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).
Single-seat single-engined flex-wing aircraft with weight-shift control. Cage containing landing gear/engine unit is suspended from CG position by strong universal-type joint for easy conversion from hang glider to powered glider. Rogallo wing with keel pocket. Pilot suspended below wing in trike unit, using bar to control pitch and yaw/roll by altering relative positions of trike unit and wing. Wing braced from above by kingpost and cables, from below by cables; cross-tube construction with double -surface enclosing cross-tube. Undercarriage has three wheels in tricycle formation. Bungee-cord suspension and push-right go-left nosewheel steering independent from yaw control. Aluminium-tube trike unit, without pod. Engine mounted below wing driving pusher propeller. 6061T6 aluminium tubing, anodized. Stainless-steel vinyl-coated rigging.
