With the "Fast Build" option, the ribs and spars are laminated to the bottom skin at the factory.

Before installing the top skin, fuel tanks are built into the leading edge, rib caps are installed, and a simple aileron push-pull tube bellcrank is installed.

Most builders also laminate a VOR antenna to the inside of the bottom skin.

This photo shows a Comp Air 6 optional taper wing ready for installation of the top skin.

An easy-to-assemble high-lift constant-chord wing with molded ribs is standard on the CA4 & CA6. The taper wing is standard on high performance models (CA7/8/10).
