Marshall Aerospace Delivers 6-DOF Model for Cavorite X7 VTOL

On June 9, 2026, Marshall Aerospace delivered a six degrees of freedom (6-DOF) flight dynamics and control model to New Horizon Aircraft Ltd. (Horizon Aircraft), marking a critical software milestone for the Cavorite X7 hybrid-electric vertical take-off and landing (eVTOL) program.

In a press release issued by Marshall Group, the company confirmed that the delivery of the steady level flight model will allow Horizon Aircraft to predict and optimize the aircraft’s response to control inputs. This Software variant is the first of several planned models designed to support the development of a safety-critical control system as the Cavorite X7 advances toward Certification.

Advancing the Cavorite X7 control systems

The 6-DOF model simulates the aircraft’s behavior across all rotational and translational axes. Marshall Aerospace’s Aero Engineering Services division developed the software following a competitive tender issued by Horizon Aircraft in 2025.

“The delivery of the first flight model for the Cavorite X7 marks a strong start to our Partnerships with Marshall Aerospace,” stated Tom Brassington, Chief Technology Officer at Horizon Aircraft. “Marshall’s engineers have integrated seamlessly into our development process, serving as an extension of our team and applying their expertise to developing one of the safest, toughest, and most performant modern VTOL aircraft.”

Mark Hewer, Aero Engineering Services Director at Marshall Aerospace, noted that the program demonstrates the company’s ability to translate engineering experience across complex challenges, including platform modifications and test beds. Hewer added that the company is prepared to support Horizon Aircraft through the safety-critical development work required for commercial and military aviation applications.

Development timeline and fan-in-wing technology

The Cavorite X7 is a dual-use hybrid-electric VTOL designed for both commercial and military operations. It features a patented fan-in-wing design that utilizes lift fans for vertical takeoff before transitioning to forward flight. According to the Manufacturers, the aircraft is projected to offer a 75% cost-efficiency advantage compared to conventional helicopters.

Horizon Aircraft validated the fan-in-wing technology during a successful transition flight of a large-scale prototype in May 2025. With the initial steady level flight model now delivered, Marshall Aerospace is developing additional flight regime models to support the ongoing certification process.

Horizon Aircraft expects to complete the assembly of the full-scale Cavorite X7 in late 2026. Flight testing of the full-scale aircraft is scheduled to commence in early 2027.

AirPro News analysis

We note that the partnership between an established aerospace engineering firm like Marshall Aerospace and an emerging VTOL developer highlights a maturing phase in the advanced air mobility sector. By outsourcing complex, safety-critical flight dynamics modeling to a legacy contractor, Horizon Aircraft reduces its developmental risk and leverages established certification experience. The successful integration of the 6-DOF model will be a crucial technical gate before the Cavorite X7 can safely transition from hover to forward flight in full-scale testing next year.
