Flexible wings hinged at the fuselage allowed the pilot to vary dihedral and angle of attack for controlled performances. Struts contained shock absorbers with air pressure supplied by compressed air tanks fed by the motor. Also had a 6' central skid acting as an arresting gear after landing.
Only the one was built, becoming the W-1.
The 1931 W-1 (NC169W) and W-1 Special (NC172M) (ATC 2-325) was a continuation of the Flex-Wing experiments; nicknamed "Rubber Duck." The W-1s feaured ddjustable-incidence and -dihedral wings with shock-absorbing struts.Lack of funding canceled the project after the two.
