In addition to the stressed-skin construction, Reggiane introduced several advanced features on the Re.2000, such as a modern structure, which was considerably more advanced than the ones used in Macchi's and other Italian fighters of the time, along with an elliptical wing profile. Overall, the design possessed greater aerodynamic sophistication in comparison to other Italian rivals such as the Fiat G.50 and Macchi C.200. The Re.2000 was furnished with retractable landing gear; the main gear retracted via the Curtiss method, the wheels rotating around to face flat within the wheel wells when retracted. The atypical fairing covered the landing gear's actuation mechanism, while the legs incorporated hydraulic shock absorbers and drag struts to effectively absorb loads; pneumatic brakes were also fitted. The tail wheel was both retractable and steerable.
