The Willy 100 is a side by side high wing design with welded steel spaceframe fuselage, spars in dural and wooden ribs.

The Wizard W-1 was a single seat single engined high wing mono¬plane with weight shift control. Wing has unswept leading and trailing edges, and constant chord; cruciform tail. Control inputs through weight shift for pitch/yaw/roll. Wing braced from above by kingpost and cables, from below by cables; wing profile; largely single surface. Undercarriage has three wheels in tricycle formation with additional tailskid; torsion bar suspension on all wheels. No ground steering (optional: Steerable nosewheel independent from yaw control). Optional brakes. Aluminium tube framework, without pod. Engine mounted below wing (above wing, optional) driving pusher propeller.

Ultralight Soaring Wizard Article

The basic Wizard W-1 uses purely weightshift control without control surfaces and has a very similar configuration to the early Quicksilvers, though it differs greatly in terms of structure, not least because it was designed from the outset to be an ultralight. Adjustable torsion bar suspension is standard on the W 1; options include floats, steerable nosewheel (the standard nosewheel castors), brakes, and an engine mounting above the wing for certain power packs. It is sold as a kit requiring 45 min assembly and in March 1983 cost $1800 in standard form without engine. The June 1983 price for a complete aircraft with Yamaha engine is $3495. Power packs may be purchased separately at the following prices (all March 1983): Yamaha KT100S $1500, Rotax 277 $1800, Rotax 377 (34 hp) $2050, Rotax 503 (46 hp) $2225, Kawasaki TA440A $2225. Units delivered by June 1981 650.

The Wizard J 2 is identical to the W 1 except that it has control surfaces in two axes to assist the pilot’s weight shift. Linked to the pilot’s swing scat are spoilers for roll control and a trim tab (it is really too small to be called an elevator) for pitch. There is no rudder. Price (March 1983) without engine is $1900. The June 1983 price for a J 2 with Rotax 277 engine is $3895.

The Wizard J 3 was a single seat single engined high wing mono¬plane with conventional three axis 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 with additional fin; roll control by spoilerons (Wizard J 3), ailerons (Wizard J 3 Magnum); control inputs through stick for pitch/roll and pedals for yaw. Wing braced from above by kingpost and cables, from below by cables; wing profile; largely single surface. Undercarriage has three wheels in tricycle formation; with additional tailskid; torsion bar suspension on all wheels. No ground steering (optional: push right go right nosewheel steering connected to yaw control). Brake on nosewheel (optional brakes on main wheels). Aluminium tube framework, with optional pod. Engine mounted below wing (above wing, optional) driving pusher propeller.

Though very similar in concept to the W 1 and J 2, the Wizard J 3 has a number of changes compared to these models. Being a conventional three axis model, the pilot’s seat is fixed and a normal centre stick and rudder pedals are fitted. Also, the tail is redesigned making the J 3 easily recognisable by the inverted L shape of its vertical tail surfaces.

The J 3 comes as standard with a nosewheel brake, main wheel brakes being optional. Also optional is the J 3 Magnum specification, which involves replacing the spoilerons with ailerons. Other options are as for the W 1.
Price of the J 3 in kit form requiring 25 h assembly is $2500 without engine (March 1983). The June 1983 price for the J 3 with Kawasaki engine is $4720.

The Wizard Sky Tractor is a crop spraying version of the Wizard J 3. Revealed at Sun ‘n’ Fun in March 1983, the Sky-Tractor is still an ultralight thanks to an empty weight of 222 lb (101 kg) without its special equipment, which means that it can still be flown without a pilot’s licence in the USA. It can be fitted with crop spraying equipment using two atomisers under each wing, but both its specification and its price depend upon the requirements of the client. It is fitted in standard form with the Rotax 503 engine of 46 hp.

The Wizard T 38 was a side by side two seat single engined high wing monoplane with conventional three axis control. Wing has unswept leading and trailing edges, and constant chord; cruciform tail. Pitch control by elevator on tail; yaw control by fully flying rudder with additional fin; roll control by one third span spoilers; control inputs through stick for pitch/roll and pedals for yaw. Wing braced from above by kingpost and cables, from below by cables; wing profile NC; largely single surface. Undercarriage has three wheels in tricycle formation with additional tailskid; torsion bar suspension on all wheels. Push right go right nosewheel steering connected to yaw control. Aluminium tube framework, without pod. Engine mounted below wing driving pusher propeller.

The prototype of the two seat Wizard made its first flights at the end of 1982 and since January ’83 has been sold under the name of T 38. Being a two seater, this aircraft is classed as an experimental aircraft in the USA. The T 38 is sold as a kit requiring 1 h 30 min for assembly and is available in two versions with two separate seats and dual controls for $4800 or with single controls and a bench seat for $4600. The price does not include the engine unit, which for this model is the Rotax 503.

