt single piston engine aerobatic biplane.

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.
