Following the transition flight of its large-scale prototype in May 2025 that validated the company's patented fan-in-wing technology, Horizon has been designing and building its full-scale hybrid-electric VTOL aircraft.

The Canadian developer is progressing IFR and known-icing capability for its Cavorite X7, supported by new all-weather propulsion testing funded by an INSAT grant.

Project CRYSTAL (Canadian Research Yielding SusTainable All-weather Lift system) will focus on developing and testing an all-weather vertical propulsion system for aircraft like Horizon's hybrid eVTOL, the Cavorite X7.
