 Originally the design was to be manufactured by a new company Aero-Max, which was a partnership between Schlitter and a friend of his.The partnership failed over financial issues and kit manufacturing was passed to Schlitter's company, Rans, which was at that time building sailtrikes.Both models of the family feature a welded 4130 steel tube cockpit, with a bolted aluminum tube rear fuselage, wing and tail surfaces all covered in pre-sewn Dacron envelopes, which shorten construction time.
