The Aerosport OY Spider is a family of Estonian paramotors that was designed and produced by Aerosport OY of Keila 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 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. To make the various models different engine, reduction drive and propeller combinations are employed.^[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]
