Replica and reproduction Gee Bee aircraft[edit]

Airworthy Gee Bee R-2 Super Sportster replica at Fantasy of Flight

A Model E replica was flown and wrecked before being donated to the Evergreen Aviation & Space Museum in McMinnville, Oregon. Another Model E replica was being built in Australia.[10]

A replica of Florence Klingensmith's Model YL was completed in 1984 powered by a 300 hp (220 kW) Lycoming R-680.

A Model Z replica first flown in 1978 was used by the Walt Disney Company in the film The Rocketeer (1991), which is now on display at the Seattle Museum of Flight. A second Gee Bee Z replica was sold to Fantasy of Flight.

The New England Air Museum and the San Diego Air & Space Museum have each completed replica R-1s with help from the Granville's under the agreement that the aircraft will never be flown. The Crawford Auto-Aviation Museum in Cleveland, Ohio also has an R-1 replica on display as of June 2018. The Springfield, Massachusetts Museum of Springfield History has a full size static fiberglass replica of the R-1 hanging in the atrium.[11] A Gee Bee R-2 Super Sportster replica flown extensively since 1991 is now at Fantasy of Flight.

A highly modified replica of the Gee Bee R-6 powered by a 1,425 hp (1,063 kW) Wright R-1820 Cyclone was first flown on 26 September 2013.
