The Warner Revolution I, also marketed as the Spacewalker I, is an American homebuilt aircraft that was designed and produced by Warner Aerocraft of Seminole, Florida.

When it was available the aircraft was supplied as a kit or in the form of plans for amateur construction.

[1] The aircraft is intended to be reminiscent of the open cockpit monoplanes of the 1930s, such as the Ryan ST.[1] The Revolution I features a cantilever low-wing, a single-seat, open cockpit with a windshield, fixed conventional landing gear with wheel pants and a single engine in tractor configuration.

The standard engine used is the 65 hp (48 kW) Continental A65 powerplant.
