The Spectrum helicopters were designed primarily for high-speed transportation of personnel over short distances, particularly where rough and difficult terrain is involved, and for reconnaissance duties. Based on the World Army Air-force "Rotar" (Round Tail Rotor) heli-jets (2066), the Spectrum helicopters are usually armed with a single machine-gun, and are powered by seven air-feed mark II Windenown turbo-engines. The triple rotor-blades (for lift, travelling at 2,000 RPM), plus quad bladed ring-rotor for tail, are driving by two of these air-inducted turbo-jets. The helicopters are 45 feet long with 19 feet 6 inches wide each rotor-blade, giving a rotor-diameters of 39 feet), a weight of 36,000 Lbs (16.07 Tons). They have a flight ceiling of 40,000 feet (height of Cloudbase) and a top speed of 302 MPH. The spectrum helicopters are five seater vehicles, constructed at Universal Engineering Incorporated, Sydney, Australia. The helicopters are powered by fuel distilled from the Spectrum refinery at Bensheba, are made from Fleetonium allow and are Blue and White in colour. The landing legs are fitted with black floatation pods/pontoons for landing on water.
