Delta Wing Kites Trike
Delta Wing Kites turned to the produc-tion of trikes intended for mounting under a standard hang-glider wing without any mod-ification to the latter in 1979. The first trikes sold by DWK were similar in every way to European models, using at first the Soarmaster trike unit with the single Chrysler 820 engine developing 10hp at 8000 rpm. In 1980 they offered an option of twin Chryslers or the German Solo 335 engine of 210 cc, which develops 20 hp at 7000 rpm. To accompany the trike unit, DWK offered initially its Phoenix D wing in various sizes, but this was replaced by the Phoenix X series; the trike unit can be used equally well under any other manufacturer's Rogallo.
Because of the American legislation, the company only builds single-seaters.
The company has also built trikes with Yahama KT-100S and Lloyd engines, but standardised on Robin power. Principal trike units offered in 1982 were with Robin EC25PS (22 hp, recoil start, $2250), EC34PM (32 hp, recoil start for $2395 or electric start for $2570), EC34PL (55.5 hp, recoil start $2795), and EC44PM (50hp, electric start, $2670).
