The Fox was designed by Hans Gigax in Switzerland in 1982. Single-seat single-engined high-wing monoplane with conventional three-axis control. Wing has unswept leading edge, swept forward trailing edge and tapering chord; cruci-form tail. Pitch control by elevator on tail; yaw control by fin-mounted rudder; roll control by half-span ailerons; control inputs through stick for pitch/roll and pedals for yaw. Wing braced from above by kingpost and cables, from below by cables; wing profile double-surface. Undercarriage has three wheels in tricycle formation; suspension on all wheels. Push-right go-right nose-wheel steering connected to yaw control. Hand actuated brake on nosewheel. Aluminium-tube framework, with pod. Engine mounted at wing height driving tractor propeller.


The Fox single-seater made its first flight in December 1982 and underwent a programme of test flights with the intention of obtaining certification in West Germany. It was only a prototype. Rigging and derigging take 20 minutes and when folded it is transportable on a roof rack. The noise measured on the ground with the machine flying at 492ft (150m) with the motor at maximum power is 58dB; West German regulations stipulate 60 dB maximum.

Evektor-Aerotechnik also is marketing the braced high-wing two-seat Fox (a variant of the German Ikarusflug Eurofox, with Evektor of the Czech Republic having undertaken important design work, and Aeropro of Slovakia building airframes for Fox and Eurofox).

 

The single-seater Comco-Ikarus Fox D is a first generation micro-light aircraft. The single-seat Sherpa I was the first motorised Ikarus micro-light aircraft and entered serial production in 1982. In 1983, the single-seater Sherpa I was replaced in production by the Fox D, an open single-seater constructed out of aluminium tube covered with sailcloth. The nose of the plane is made out of glassfibre composite as used by the 2-seater Sherpa II. The prop of the Fox D is driven by a Göbler-Hirth F263 engine.
