The Layzell Merlin is a British autogyro that was designed by Scottish designer Jim Montgomery and produced by Layzell Gyroplanes of Quedgeley, Gloucester. The aircraft was supplied as a kit for amateur construction.^[1]

The type remained in production by Layzell through 2011, although by July 2012 the company website had been removed from the internet.^[1]^[2]

Design and development

The Merlin features a single main rotor, a single-seat open cockpit with a fairing and a windshield, tricycle landing gear with wheel pants and a twin cylinder, air-cooled, two-stroke, single-ignition 64 hp (48 kW) Rotax 582 engine in pusher configuration.^[1]

The aircraft fuselage is made from bolted-together square aluminum tubing. Its 7.01 m (23.0 ft) diameter Rotor Flight Dynamics rotor has a chord of 18 cm (7.1 in). The aircraft has an empty weight of 145 kg (320 lb) and a gross weight of 295 kg (650 lb), giving a useful load of 150 kg (331 lb).^[1]

After taking over Montgomery's design, company owner Gary Layzell expressed an interest in further developing the Merlin, but initially produced it unchanged.^[1]

Operational history

By January 2013, 28 examples had been registered in the United Kingdom with the CAA as Montgomerie-Bensen B8MR.^[3]
