Ultralite Soaring Wizard

Design and development

Developed from the Eipper Quicksilver E, the Wizard was designed before the introduction of the US FAR 103 Ultralight Vehicles rules, but complies with them, including the category's maximum empty weight of 254 lb (115 kg). The W1 model has a standard empty weight of 167 lb (76 kg). It features a cable-braced high-wing, a single-seat, open cockpit, tricycle landing gear and a single engine in pusher configuration. It differs from the Quicksilver primarily in the configuration of the tail boom tubes and the use of drooped wing tips.

The Wizard is made from bolted-together aluminum tubing, with its flying surfaces covered in Dacron sailcloth. Its single-surface 32.3 ft (9.8 m) span wing has its cabling supported by a single tube style kingpost. The landing gear uses tube flexing for suspension and features a fixed nose wheel. On the early models the pilot is accommodated on a sling seat suspended from the main wing keel tube, to allow weight-shift control. The standard engine supplied was the single cylinder, two-stroke Yamaha KT-100S of 15 hp (11 kW), although a Kawasaki 440 snowmobile engine producing 38 hp (28 kW) was optional.

The Wizard was commercially successful and a large number were completed and flown. Construction time from the supplied assembly kit is about 100 hours.
