The Hughes/Schweizer 300 is the best three seat helicopter assembled, with in excess of 3400 created by the two makers in excess of three decades
Improvement of this adaptable utility helicopter goes once again to the mid 1950s when Hughes flew the two seat Model 269 without precedent for October 1956. The fundamental outline started US Army investment and it requested five as the Yho2hu for assessment in the scout and perception parts. Conveyances of the business comparable Model 269a started in 1961.
The 269a project got a tremendous help when Hughes won a US Army contract for a light helicopter essential mentor. In every one of the 792 were manufactured as the Th55a Osage and more than 60,000 US Army helicopter pilots learnt to fly in the sort.
Hughes took after the two seat 269a with the somewhat bigger three seat 269b, which it advertised as the Hughes 300, which first flew in 1964. The 300 was emulated from 1969 by the enhanced 300c, which presented an all the more effective 140kw (190hp) Lycoming Hio360 motor and expanded distance across principle rotor, giving an expand in payload of 45%, or more execution changes. The 300c (or 269c) flew in August 1969 and stays in creation fundamentally unaltered.
Since 1983 the 300c has been fabricated by Schweizer in the USA. Schweizer constructed the 300c at first under permit for Hughes, and afterward procured all rights to the helicopter in 1986. Under Schweizer's stewardship more than 250 minor upgrades have been made to the 300c, yet the fundamental configuration has been left unaltered. Schweizer likewise offers a rendition upgraded for police work. Named the Sky Knight it is accessible with alternatives, for example, a hunt light and infrared sensors.
The most recent 300 model is the 300cb coach controlled by a Ho360c1a and conveyed from late 1995.
