British gyroplane

Merlin General information Type Autogyro National origin United Kingdom Manufacturer Layzell Gyroplanes Designer Jim Montgomery Status Production completed (2011)

The **Layzell Merlin** is a British [autogyro](/source/Autogyro) that was designed by Scottish designer Jim Montgomery and produced by [Layzell Gyroplanes](/source/Layzell_Gyroplanes) of [Quedgeley](/source/Quedgeley), [Gloucester](/source/Gloucester). The aircraft was supplied as a kit for [amateur construction](/source/Homebuilt_aircraft).[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](/source/Aircraft_fairing) and a windshield, [tricycle landing gear](/source/Tricycle_landing_gear) with [wheel pants](/source/Wheel_pants) and a twin cylinder, air-cooled, [two-stroke](/source/Two-stroke), single-ignition 64 hp (48 kW) [Rotax 582](/source/Rotax_582) engine in [pusher configuration](/source/Pusher_configuration).[1]

The aircraft [fuselage](/source/Fuselage) is made from bolted-together square [aluminum](/source/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](/source/Aircraft_registration) in the United Kingdom with the [CAA](/source/Civil_Aviation_Authority_(United_Kingdom)) as Montgomerie-Bensen B8MR.[3]
