The Revolution Mini-500 is a 1990s American single-seat light helicopter, designed and built by Revolution Helicopter Corporation as a kit for homebuilding.
The Mini-500 was designed as a light helicopter that resembles a scaled-down Hughes 500, powered by a Rotax 582 64 hp (48 kW) two-stroke engine.
The Mini-500 has a tubular steel fuselage with a foam and glass-fibre structure cabin. It has a two-bladed semi-rigid rotor and a conventional two-blade tail rotor.
The Mini-500 design was initially based upon Augusto Cicaré’s control system design as incorporated in his CH-6 prototype helicopter, but Fetters and Cicaré were unable to agree on licensing terms. Revolution Helicopter went out of business in November 1999 and kits are no longer available.
