The Vortech G-1, also called the Compcop G-1, is an American helicopter that was designed in the 1970s. Plans for amateur construction were originally supplied by Compcop and today are provided by Vortech.[1][2][3] Design and developmentThe aircraft was designed long before the adoption of the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of {{convert|254|lb|kg|0|abbr=on}}, but nonetheless complies with them. The aircraft has a standard empty weight of {{convert|150|lb|kg|0|abbr=on}} and is billed as the "World's Tiniest Homebuilt Helicopter" by the plans supplier. It features a single main rotor and tail rotor, a single-seat open cockpit without a windshield, tricycle landing gear with main wheels and nose skid and a twin cylinder, air-cooled, two-stroke, single-ignition {{convert|40|hp|kW|0|abbr=on}} Rotax 447 aircraft engine or Kawasaki 440 snowmobile engine. The {{convert|50|hp|kW|0|abbr=on}} Rotax 503 can also be used.[1][2][3] The aircraft fuselage is made from bolted-together aluminum tubing. Its main rotor is {{convert|12|ft|m|1|abbr=on}} in diameter. Fuel capacity is {{convert|5|u.s.gal}}.[1][2] The plans supplier notes this warning: {{quotation|Vortech offers the G-1 plans as a curiosity for those interested in homebuilt helicopters because of its intriguing size and simplicity; however, Vortech has no direct experience with either the design or flight of this model and so cannot and does not endorse this as a proven aircraft. While people have reported building and flying this model, it appears that most of those flying versions were variations or enhancements of the original design.[2] }}Specifications (G-1){{Aircraft specs|ref=Cliche, Vortech and Kitplanes[1][2][3] |prime units?=imp
