  "textContent": "An aircraft vehicle includes an elongated spine element with a first and second end, and an elongated lift boom at the first end, extending perpendicular to the spine. The vehicle features a left coaxial counterrotating rotor assembly with a front rotor blade and motor, an aft rotor blade and motor rotating in the opposite direction to the front rotor blade, and a servo motor for tilting the assembly. Similarly, it has a right coaxial counterrotating rotor assembly with a front rotor blade and motor, an aft rotor blade and motor, and a servo motor for tilting the assembly. Additionally, a tail coaxial counterrotating rotor assembly is situated along the spine, with top and bottom rotor blades and motors rotating in opposite directions to each other. The aircraft includes a power supply for the rotor assemblies and a controller to manage the power supplied to the motors.",
