The S-7 was originally conceived of as a trainer for the single seat S-4 Coyote. First flown in November 1985 the Courier was named for an aircraft that Schlitter admired, the Helio Courier.[3][4][6][8][10]
The S-7 features a welded 4130 steel tube cockpit, with a bolted aluminum tube rear fuselage, wing and tail surfaces all covered in dope and fabric. The reported construction times for the Courier are 500-700 man-hours.[1][2][4]
The Courier is available only with conventional landing gear but can 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 100 hp (75 kW) Rotax 912ULS.[1][2][3][4] At least one S7 has been fitted with a Jabiru 2200 flat-four, four-stroke direct-drive engine.[11]
Operational history
325 examples of the Courier had been completed by December 2007.[2] In November 2010 74 were on the registers of European countries west of Russia.[12]
Reviewer Marino Boric said in a 2015 review, that, "this refined little fun flyer...continues to prove itself deservedly popular."[13]
In an extensive review in December 2020, AVweb writer Dave Prizio praised the design's ergonomics and economics, "a nice feature of the S-7 is its ample 30-inch-wide cabin. Even for large people, there is no need to squeeze into an S-7 the way you might into a Cub. It will pretty much do the same thing as a Super Cub at a lower operating cost."[14]
