Freewind Bumble B

The Freewind Bumble B is a French autogyro that was designed  and produced by Freewind Aviation of Vimory, introduced in about 2013. Now out of production, when it was available the aircraft was supplied complete and ready-to-fly.

Freewind Aviation seems to have been founded about 2013 and gone out of business in 2014. It is not clear how many aircraft were produced, although at least one example flew.

Design and development
The Bumble B features a single main rotor, a two-seats-in tandem open cockpit with composite fairing and a windshield, tricycle landing gear and a modified four-cylinder, liquid and air-cooled, four stroke, turbocharged 122 hp Rotax 912 engine in pusher configuration.

The aircraft has a two-bladed rotor with a diameter of 8.4 m and a chord of 21.5 cm. The aircraft has a typical empty weight of 258 kg and a gross weight of 450 kg, giving a useful load of 192 kg. With full fuel of 75 L the payload for the pilot, passenger and baggage is 138 kg.

Reviewer Werner Pfaendler described the design as, "a low cost but good quality gyrocopter with excellent flight characteristics".
