Calumet Snobird Explorer

The Calumet Snobird Explorer was an American autogyro designed and produced by Calumet Motorsports of Lansing, Illinois, introduced in May 1997. Now out of production, when it was available, the aircraft was supplied as a kit for amateur construction.

Design and development
Calumet Aeronautics, owned and operated by Tommy Milton, designed an entry level Ultralight gyroplane. Calumet Aeronautics then purchased the assets of the SnoBird Aircraft Company. After moving the assets from Bristol, TN. to Lansing, IL. Tommy Milton and partner, George Smundin inventoried the SnoBird assets and decided to put the entire Snobird line back in production after evaluating the design integrity and high quality of the manuals. Tommy and George decided to put the Snobird line back into production. The company name was changed to Calumet Motorsports due to the difficulty of purchasing bearings and other critical components. The gyroplane business grew and an additional partner was taken on who, eventually bought out Tommy and George. The new owner later sold the business. The new owner sold parts of the business back to Calumet Motorsports. The new owner resold the business once again and the design remains out of production.

The Snobird Explorer was designed as a low-cost, entry-level autogyro, to comply with the US FAR 103 Ultralight Vehicles, including the category's maximum empty weight of 254 lb. The aircraft has a standard empty weight of 244 lb. It features a single main rotor, a single-seat open cockpit, tricycle landing gear and a twin-cylinder, air-cooled, two-stroke, single-ignition 40 hp Rotax 447 engine in pusher configuration.

The aircraft fuselage is made from a combination of composite material and aluminum and features a tall tail design to reduce engine-induced yaw. The kit was supplied with jig pre-drilled holes and was powder coated. Its two-bladed rotor has a diameter of 23.0 ft. Full fuel is 5 u.s.gal.
