Heavy lift
Heavy-lift rotor at full spin

From the archive
How the ring wing got here: early designs, before the pushers, steered by vanes and control frames.
EIVIE e-VTOL
The film that played on our earlier website.
2022 prototype, vane steering
An early design with no pusher propellers, steered by vanes under the ring wing: lifting off, passing close overhead and flying off over the hoop houses.
Transition flight, side view
The 2022 transition flight from a second camera: the ring in forward flight, steered by the two vanes under it.
Hover, field test
An early ring wing on four rotors, no pushers, hovering and holding its position over a field.
Cross-form ring, close up
An early ring wing seen from below: a cross-shaped control frame and propellers inside the ring, no pushers.
Early prototype, hover at dusk
An early subscale prototype with cross-form control surfaces, hovering and turning overhead at dusk.
