Ultrasports RB1

RB1 / Lightning DS

The Ultrasports/Southdown Sailwings RB1/Lightning DS is a single seat single engined flex wing aircraft with weight shift control. Rogallo wing with fin. 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; floating cross tube construction with > 75 % double surface enclosing cross tube; preformed ribs. Undercarriage has three wheels in tricycle formation; optional steel spring suspension on nosewheel and no suspension on main wheels. Push right go left nosewheel steering independent from yaw control. No brakes. Aluminium tube trike unit, with optional pod. Engine mounted below wing driving pusher propeller. Trike unit has pod.

The RB1/Lightning DS was constructed specially for an attempt on the world microlight altitude record, it consists of a specially lightened Tripacer trike unit with a big Southdown Sailwings Lightning DS wing, more usually found on two seaters.

The engine, an experimental unit from British Robin importer Nicklow Engineering, consisted basically of two Robin 250 cc barrels on a 440cc crankcase, giving the benefit of 488cc without expensive machining. To in-crease the power still further, the cooling fan is removed, the engine relying on free air cooling.

Even in its original form the trike did the job it was designed to do, taking Bob Calvert to a new world record of 19,250ft (5900m) off the Lan¬cashire coast on 19 February 1983 and breaking by over 3000 ft (900 m) Bob’s own record set a year earlier in a Mainair Tri Flyer 330.

Ultrasports Panther

Panther 250 / Solar Wings Typhoon

The Ultrasports/Solar Wings Panther 250 is a single seat single engined flex wing aircraft with weight shift control. 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; floating cross tube construction with 80% double surface enclosing cross tube; preformed ribs. Undercarriage has three wheels in tricycle formation; optional steel spring suspension on nosewheel and no suspension on main wheels. Push right go left nosewheel steering independent from yaw control. No brakes. Aluminium tube trike unit, with optional pod. Engine mounted below wing driving pusher propeller.

Ultrasports’ Tripacer trike unit is a simple mono pole design and can be found attached to a wide variety of wings, the Hiway Demon being a particularly popular choice. Ultrasports teamed up with British hang glider manufacturer, Solar Wings, to market its trike units as complete aircraft under the name Panther.

The cheapest Panther is the 250, which consists of a combination of the Tripacer 250 trike unit and Typhoon S wing. The trike unit has been updated for its new role by the addition of optional front suspension, and if required can still be bought without wing, either complete or as a kit. Power comes from a single cylinder Robin engine of 250 cc, driving through V belts. At one time all Ultrasports trike units used V belt transmission, but by 1982 all but the 250 have been engineered for toothed belts.

A glass fibre and nylon pod is optional.

The Ultrasports/Solar Wings Panther 330 is a weight shift single seat single engined flex wing aircraft with weight shift control. 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; floating cross tube construction with 80% double surface enclosing cross tube; preformed ribs. Undercarriage has three wheels in tricycle formation; standard steel spring suspension on nosewheel and no suspension on main wheels. Push right go left nosewheel steering independent from yaw control. No brakes. Aluminium tube trike unit, with optional pod. Engine mounted below wing driving pusher propeller.

The Panther 330 was Ultrasports’ main single seater. Although structurally similar to the Panther 250, the twin cylinder model has been considerably updated for 1983. Not only does it include as standard the trailing link and coil spring front suspension which is optional on the 250, but a new engine mounting system has been devised, placing the Robin ‘right way up’ and thus giving much more clearance between propeller and ground. It also eliminates plug fouling when the aircraft is left standing. A further change is the use of a stronger rear axle, of 11/8 inch (29min) diameter.

Like the Panther 250, the Panther 330 is sold as a complete aircraft and uses the Typhoon S wing. However, it too can be bought without wing if desired, in which case the trike unit reverts to its original name of Tripacer 330. A pod is optional.

The Ultrasports/Solar Wings Panther Dual 330 is a weight shift tandem two seat single engined flex wing aircraft with weight shift control. 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; floating cross tube construction with 50% double surface enclosing cross tube; preformed ribs. Undercarriage has three wheels in tricycle formation; steel spring suspension on nosewheel and no suspension on main wheels. Push right go left nosewheel steering independent from yaw control. No brakes.
Aluminium tube trike unit, with optional pod. Engine mounted below wing driving pusher propeller.

The Panther Dual is Ultrasports’ replacement for the Puma. As with the single seat Panthers, the Panther Dual in both 330 and 440 forms uses a Rogallo from Solar Wings, in this case the Typhoon XL model. The change from a Southdown wing, is not, however, likely to radically alter the flying characteristics of the aircraft, as the wing areas are identical and both are concealed floating cross tube designs. The Typhoon XL is a little heavier (122 lb, 55 kg against 106 lb, 48 kg) and has less double surface and a conventional keel pocket rather than a fin. With British airworthiness regulations in mind, the XL has been static tested to 1.85 Imp ton (2.07 US ton, 1.88 tonne), a load which produced no permanent deformation of the structure.

The trike unit is similar to that used for the Puma but has been updated in a parallel fashion to the single seater, with front sus¬pension by trailing link and coil spring and an engine mounting ‘right way up’. Toothed belt transmission is standard. A pod is optional.

The Ultrasports/Solar Wings Panther Dual 440 is a weight shift single seat single engined flex wing aircraft with weight shift control. 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; floating cross tube construction with 80% double surface enclosing cross tube; preformed ribs. Undercarriage has three wheels in tricycle formation; standard steel spring suspension on nosewheel and no suspension on main wheels. Push right go left nosewheel steering independent from yaw control. No brakes. Aluminium tube trike unit, with optional pod. Engine mounted below wing driving pusher propeller.

Ultralight Soaring Wizard

Wizard J-3

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.

Nick Wrigley’s UAS com¬pany was one of the pioneers of triking in Britain and produced the first ever two seat trike unit, which it showed at the Welles¬bourne fly in in 1980. He called it the Storm Buggy after the Solar Wings Storm wing to which it was mated, and fitted it with a 400 cc Solo engine, direct drive and side by side seating.
Nick converted the Storm Buggy to single seat configuration and used it for various sporting events until 1981, when serious production of single seaters began, using initially the 340 Sachs engine, toothed ¬belt reduction, and his own newly developed three bladed nylon propeller. Although still called Storm Buggy, this model was suitable for a wide variety of Rogallos and by 1982 was usually found with a Flexiform Sky Sails Medium Striker wing.
Storm Buggys were later produced with Robin EC44 engines and in addition some two seaters found their way out of Nick’s workshop, using Flexiform’s Dual Striker wing.

UAS ceased trike production at the end of 1982 to concentrate on propeller design.

Ultralight Flight Phantom / Phantom Aircraft Phantom XI / X2

Phantom X-1

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.
