PlaneFox tracks 2 MX aircraft for sale and re-reads every one of them from the broker and dealer sites it watches, so the figures below move when the market moves. Every number on this page is measured from those live listings, not taken from a published price guide.
A Quicksilver MX flies about 78 nm, roughly 144 km, which is about 2 h in still air at typical cruise.
A Quicksilver MX costs about EUR 451 a month to run, or about EUR 59 for every flight hour when it is flown 150 hours a year.
The Quicksilver MX is a single-seat, open-frame ultralight aircraft developed by Eipper Formance and later associated with Quicksilver Manufacturing. Introduced around the start of the 1980s, it became one of the defining tube-and-sail ultralights of the early recreational flying era. The MX is distinct from later two-seat Quicksilver models such as the MX II. It is a lightweight, strut-braced, high-wing pusher with conventional three-axis controls, valued by buyers for its simple construction, low operating cost and large installed base.
Typical Quicksilver MX performance depends on engine, propeller, airframe weight and whether the aircraft is operated under ultralight or experimental rules. Common examples use a single-cylinder Rotax 277 two-stroke engine of about 28 hp, while some have been fitted with other small two-stroke powerplants. Published figures for representative MX configurations include cruise speeds around 35 to 40 knots, very low stall speeds, and a service ceiling often quoted near 10,000 feet. Range is modest, commonly limited by small fuel capacity, with many aircraft used for local flying rather than cross-country travel. Useful load is generally in the light-sport ultralight range, commonly around the high 200 lb class on representative factory data, but individual aircraft should be weighed and documented.
The MX has no enclosed cabin. The pilot sits in an exposed single seat beneath the wing, with excellent visibility and minimal wind protection. There is no baggage compartment in the conventional sense, and comfort depends heavily on seat condition, windscreen installation, clothing and local climate. Avionics are usually basic: airspeed indicator, altimeter, tachometer, engine temperature gauges and possibly a handheld radio or intercom. Integrated glass systems such as Garmin Perspective or Garmin G1000 are not typical or appropriate for the MX category.
Used Quicksilver MX aircraft are usually evaluated more like kitbuilt ultralights than certified aircraft. Buyers should inspect sailcloth age and UV exposure, tubing corrosion or damage, cable condition, control hardware, landing gear alignment, engine hours, fuel system condition and the quality of any modifications. Documentation matters, including build records, weight data, operating status and engine maintenance history. Common upgrades include replacement sail sets, improved seats, updated wheels and brakes, ballistic parachutes and alternative small two-stroke engines. In the used market, the Quicksilver MX generally sits as an entry-level recreational aircraft for local, fair-weather flying, with value driven by condition and completeness rather than avionics or speed.
