Abstract
Several embodiments of remote controlled helicopters wherein the longitudinal position of the helicopter is controlled by means of a tether wire affixed to the rear of the helicopter. In some embodiments, the connection of the tether wire to the fuselage is such that at least a portion of the torque created on the fuselage by the rotation of the main rotor is absorbed by the tether wire.
Claims12
A remote controlled helicopter having a fuselage, a rotor journaled for rotation about a generally vertically extending axis by said fuselage, power means carried by said fuselage for driving said rotor, said rotor and said power means being operable for varying the direction said helicopter travels and its height above the ground, remote control means for operating said helicopter from a remote location for varying the height said helicopter flies above the ground and the lateral position of said helicopter from a fixed point on the ground, and flexible tether wire means connected to said fuselage at a point rearwardly from said rotor axis and to said ground at said fixed point for limiting the distance, and thereby height also, of said helicopter from the fixed point on the ground without restraining the direction of travel or lateral position within a selected length of said tether wire.
