The Medway Budget trike uses a Rotax 503 and Raven wing.

The Eclipse R, new in 1998, had a Jabiru four stroke on the double monopole chassis with a Raven wing.

When equipped with a Rotax 503, the trike is marketed as the Hybred, also with a Raven wing.

The Mainair/ Southdown Sailwings Puma MS is a tandem two 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; pre-formed ribs. Undercarriage has three wheels in tricycle formation; no suspension on any wheels. Push right go left nosewheel steering independent from yaw control. Brake on nosewheel. Aluminium tube trike unit, with optional pod. Engine mounted below wing driving pusher propeller. All airframe tubing is bright anodised drawn seamless aluminium to British HT30TF specification. All bolts are aircraft quality AN series.
The Puma MS uses an identical trike unit to the Tri Flyer Two Seater/Dual Striker, but instead of the Flexiform wing a Southdown Sailwings Lightning DS is used.
The Puma Sprint MS is the same as the Puma MS except a 70% double-surface wing.

The Mainair/ Flexiform Sky Sails Rapier is a tandem one/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; bowsprit construction with >70% double-surface; pre formed ribs. Undercarriage has three wheels in tricycle formation; no suspension on nosewheel and rubber supension on main wheels. Push right go left nosewheel steering independent from yaw control. Brake on nosewheel. Aluminium tube trike unit, with optional pod. Engine mounted below wing driving pusher propeller. Trike unit tubing is epoxy sheathed drawn seamless aluminium to British HT30TF specification. All bolts are aircraft quality AN series.
Many people want to take up a passenger occasionally and yet find a full two seater weight shift machine rather heavy to handle. For these pilots Mainair has designed the Rapier, a ‘one plus one’ machine powered by a 330 Robin but capable of lifting a total of 280 lb (127 kg). The Rapier follows Mainair’s two seat practice in using a toothed belt drive and is the first production machine to use the company’s new undercarriage for the main wheels, which incorporates telescopic side struts with internal rubber suspension.
Like the Merlin, the Rapier is a joint venture, this time with Flexiform Sky Sails, whose Striker wing is produced in a special red and white colour scheme to match the epoxy paint on the trike unit. Allied to the elimination of rigging wires on the trike, (in favour of struts) and the underslung fuel tank (done for safety reasons), this gives the Rapier a distinctive appearance.

In 1998 Mainair revived the Rapier name with a new model, unrelated to the model of 15 years before, as an entry-level trike. The new Rapier uses the Blade wing but the trike unit is more basic with n suspension and only the Rotax 503 or 462 as options. It could be purchased in kit form.

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 >70% double surface enclosing cross tube; pre¬formed ribs. Undercarriage has three wheels in tricycle formation; no suspension on any wheels. Push right go left nosewheel steering independent from yaw control. Brake on nosewheel. Aluminium tube trike unit, with pod. Engine mounted below wing driving pusher propeller. A ball race assembly is used to support the front fork for the nosewheel steering. All airframe tubing is bright ano¬dised drawn seamless aluminium to British HT30TF specification. All bolts are aircraft quality AN series.
First shown in October 1982, the Merlin is Mainair’s top of the range single seat trike, and is produced in conjunc¬tion with Airwave. It was conceived as an entity and is marketed that way, complete with purpose designed wing, glass fibre and fabric pod, and instruments.
The Merlin’s most unusual feature is its wing connection, which is a modified form of the French connection often used in hang¬gliding. Developed specially by John Hudson for this application, it is designed to give very light roll control, while absorption bushes reduce torsional loads transmitted to the trike unit.
Standard instrumentation is a Diplex alti¬meter and a Winter ASI; spherical compass, tachometer, CHTG, EGTG and vario are all optional.
Structurally and mechanically the trike unit is similar to the Tri Flyer 330, though the main wheels’ undercarriage is strengthened by using two axle tie wires rather than one.
