The Rans S-6 Coyote II is an American single-engined, tractor configuration, two-seat, high-wing monoplane designed by Randy Schlitter and manufactured by Rans Inc. The Coyote is available in kit form for amateur construction or as a completed light-sport aircraft.[1][2][3][4][5][6][7][8]

Design and development

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 II kit can be ordered with tricycle or conventional landing gear, and can also be equipped with floats and skis. The original basic engine was the Rotax 503 of 50 hp (37 kW), with the Rotax 582 of 64 hp (48 kW) being available as an option. Today, the standard engine is the 80 hp (60 kW) Rotax 912UL, with the 100 hp (75 kW) Rotax 912ULS being optional.[1][2][3][4][5][6] The aircraft can also be fitted with the Sauer S 2200 UL[10]

Operational history

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]
