McCulloch J-2

[1] The design featured a belt clutch and a transmission which could be engaged to spin the rotor blades to high speed before take-off to produce short takeoff runs.

A later "Super J-2" variant employed a three-bladed Hartzell controllable-pitch propeller, accompanied by an increase in allowable gross weight.

At a typical fuel burn rate of about eight gallons per hour and economy cruise at about 85 mph, with a need for a safety reserve, this limited the aircraft's range.

[citation needed] The rotor system (hub and blades) is very similar to that found on the early versions of the Hughes 269 / Schweizer 300 series helicopters.

[2] In 1974, the rights were bought by Aero Resources, who planned to return the Super J-2 to production, but could not find a market for the aircraft and no more were built.

McCulloch J-2 registered in the United Kingdom between 1972 and 1975
