Our First Prototype
Our first hovercraft build is a 16-motor coaxial multirotor architecture arranged in a symmetric annular planform. Designed for human-mounted operation, the operator stands centrally above the thrust plane in a hoverboard-aligned stance, aligning the combined center of mass with the thrust axis. At full power, the platform delivers ~260 kgf peak static lift, providing thrust margin for controlled hover, transients, and fault-tolerant operation.
