The FX1 configuration comes from careful consideration of how best to meet all the requirements that define a superlative, modern sport-plane.  has been carefully engineered to optimize all aspects of a proven configuration.

(Engine Placement) Mounted “front & center” off the leading edge of the wing, the FX1’s engine location provides a number of important benefits:

Improved forward visibility, a prime factor for flying enjoyment and safety.

A comfortable cabin with less noise and vibration. With the exhaust pipe above the wing, the FX1 is also quieter for people on the ground.

Aerodynamic and handling advantages:

Accelerated Lift & Control Response

Very close to the wing, the propeller directs accelerated airflow over the wing (“accelerated lift”, a phenomenon common to twin engine designs), enhancing take-off performance. This effect also tames departure stall characteristics, contributing to the FX1’s forgiving flight qualities. In a similar way, the propeller is also closer to the vertical and horizontal stabilizers and associated control surfaces (rudder & elevators) for enhanced control response.

CG & Balance

As with “mid-ship” engine placement common for exotic sports cars, the FX1’s engine mass is closer to the aircraft’s center of gravity, decreasing the aircraft’s moment of inertia for faster response in the pitch & yaw axes. For the roll axis, raising the engine to the level of the wings on a high-wing design increases roll response.

Experience with the FX1’s predecessor, the JetFox 97, has proven that a “front & center” engine placement offers an important safety feature. In the event of an impact, rather than having the engine transmit force directly to the cabin, a forward impact is transmitted to the airframe, independent of the cabin, for greater survivability. The FX1’s cabin is one of the strongest in the industry, employing a cage of built-up welded steel-alloy tubing (chromoly), wrapped in a carbon-fiber composite structure for the utmost in strength and rigidity.

The Ideal Light Sport Seaplane

Another significant advantage of the FX1’s engine placement applies to the float-plane application, where the engine and propeller are located far above the water, allowing the FX1A to serve as a very capable amphibian, as proven by a JetFox-based prototype amphibian which exhibited excellent handling and performance.

The JetFox based amphibian prototype proved the theory that a tractor configuration is more suitable for a seaplane than a pusher configuration – a “pulling force” facilitates “getting on the step” as compared to a “pushing force”. The amphibian prototype was test-flown in Europe, the United States, and in Asia. All FX1 airframes are designed to adapt to the amphibian role with the easy addition of optional floats, making every FX1 a potential amphibian aircraft.

Most customers have long demonstrated a preference for side-by-side seating. The FX1 optimizes this configuration with a strong, spacious cabin. Large car-like doors give unmatched ease of entry and egress.

A side-stick control system, as in modern airliner and fighter jets, provides an unobstructed cabin (a conventional center joy-stick is standard).

The instrument panel is located to maximize outward visibility, with room for optional high-tech electronic flight information systems (EFIS “glass-cockpit” avionics) that integrate all flight parameters into twin 10” redundant LCD flight and engine instrument touch-screen displays. Switches, warning lights, and controls are ergonomically placed.

Cabin heat, & ventilation, lighting, adjustable seats and an in-flight accessible stowage compartment round out a well appointed, stylish cockpit that maximizes comfort and flying pleasure. For safety, the cabin is immensely strong, combining a lightweight welded cage of aircraft chrome-moly steel tubing and an ultra stiff outer covering made of molded carbon graphite, for a lightweight cabin that is one of the strongest in the industry.


Wing: The FX1 is a high-wing design, offering better downward visibility than a low -wing configuration. High wing airplanes are very stable at slower speeds, and can right themselves more quickly in turbulence, and placing the engine above the fuselage raises the center of gravity, for quicker control response than conventional high-wing designs.

Landing Gear

A majority of sport-plane buyers prefer the FX1’s tri-gear configuration, as it is easier to master than “conventional-geared” aircraft equipped with a tail wheel.  The main-gear are made of strong fiberglass, an ideal material for the absorption of a hard-landing impact. This combination, along with ease of handling makes the FX1 particularly suited as a flight trainer.

Flight Qualities

The criteria for good performance is multifaceted, and goes far beyond a single measure, such as cruise speed. The key is to find an ideal balance in all areas and the FX1 is a good example of a balanced design. Di Cesare has succeeded in creating an airframe that is aerodynamic, light, rigid and strong.

Stability and Handling

Stability and control response are important for flying pleasure and safety. As a high-wing aircraft with the engine mounted on the wing, and with large aerodynamically efficient control surfaces, the FX1 achieves a good balance between stability and control response.

The configuration and dimensions of the FX1 provides great stability in pitch, yaw and roll, which is important while flying in turbulence and for flight training.

Good control response results from a combination of the dimensions and placement of all control surfaces, and the link between them and the pilot. Superior controls must be free of resistance and play. The FX1’s controls are ergonomic and free of play.

Good handling also relates to the limits of control, and the manner in which an aircraft responds to recovery inputs following any loss of control. The FX1 is a “forgiving” aircraft, an important safety factor.

The FX1 is made of a combination of high-tech and conventional aircraft materials, for the benefits that each offers, using proven aircraft design and engineering practices. The result is a very rigid airframe with a high strength-to-weight ratio, greatly resistant to fatigue and corrosion, giving the FX1 ruggedness and durability.

Much of the fuselage, cabin, engine cowl, and aerodynamic components are made of carbon fiber, an ideal corrosion-proof material for aircraft, providing high strength, great resistance to heat and fatigue, and an elegant finish.

Aluminum alloys (2024 & 6061) are widely used in aviation for ease of construction, inspection, and repair, and for predictability and durability. The FX1’s wing, empennage and control surfaces are all made of durable aluminum.

Aircraft Steel Alloy

Chrome-Moly steel aircraft tubing is another important material that provides great strength. The cabin of the FX1 is surrounded by a steel cage, for the utmost in rigidity and protection.

Fiberglass Composites

Fiberglass is utilized for the landing gear. It is ideal in that application, given its flex properties. It will absorb an energy readily in the event of a hard landing, will not corrode, and has a very low fatigue index.
