Design and development

The series 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 or two-place-in-tandem accommodation and a single 28 hp (21 kW) Simonini Mini 2 Plus engine in pusher configuration with a 2.2:1 ratio reduction drive and a 110 to 130 cm (43 to 51 in) diameter two-bladed wooden propeller. The fuel tank capacity is 8 litres (1.8 imp gal; 2.1 US gal). The aircraft are 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]

gollark: Okay, not hax really, but still.
gollark: Or, well, I can, but it would require major redesigns and I don't know how exactly.
