Zuri has eight electromotors with big rotors. Having less rotors would be dangerous, having more would reduce efficiency.
All flight phases are controller by autopilot. During vertical flight, the onboard computer controlls stabilization. Its reaction speed trumps that of a human by orders of magnitude. The autopilot ensures smooth movement and compensates for the force of the wind blowing.
Horizontal flight is controlled by a fly-by-wire system, similar to what's used in other modern airplanes.
