Kellett XR-8 (Restoration Update Jan 17, 2024)

Developed as a prototype for the USAAF in 1940s, the Kellett XR-8 tested the idea of stabilizing a helicopter by using dual offset horizontal rotors to eliminate the need to power a tail rotor. Nicknamed “Eggbeater,” the design used two intermeshing wooden propellers above the two person cabin. The XR-8 first flew on August 7, 1944.
Though the XR-8 was a revolutionary design, the Kellett Aircraft Corporation
encountered significant problems with stability control and timing the rotors.
The company modified the vertical stabilizers in an attempt to resolve some of these issues. Because of these and other complications, Kellett only produced two XR-8s before cancelling the program. The artifact on display is the only surviving version of the XR-8.
Technical Notes
Engine: Horizontally opposed Franklin six-cylinder engine of 245 hp
Maximum Speed: Approximately 100 mph
Ceiling: Approximately 10,000 ft

Looking at this, I wonder seeing that beauty in its real look. It will look awesome once you guys restore another great aircraft.

Wow, the lone R-8. Like a lot of the planes in the Museum, would love to see them fly again, (especially the ones I worked on!), even though this one had those pesky syncrotor issues!

Im glad it’s getting restored and was saved from the NASM storage facility

Does anyone know when they are moving the Boeing X-32A to hangar four?
