Guee

   In Nice in 1908 a man named Guee tested a monoplane model under Ferber's "aerodrome" pylon; by early 1909 he had built a biplane glider which was intended to be powered. It was a simple equal-span biplane with rectangular wings and a tail on a single outrigger. Between the wingtips were ailerons, each with small triangular vertical surfaces both above and below, apparently to act as rudders, turning while the ailerons moved up and down.
