Yes, that mention of CAP-1 derivatives is repeated in several online references but never with any details about the CAP-2 :(

Possibly off-topic but Empresa Aeronáutica Ypiranga began by building the EAY-101 glider in 1931. The prototype EAY-201 Ypiranga first flew in 1935 with a 40 hp Salmson 9 AD ... but there was no change in designation when the French radial was replaced by a 65 hp Franklin 4AC-176-B.

BTW, does anyone know if the CAP-1A was the modified prototype Planalto fitted with a 130 hp Franklin also known as the 'Tufão' (Typhoon)?
