The 1922 Hi-Lift was an experiment by Sperry in modifying a Curtiss JN-4D into a monoplane with an internally-braced, one-piece high-wing with I-beam spars, to produce a craft capable of carrying five, when it was originally designed for two. Despite successful trials and demonstrations, nothing came of the idea.
