Abstract: A remotely powered and controlled aircraft is provided of the type wherein the propeller is driven from a remote drive unit by an elongated flexible cable confined within a flexible tube. The aircraft of the invention includes a secondary control knob slidably and rotatably mounted about the flexible tube for selectively controlling the effective length of the tube and cable to thereby control the radius of flight of the aircraft. In a preferred embodiment, the aircraft is a biplane with a unique wing support construction, including eyelets in the wings and flexible struts having wing engaging hooks thereon which may be selectively inserted through the eyelets for engagement with the wings. This abstract is not to be construed in any way to define or limit the invention set forth below.
