Platform

4+1 QuadPlane Architecture

Four lift motors handle vertical takeoff and landing. One pusher motor drives efficient cruise. The best of both worlds — no runway, maximum range.

How It Works

The Stork uses a QuadPlane configuration managed by ArduPilot. This architecture combines VTOL convenience with fixed-wing efficiency in a single airframe.

1

Vertical Takeoff

Four lift motors spin up and lift the aircraft vertically from any 3×3 m clearing. No runway needed.

2

Transition

The pusher motor engages while lift motors gradually reduce thrust. The wing takes over as speed builds past stall speed.

3

Cruise

Lift motors stop entirely. The pusher and wing provide efficient fixed-wing flight at 54–60 km/h, covering up to 130 km.

4

Return Transition

As the aircraft approaches its destination, lift motors restart and the pusher slows. The aircraft bleeds speed and enters hover.

5

Vertical Landing

Precision GPS-guided descent to the landing zone. Fully autonomous — no pilot stick input required in AUTO mode.
