The original single seat S-4 Coyote was designed by Rans owner Randy Schlitter in 1982, as a result of his dissatisfaction with existing ultralight designs at the time. Construction of the first Coyote prototype was started in November 1982, with the first flight following in March 1983.[9]
The Coyote II two-seater was developed from the S-5 Coyote, itself a development of the S-4 Coyote. The initial two seat model, the S-6, was replaced by the improved S-6ES ("extended span") model in April 1990. In 1993, the ES was joined in production by the S-6S Super Coyote.[1][4][5][6]
All models of the S-6 feature a welded 4130 steel tube cockpit, with a bolted aluminum tube rear fuselage, wing and tail surfaces all covered in fabric. In the initial S-6 and S-6ES, the fabric consists of pre-sewn Dacron envelopes, which shorten construction time. The S-6S, however, uses the more traditional dope and fabric. The reported construction times for the ES are 250 man-hours versus 500 for the Super.[1][2][3][4][5][6]
The Coyote has proven to be popular with customers, with over 1800 examples of the type having flown as of January 2008.[4][5][7] In November 2010 615 were on the registers of European countries west of Russia, excluding Ireland.[11][12]
One example of the S-6ES was flown across the Atlantic Ocean twice.[2]
