French manufacturer Aquilair wants you to get in the “swing” of triking with their 2-seat trike, the Swing. The trike’s sporty name identifies what the French company calls their “chariot” (chassis or carriage). The name may also derive from the company’s unique fold-down system. Most trikes pivot at the base of the mast (the component connecting occupants and engine to wing) or at a mid-mast point about engine height. Aquilair pivots the mast under the front seat – or the only seat in the case of their single-place model, the Kid. Placing the pivot point this far forward allows the company to offer easier lifting of the wing into position without using weighty and costly gas struts. The result is a simpler, lighter package that accomplishes the goal of letting one person erect the trike from its transport state. The feature is driven, I was told, by the 90-pound female owner of Aquilair.

Design
Cosmetic appearance, structural integrity, achievement of design goals, effectiveness of aerodynamics, ergonomics.
Pros - More intriguing differences than any trike I've flown. Several special characteristics: easily lifted wing, adjustable nose fork, lower center of gravity. Ingeniously designed by a brother for his sister who owns company. Has French certification. People-friendly design in various ways.
Cons - French certification methods and reliability are not well known in the USA. Though machine has unique qualities, they may have to be shown to you (however, some are obvious). Distinguishing fold-down system was not performed for article.
Systems
Subsystems available to pilot such as: Flaps; Fuel sources; Electric start; In-air restart; Brakes; Engine controls; Navigations; Radio; (items covered may be optional).
Pros - Easily reached kill switch (even by foot). All wiring is kept inside the airframe for protection. Electric start available. Built-in fuel tank (available in various sizes); you fill it by pivoting forward the rear seat. Brake has parking feature; useful when lifting wing.
Cons - It's a trike, therefore no flaps to aid landing approach. Though electric start is featured on top model (similar to test ultralight), this one was pull started. Little room available for a panel mounted radio.
Cockpit/Cabin
Instrumentation; Ergonomics of controls; Creature comforts; (items covered may be optional).
Pros - Entry and exit enhanced by low profile and open-sided seats. Well-formed and padded seats. Adjustable nose fork - slides fore and aft - adjusts for pilots of different heights. Dual steering controls and unique combo throttle, emergency kill switch to prevent runaway engines, etc. Angled mast prevents "helmet buzz" for rear occupant.
Cons - Panel area is limited, preventing installation of certain electronic instruments. No side area to give illusion of enclosure. No shoulder belt was fitted to front seat pilot (though one is installed for the rear seat and is available for the front). Very open cockpit may not appeal to those in cold climates.
Ground Handling
Taxi visibility; Steering; Turn radius; Shock absorption; Stance/Stability; Braking.
Pros - Ground behavior is much better than many trikes owing to low center of gravity and well-suspended carriage. Rear suspension is designed to have little rebound. Trike visibility is always good and they are easier to maneuver on the ramp than a fixed-wing ultralight.
Cons - Nosewheel brake is not particularly strong (common on nosewheel brake ultralights). Low posture means less ground clearance for rough fields (though factory touts the safety of the full pod in the event of heavy landings - it can skid while protecting pilot, they say).
Takeoff/Landing
Qualities; Efficiency; Ease; Comparative values.
Pros - Very straightforward takeoffs and landings (common to many trikes). Excellent visibility during all takeoff and landing operations. Reasonably short takeoff roll (under 200 feet). Very stable during takeoff roll due to lower center of gravity and good suspension. Brake can help on hard surfaces.
Cons - Flying solo ground roll seemed slightly longer than expected. All trikes show some weakness in crosswind landings (though instructors can show ways to compensate). Brake is not particularly powerful.
Control
Quality and quantity for: Coordination; Authority; Pressures; Response; and Coupling.
Pros - A somewhat forward control bar position was not uncomfortable, but permitted a deep pull-in as is sometimes needed (flown solo - may have been configured for dual). Ground effect seemed strong perhaps due to a lowered wing height. Trikes generally coordinate easily if you know the technique. La Mouette wing a good choice for better handling.
Cons - With the control bar more forward, push-out is limited (though I found no deficiency as a result). Some overbanking tendency noted (found on many trikes). Precision turns in trikes are more challenging. No other negatives.
Performance
Climb; Glide; Sink; Cruise/stall/max speeds; Endurance; Range; Maneuverability.
Pros - Trike purported to be more efficient due to the lower height profile; hard to judge but performance seemed quite strong. Forward control bar position allowed generous pull-in with liberal power, resulting in faster dives. Factory says the shorter mast allows engine thrust to act more directly on the wing.
Cons - Climb didn't seem as strong as I expected for a powerful trike flown solo. Endurance is not great with standard 10-gallon tank and fuel-guzzling 65-hp Rotax 582.
Stability
Stall recovery and characteristics; Dampening; Spiral stability; Adverse yaw qualities.
Pros - Stalls were mild at any power setting or in turns, however, I must note that the forward-positioned control bar may not have allowed as deep a stall as I commonly do. Wing stayed level in stalls. Longitudinal stability investigation was positive. No adverse yaw (like most trikes).
Cons - Stalls were at a slightly higher speed than I expected. All trikes nose up on power addition, though the control bar position helped control this reaction. Some overbanking tendency noted (common on many trikes), and this must be controlled in steeply banked maneuvers.
Overall
Addresses the questions: "Will a buyer get what he/she expects to buy, and did the designer/builder achieve the chosen goal?"
Pros - Aquilair of France in business for 11 years; U.S. distributor has even more experience. Fully built ultralight. Single-seater and other models available. You can't buy this combination of features in another trike. Available without fairing for less money. For those with plenty of money a 4-stroke and floats are coming.
Cons - Imported design of lesser fame; may affect resale values. Middle of overall trike price range; still nearly $19,000. U.S. representation is presently in Florida, a long way from many flying sites.
