Maybe the "Hiper" was a language barrier thing.
The "super" did have a different wing, longer it was, with squared off wing tips. Flush rivets on the wing surface. It had gear doors, retractable tail wheel, taller different tail, probably for bigger rudder for the bigger engines instaled, Curtis Wright, 1820-76 i believe. larger payload, longer range.
Or maybe the Hiper thing was a design that never made it into production.
