The Hall Cherokee II is an American
Due to its low cost and ease of construction, the Cherokee II is one of the most produced home-built gliders.[2]
Design and development
The Cherokee was designed by Hall to provide homebuilders with an easy-to-construct and inexpensive aircraft that would give performance at least equal to the Schweizer SGS 1-26, which had flown two years earlier.[1][2]
The Cherokee structure is built from wood and covered in doped
As with all plans-built aircraft, builders have made modifications to the design. Some examples have been built with
Operational history
The first Cherokee II to fly was built by Frank Kerns and George McGinnis in 1956. The first flight was done by the designer, Stan Hall, in the late summer of 1956.[3]
Cherokee IIs have been used to earn many
Cherokee IIs have occasionally been flown in competition, usually in regional handicapped contests. The prototype Cherokee II was entered in the 1956 US National Championships at Grand Prairie, Texas, but was not allowed to compete as it had not flown the FAA-required 50 hours of flight test time within 25 miles (40 km) of its home airport.[3] In 1959, two Cherokee IIs competed at the Canadian national contest, with Ross Grady placing second and a team of Jim Reid and Ken Lewandowski coming in third.[7] In Class II of the 1960 US West Coast Championship, George Asdel and Stan Hall took first and second, respectively, in their Cherokee IIs.[8] Ray Proenneke flew in many US west coast meets and contests in the early 1960s and won the Torrey Pines meet in 1964.[9] Bud Brown flew several regional contests in the US midwest in the late 1960s, placing 7th, winning the handicap trophy, in the Wright Memorial Meet of 1967.[10] In the 1968 Region 6 Contest Bud flew to 11th overall, but once again won the handicap trophy.[11] In 1967, Peter Newgard flew his Cherokee to first place in the 25:1 glide ratio and under category at the US Region 11 contest.[10] Carl Herold won the 1976 US Region 11 Sports Class contest in a borrowed Cherokee II.[12] In the 1978 US Region 4 Sports Class contest, Ted Garnett came in first in his Cherokee II.[13] Dean Gradwell placed 5th in the US Region 11 Sports Class in 1983, winning one day's competition.[14] Tony Condon placed 3rd in the 2011 US Region 10 Soaring Championships flying his Cherokee II, winning two days.[15] In 2012, Condon flew his Cherokee to a 7th-place finish in the US 13.5 Meter Super Regionals.[16]
In March 2011 there were at least two Cherokee IIs in airworthy condition, one in the USA[17] and another in Australia.[18] The original Cherokee RM, built by Ree and Miller, had recently been flown after an extensive restoration.[19] At least three Cherokee IIs were currently undergoing restoration, two in the US and one in Australia.[20]
