The Swarm features a garden chair on a sleigh-like frame with an umbrella over the head of the pilot for protection.
Although he never flies much higher than about fifteen feet in the air, the video demonstrates the helicopter’s apparent ease of control.
He writes: “The Swarm man carrying multi-rotor airborne flight testing montage. 54 counter-rotation propellers, six grouped control channels with KK2.15 stabilization. Take-off weight 148kg, max lift, approx. 164kg. Endurance 10 minutes. Power approx. 22KW.”
He ends his description by observing there is a major flaw in the design of the vehicle.
“That is the large number of props running at high speed means the net torque reactions are relatively low, so the craft has little yaw authority. So it probably needs a tail rotor for spot turns.”