Designed by John Dempsey, the Phantom is a single seat single engined high wing monoplane with conventional three axis control. Wing has unswept leading and trailing edges, and constant chord; cruciform tail. Pitch control by elevator on tail; yaw control by fin mounted rudder; roll control by full span ailerons; control inputs through stick for pitch/roll and pedals for yaw. Wing braced from above by kingpost and cables, from below by cables; wing profile; double surface. Undercarriage has three wheels in tricycle formation with tailskid; bungee suspension on all wheels. Push right go right nosewheel steering connected to yaw control. Optional brakes on main wheels. Aluminium tube framework, with pod. Engine mounted above wing driving tractor propeller.

Conceived under the direction of John Dempsey, the Phantom copied in 1982 the exploits of the Mirage in the previous year at Sun ‘n’ Fun where it carried off the prize for the most outstanding aircraft.

The Phantom is capable of a rate of roll, going from 45 degrees bank to 45 degrees bank the other way in 1.5 s. The wing has been tested as far as + 9.9 and 6.6 g ultimate with the aircraft at a gross of 420 lb (190kg) which would give a flight envelope of +6.6 and 4.4g. These tests were done with 3/32 inch (2.4 mm) cables which on the production aircraft have been increased to 1/8 inch (3.2 mm).

Ultralight Flight Phantom Article

The aircraft is delivered as a kit requiring 35 h for finishing at a price of $5995 in 1983. Options include principally, floats, wheel fairings, an instrument panel and, as with the Mirage MkII, the Cuyuna 430RL engine, since the Phantom is fitted with the Kawasaki TA440A as standard in the United States.

For Europe, the Skyriders company in Britain fits a Robin engine and a larger fuel tank and, since the aircraft thus modified has different performance characteristics etc.

Later marketed as the Phantom Sport Airplane Corp Phantom X1 and X2. The X2 being a two seat adaptation of the X1.

In 1983 ULAC is working on a MX PUL 425 engined single seater of the X-99, called the X 77, but no other details were available.

Tandem two seat single engined high wing monoplane with conventional three axis con¬trol. Wing has unswept leading and trailing edges, and constant chord; V tail. Pitch/yaw control by elevon; roll control by one third-span spoilers; control inputs through stick for pitch/roll and pedals for yaw. Wing braced from above by kingpost and cables, from below by cables; wing profile 100% double surface. Undercarriage has three wheels in tail dragger formation; steel spring suspension on tailwheel and suspension on main wheels. Push right go right tailwheel steering connected to yaw control. Brakes on main wheels. Aluminium tube framework, with optional pod. Engine mounted below wing driving pusher propeller.

Georges Borgeaud, the president of ULAC, acquired on the 14 August 1981 the rights to sell in Europe and Africa the Maxair Hummer. Starting with the basic single seater model designed by the late Klaus Hill, ULAC has developed its own tandem two seater, the X 99. The transformation principally in¬volved raising and reinforcing the wing, increasing the track of the undercarriage, the addition of spoilers to change the machine into a conventional three axis control aircraft and finally the adoption of the Hirth motor.

The prototype made its first flights at the beginning of 1982 above the Californian desert near to Salton Sea. For the distribution of this aircraft, George Borgeaud built a factory at Monthey in the Vallais area in Switzerland. Shown at the first European Salon of Microlights at Lyon Bron in Septem¬ber 1982, and later at the microlight assembly at Blois in France, this machine met with considerable success amongst the established pilots at whom it is aimed. Georges has consistently followed an intelligent sales policy, hinged on safety, and will only sell this aircraft in Europe to qualified private pilot’s licence holders.

Ready to fly X 99s cost US$8650 in 1983 ex works for the standard version, trailer included. Standard are compass, ASI, altimeter, rev counter and CHTG. As an option, it can have climb, turn and slip gauges. Its spoilers can be used together as air brakes and the machine can be flown solo (from the front seat) without any modification. The rear seat can be replaced by a large supplementary fuel tank and other options include skis, floats, pod, main wheel fairings, dual controls, a second instrument panel for the rear seat and a three blade propeller.

Georges was working on a new wing design which can be rigged in two different spans 32.8 ft or 45.9 ft (10.00 or 14.00 m), and the larger span would bring the X 99 comfortably within British ultralight law.

Single seat single engined high wing monoplane with conventional three axis control. Wing has unswept leading and trailing edges, and constant chord; cruciform tail. Pitch control by elevator on tail; yaw control by fin mounted rudder; roll control by half span ailerons; control inputs through stick for pitch/roll and pedals for yaw. Wing braced from below by struts; wing profile Ga 549; double surface. Undercarriage has three wheels in tricycle formation; steel spring suspension on nosewheel and glass fibre suspension on main wheels. Push right go right nosewheel steering connected to yaw control. Brakes on main wheels. Aluminium tube framework, with pod. Engine mounted below wing driving pusher propeller.

Two prototype examples of this machine were on show at Friedrichshafen in March 1983, but the Wildente did not fly for the first time until 16 April. This machine has a welded tubular framework, which appears to have great rigidity and is also claimed to allow derigging and rigging in less than 10 min. It is sold built and ready to fly. Options include wheel fairings and a three blade propeller.
