Design and development

The Spider line 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 engine in pusher configuration with a reduction drive. The fuel tank capacity is 10 litres (2.2 imp gal; 2.6 US gal). The basic design is built from aluminium tubing, plus a nylon harness. The various models employ different engine, reduction drive and propeller combinations.[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]
