The aircraft are available in kit form for amateur construction. Production of the S-12S Airaile, S-14 Airaile, S-17 Stinger and S-18 Stinger II was ended as part of Rans' extensive reorganization of its product line on 1 June 2006. The S-12XL Airaile was originally intended to be cut from the line at the same time, but customer demand convinced the company to retain the model and it is still available in 2015 as a special order The S-12 Airaile was designed by Randy Schlitter and introduced in March 1990 as a two-seat side-by-side, tricycle gear ultralight aircraft for recreational and flight training use. The single-seat version of the S-12, the S-14 Airaile, was designed one year later and entered production in 1991. The S-17 Stinger retains the wings, tail, boom tube of the S-14, mated to new forward 4130 steel tube cockpit and equipped with conventional landing gear to create an open-cockpit ultralight that complies with the US FAR 103 Ultralight Vehicles regulations. The S-18 Stinger II uses the S-12's wings, tail and boom tube, again with a new forward steel tube fuselage to create a tandem seat, conventional landing gear, open cockpit ultralight trainer.
