Wisenant Airplane
A 1920 experimental single place, open cockpit mid-wing monoplane with wings mounted in a folded-back manner above two outboard 7' propellers, shaft-driven by a 90hp Maximotor (later replaced by 300hp Hisso).
The stability of this design was proved in low-level test flights, and offered a 1:28 glide ratio and spin-proof characterictics. Twin tails, with elevators serving also as ailerons for banking. Although the War Department reportedly expressed interest, nothing came of the novel concept.

The War Dept assumed security and forbade any publicity.
