Airfer Bimax

The Bimax was designed as an aircraft for large pilots for two-place flying, 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 Cors'Air M21Y 23 hp (17 kW) engine in pusher configuration with a 2.6:1 ratio reduction drive and a 122 cm (48 in) diameter two-bladed composite propeller. The fuel tank capacity is 9 litres (2.0 imp gal; 2.4 US gal). The aircraft is built from a combination of aluminium tubing, with a titanium chassis.^[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]
