The United Consultants Twin Bee is an American twin-engined light amphibious aircraft of the 1960s.

In 1960, former Helio company engineer Joseph W. Gigante (1916-2012) designed a twin-engine conversion of the Sea Bee and founded United Consultants Corp in Norwood, Massachusetts, to undertake the manufacturing work on the UC-1 Twin Bee.

The single pusher engine is deleted and this allows an additional fifth seat to be fitted beneath the old installation.

The twin 180 hp (134 kW) Lycoming engines, mounted in tractor configuration, are fitted in the wing, fairly close to the cabin.
