The Vickers Aircraft USA FAST4 is a four-seat, single-engine piston aircraft whose development programme has been unveiled by the company. As AVweb reports, the design centres on an all-carbon-fibre airframe, folding wings and a target cruise speed of 235 KTAS, though no engine selection, pricing, first-flight date or production timeline has been confirmed.
The FAST4 represents a substantial step up in ambition from a company that only recently completed flight testing on its WAVE amphibian. Whether the published performance targets prove achievable will be the question to watch as the programme matures.
What the Vickers Aircraft USA FAST4 Is Designed to Do
Central to the FAST4's appeal is the promise of four adult occupants aboard with full fuel, removing the familiar compromise between passenger capacity and range. AVweb reports that Vickers is targeting a useful load of 1,520 pounds alongside a fuel capacity of 102 gallons, with 1,300 nautical miles achievable at the 235-knot cruise speed.
For a piston-engined general aviation aircraft, those numbers are aggressive. A 1,300-nautical-mile range at speed puts transcontinental sectors within reach for a four-occupant single.
The design specification includes both IFR capability and a BRS whole-aircraft parachute system, as AVweb notes. For the cockpit, Vickers is weighing up Garmin AXIS flight displays and Autoland technology as potential avionics choices.
The Layout and Materials
The FAST4 will use a low-wing layout and an all-carbon-fibre airframe. Vickers says it has already conducted destructive testing of its carbon fibre manufacturing technology, which gives the structural claims at least some grounding in physical hardware rather than purely on-paper targets.
Folding wings feature prominently among the practical ownership benefits Vickers is promoting with the FAST4. AVweb notes that the company anticipates a 50 per cent reduction in hangar footprint as a result of the folding wing arrangement. In a market where tie-down and hangar costs across the United States continue to climb, that figure carries genuine commercial weight.

The Link to the WAVE Amphibian
Rather than beginning entirely afresh, Vickers is carrying technology forward from the WAVE, a single-engine amphibian whose flight testing wrapped up in 2023. The WAVE is now working through the certification process, according to AVweb, providing a proven technical foundation on which the FAST4 programme can build.
The company intends to share components and systems across both aircraft. That strategy is intended to reduce unit costs on each type by spreading development and supply-chain investment across a broader production base. It is a logical approach for a small manufacturer, though it also means the FAST4 programme is in some ways contingent on the WAVE programme proceeding successfully.
Where MOSAIC Fits In
Vickers expects the FAST4 to benefit from the FAA's MOSAIC regulations. MOSAIC introduced expanded certification requirements under Part 22 in July, according to AVweb, and is widely seen across the general aviation industry as opening a broader route to market for new designs.
For Vickers, MOSAIC is relevant because Part 22's scope could allow a more straightforward path to certification than traditional light aircraft rules would permit. The FAST4's specification, including its four-seat layout and performance targets, appears designed to sit within that expanded framework.
Production and Next Steps
Vickers intends to manufacture both the FAST4 and the WAVE in the United States. Discussions with several states over a potential production site are already underway, according to AVweb, though no location has been confirmed.
For now, though, the programme is still in its early stages. No engine has been selected, no first-flight date set, no production facility named and no pricing announced. What Vickers does have is a thoroughly detailed specification, a materials technology base that has been validated through destructive testing, and a regulatory framework the company believes is compatible with the design.
For readers who follow general aviation development closely, the gap between a well-specified concept and a certified aircraft in production is wide. Vickers will need to close that gap on two programmes simultaneously, the WAVE certification and the FAST4 development, while also securing a manufacturing home.

The Bottom Line
The FAST4 is an eye-catching concept. A 235-knot, 1,300-nautical-mile, four-seat piston aircraft with folding wings, whole-aircraft parachute recovery and Autoland capability would be a genuinely competitive product in the upper end of the general aviation market, if it reaches production at a price the market will bear.
The performance targets are ambitious for the category, and several key decisions, including engine selection, remain unmade. Vickers is, however, not working entirely without foundation. The WAVE programme gives it a tested manufacturing method and a developing certification relationship with the FAA, and MOSAIC provides a more accommodating regulatory backdrop than existed a year ago.
Whether those foundations are enough to carry two aircraft to market is the question the next few years will answer. We will report on the FAST4 as firm programme milestones are announced.
