Sonex Aircraft, LLC is an American kit aircraft manufacturer located in Oshkosh, Wisconsin, producing kits for four all-metal homebuilt monoplanes. The company was founded in 1998 by John Monnett, who has designed the Monnett Sonerai sport aircraft series, Monnett Monerai sailplane, Monnett Moni motorglider, and Monnett Monex racer.
History
The company opened a flight center and a 5,600 sq ft (520 m2) parts distribution warehouse in 2006.[1]
In 2013, the FAA National Kit Evaluation Team (NKET) approved fast-build "51% rule" versions of the Sonex, Waiex, and Onex.[2]
Jeremy Monnett, the son of founder John Monnett Jr. and CEO, was killed in an airplane crash in 2015.[3]
In June 2018, John Monnett announced his plan to retire and sell the company.[4] In January 2022, Sonex employee and general manager, Mark Schaible, purchased the assets of Sonex Aircraft LLC and Sonex Aerospace LLC, forming them into a new company, Sonex LLC. Schaible will be owner and president of the new company.[5]
In December 2019 the John Monnett-designed Sonerai was acquired by Sonex Aircraft.[6]
The company rolled out a prototype highwing aircraft in 2024.[7]

E-flight
At AirVenture 2007, Sonex Aircraft announced a project to work on innovative technologies in aviation. The E-flight projects includes using an electric motor, ethanol-based fuels, and other power plant alternatives.[16] In December 2010, an all-electric Waiex was test flown from Wittman field in Oshkosh, Wisconsin. The aircraft was flown with a 54 kW (72 hp) brushless DC electric motor, managed by a newly designed controller. Power is from a collection of 14.5 kW-hour lithium polymer batteries, giving the aircraft an endurance of one hour at low-speed cruise or 15 minutes of aerobatics.[17][18] This was the beginning of the development of the Sonex Electric Sport Aircraft.[19]
