Abstract
A vertical takeoff and landing aircraft is disclosed that includes a support structure having a motor mounted vertically thereto, with the motor having a propeller for rotation in a horizontal plane. A power supply for the motor is mounted to the support structure below the motor and electrical coupled thereto. A plurality of fins are attached by their first end to the power and extending radially outward therefrom. Vertical posts have there first ends attached to the second end of the fins and extend upward to the plane of rotation of the propeller. A ring is mounted horizontally to the second ends of the plurality of vertical posts surrounding the propeller. The torque produced by the drag of fins as the aircraft rotates in the opposite direction reacting the torque of the propeller equal to the torque of the propeller necessary to achieve hover. The rotational inertia of aircraft is made equal to the rotational inertia of the propeller.
