Advanced Aviation Hi Nuski Advanced Aviation Hi-Nuski-Huski Advanced Aviation Coyote  Huski
The Hi-Nuski was a three axis (actuated by weight shift) ultralight, a clone of the Eipper Quicksilver. The changes were a 2 in. square wing-root tube, more forward engine placement, re-engineered prop drive shaft, harness actuated ailerons, open wing tips, larger rudder and tricycle undercarriage. First built in 1978, this appeared at Oshkosh 1979 and by June 1981, 147 had been delivered. The Hi-Nuski, was fitted with a twin Chrysler engine pack and trim elevators, and created the Hi-Nuski-Huski. A monowing with conventional tail, control is accomplished by weight shift, with rudder and ailerons attached to a movable harness. The separate rudder is all-flying. Pitch is controlled by variable CG. Construction consists of aluminum tubing covered with 3.9-ounce Dacron on the wing and tail surfaces. The fuselage uses square tube. The engine was one Cuyuna mounted in pusher position at the center of the wing. Direct drive turns a two-blade Woods wooden propeller. Fuel is carried in a nylon rotocast tank, which is attached by one bolt through the center and cushioned on a foam pad. The landing gear was coil-spring tricycle gear with a steerable nosewheel and no brakes. All wheels were 10-inch. The Huski in its various forms (it was originally called Hi-Nuski, then after some improvements the Hi-Nuski Huski, and finally just Huski), was produced for several years and was complemented by the Huski II. The Huski is a single-seat single-engined high-wing monoplane with hybrid control. Wing has unswept leading and trailing edges, and constant chord; cruciform tail. Pitch control by fully flying tail; yaw control by fully flying rudder; roll control by one-third-span spoilers; control inputs through weightshift for pitch/yaw/roll. The single-surface wing is braced from above by kingpost and cables, and from below by cables. Undercarriage has three wheels in tricycle formation; steel-spring suspension. Nosewheel steering is independent from yaw control. No brakes. Of aluminium tube framework, without pod. Engine mounted above wing driving pusher propeller. Tubing used is 6061T6 aluminium; wing covering is Dacron. The Cuyuna engine is mounted above the wing and drives a twin bladed propeller in line with the trailing edge of the wing, between the two tubes which are angled back to support the tailplane. The Huski is a hybrid, in that although its control inputs are solely weightshift, the change in direction or attitude caused by this alteration of centre of gravity is assisted by one or more control surfaces, in this case elevator, rudder and spoilers. The Huski II has a similar motor, but whereas the Huski made use of the Cuyuna 430D twin-cylinder in-line engine producing 30 hp and with direct drive, the Huski II used the 430RR Cuyuna of the same capacity but with a reduction drive of 2/1 to improve fuel efficiency, power and noise level, and twin ignition. Apart from this engine difference, the aircraft are basically the same and used 6061T6 aluminium alloy tube and Dacron fabric with rigging by stainless steel wires. The Huski II was offered with optional floats, nosewheel brake, instrument panel and parachute. Both the Huski and Huski II were discontinued by 1982, the company having decided to concentrate production on the three-axis Cobra. Another option, introduced in 1982, was the Coyote, a smaller engined version of the Huski. The Coyote used the single-cylinder Cuyuna of 215 cc with a reduction drive, and had an optional float kit. The model was discontinued early in 1983.
