The Walkerjet Spider is a Czech paramotor that was designed by Victor Procházka and produced by Walkerjet of Třemošná for powered paragliding. Now out of production, when it was available the aircraft was supplied complete and ready-to-fly.[1]

Design and development

The Spider was designed to comply with the US FAR 103 Ultralight Vehicles rules as well as European regulations. It features a paraglider-style wing, single-place accommodation and a single 14 hp (10 kW) Radne Raket 120 engine in pusher configuration with a 3:1 ratio reduction drive and a 130 cm (51 in) diameter two-bladed wooden propeller. The fuel tank capacity is 8 litres (1.8 imp gal; 2.1 US gal). The aircraft is built from a combination of bolted aluminium and 4130 steel tubing. The propeller cage can be dismantled for ground transport or storage.[1]

As is the case with all paramotors, take-off and landing is accomplished by foot. Inflight steering is accomplished via handles that actuate the canopy brakes, creating roll and yaw.[1]
