Name & Inspiration

Astrae is derived from Astraeus, a figure associated with the stars and open skies. The name reflects the frame’s sleek, intentional design and its focus on composed, confident flight in open airspace. Every line and proportion of Astrae is deliberate, low-profile, stealth-inspired, and built to feel stable at speed while remaining precise and controlled up close.
