The company specialized in the design and manufacture of autogyro parts and at one time produced whole aircraft kits for amateur construction in the US including FAR 103 Ultralight Vehicles category.
[1][2] The company was formed in the 1970s as Calumet Aeronautics, nicknamed Cal Aero and acted as a dealer for "Airguide" wind meters.
The Calumet designed Explorer Ultralight gyroplane was first flown in May 1997 and produced through the late 1990s and early 2000s when it was noted as a low-cost, entry level aircraft.
[1][2] The aircraft was commercially successful, but required additional investment to expand production and instead the line was sold.
When the SnoBird line came up for sale again later, Calumet Motorsports bought the seat fuel tank business.
