249 g. Folds to the size of a paperback. Flies itself for 42 minutes.
FLYFour arms, one hinge each, zero tools. Two seconds from pocket to props-hot — and the flight computer is already talking to the sky before the last arm clicks home.
Six time-of-flight arrays and a 240 TOPS neural core rebuild a 26-metre mesh of the world forty times a second. Trees, wires, the corner of a barn — routed around before you would have seen them.
40 Hz nav-mesh refreshTrack-Lock re-acquires a target after four seconds of full occlusion by predicting where it went, not by hunting for where it was. Lock a trail runner in dense pine and the frame simply stays honest.
4.0 s occlusion toleranceLose the link and HELIX retraces its own visual odometry, landing inside a 0.4 metre circle of where it left — no GNSS, no controller, no drama. Every flight is logged to the airframe, not the cloud.
0.4 m blind-return accuracy
Low light is where micro-drones normally give up. HELIX opens the aperture, drops the shutter to 1/30 and lets the gimbal carry the difference.
Controller link, clear line of sight
Service ceiling, ISA conditions
Sport mode, no payload
Hover, 20 °C, no wind
Measured, not modelled. Full test methodology ships with the airframe.
