Crossover Ultralight Aircraft

Reach for the sky

Designing an entirely new aircraft is an extremely complex and thrilling undertaking, it requires very advanced styling and engineering skills so we were very pleased by this challenge -  to fulfil a man's vision to fly. To meet the requirements for this aircraft, each gram was important. So, due to its impressive weight/resistance ratio, fuselage, aerodynamic surfaces and some other components are made of carbon fibre reinforced polymer (CFRP) .

The Crossover was born out of one of our client’s desire to fully develop an ultra-light aircraft from the ground up. We were responsible to run from the conceptual phase, styling and CAD modelling right up to the aerodynamics, FEA, mechanical engineering, moulds and construction consultancy.

The design was inspired by an academic project from the 70’s called the “FS29”. The project was too advanced for the technology available at the time, so it remained at the prototype stage at that time. Meanwhile, with this new challenge, that one proved to be a perfect starting point. The Crossover draws specifically from the wing system, which had a custom designed wing span morphing.


Ever since the first draft, the challenge was to come up with a hybrid configuration of crossover and glider. Performance balance had to be fine-tuned so it could adapt to both high-speed manoeuvring and a sailing configuration.

Since it was a aircraft built from scratch, every little detail had to be thought and drawn, including flight controls, landing gear and propellers retractable system. Every load conditions were calculated to assure fully compliance with CS-VLA certification specifications.

To achieve the feeling of a sports car in the sky, several decisions were made early in the design process such as the two seater side-by-side configuration and car-like access to the cockpit. Weight had to be kept to an absolute minimum so carbon fiber is profusely used in the Crossover and it is powered by two lightweight electric motors.
