The Hornet is a development of the Taggart GyroBee and was introduced in 1997. The Hornet was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 2540NaN0. The aircraft has a standard empty weight of 2540NaN0. It features a single main rotor, a single-seat, open cockpit without a windshield, tricycle landing gear and a twin cylinder, air-cooled, two-stroke, single-ignition 400NaN0 Rotax 447 engine in pusher configuration. The 500NaN0 Rotax 503 engine can also be fitted.
The aircraft fuselage is made from bolted-together aluminum tubing, while the landing gear and flight controls are fabricated from 4130 steel. The rotor has a diameter of 241NaN1, while the propeller recommended is a Powerfin composite model with a diameter of 60to. With an empty weight of 2540NaN0 and a gross weight of 5340NaN0 the design offers a useful load of 2800NaN0. Without a pre-rotator fitted the Hornet requires 600to to become airborne.[2]
