The aircraft was supplied as a kit for [[Homebuilt aircraft|amateur construction]].<ref name="WDLA11">Bayerl, Robby; Martin Berkemeier; et al: ''World Directory of Leisure Aviation 2011-12'', page 182.

The type remained in production by Layzell through 2011, although by July 2012 the company website had been removed from the internet.<ref name="WDLA11" /><ref name="Layzell">{{cite web|url=http://www.gyrokits.com/ |title=Gyro Kits |accessdate=5 January 2013 |last=Layzell Gyroplanes |date=n.d. |url-status=dead |archiveurl=https://web.archive.org/web/20111117042115/http://www.gyrokits.com/ |archivedate=17 November 2011 }}</ref>

==Design and development== The Merlin features a single main rotor, a single-seat open cockpit with a [[Aircraft fairing|fairing]] and a windshield, [[tricycle landing gear]] with [[wheel pants]] and a twin cylinder, air-cooled, [[two-stroke]], single-ignition {{convert|64|hp|kW|0|abbr=on}} [[Rotax 582]] engine in [[pusher configuration]].<ref name="WDLA11" />

The aircraft [[fuselage]] is made from bolted-together square [[aluminum]] tubing. Its {{convert|7.01|m|ft|1|abbr=on}} diameter Rotor Flight Dynamics rotor has a chord of {{convert|18|cm|in|1|abbr=on}}. The aircraft has an empty weight of {{convert|145|kg|lb|0|abbr=on}} and a gross weight of {{convert|295|kg|lb|0|abbr=on}}, giving a useful load of {{convert|150|kg|lb|0|abbr=on}}.<ref name="WDLA11" />

After taking over Montgomery's design, company owner Gary Layzell expressed an interest in further developing the Merlin, but initially produced it unchanged.<ref name="WDLA11" />

==Operational history== By January 2013, 28 examples had been [[Aircraft registration|registered]] in the United Kingdom with the [[Civil Aviation Authority (United Kingdom)|CAA]] as Montgomerie-Bensen B8MR.<ref name="GINFO">{{cite web|url = http://www.caa.co.uk/application.aspx?catid=60&pagetype=65&appid=1&mode=summary&aircrafttype=MONTGOMERIE-BENSEN%20B8MR|title = GINFO Search Results Summary|accessdate = 5 January 2013|last = [[Civil Aviation Authority (United Kingdom)]]|date = 5 January 2013}}{{Dead link|date=August 2025 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> <!-- ==Variants== --> <!-- ==Aircraft on display== -->
