Eight systems,
one airframe.

Every component earns its weight. Below is the full breakdown of what keeps Pralay V1 stable, aware, and airborne.

Measured at sea level, 20°C, no wind. Payload figures exclude the gimbal camera.

TOP SPEED
97KM/H

A 420mm carbon-fiber diagonal frame keeps the mass low and the center of gravity centered directly beneath the rotor plane, so the airframe stays predictable even at full throttle.
