Abstract
Abstract The present invention relates to a remote control mylar toy aircraft and, more particularly to an inflatable mylar toy aircrat includes a remote receiver to control two motors, fitted with balance weights and a suspending balance strip. After having been inflated, the mylar toy aircraft is remote controlled to fly forward or backward, or to turn aside, or to move upward or downward. When the mylar toy aircraft stands still in the air at a certain height from the ground, it is controlled by the balance strip to prevent it from dropping to the ground or flying away. By means of relatively rise and fall adjustment between the balance weights and the balance strip, the flying height of the mylar toy aircraft is properly adjusted.

A remotely controllable toy aircraft, consisting of in combination, a body made of light material and being inflatable by a gas lighter than air, said body having a center of gravity, a receiver box detachably connected to said body whereby the weight of said body, said receiver box acts on the center of gravity of said body, said receiver box including in the interior thereof a remotely controllable receiver fitted with a receiving antenna and several units of balance weights, said receiver box comprising a motor tube, two battery powered motors each of which is located at one end of said motor tube, each of said motors being located at each end of said receiver box, said motors being controlled by said receiver and two propellers each of which is connected to each of said motors, a length-adjustable balance strip made of several units of strips in series connection, said balance strip being suspended from the bottom of said receiver box, said balance weights being located above said balance strip, a transmitter spaced from said receiver box, including transmitting means and a control keyboard, for transmitting a signal to said receiving box initiated by said control keyboard, said toy aircraft less said balance weights having a certain upwardly directed pull of floatability, the total weight of said body, said receiver box, said balance weights and said balance strip being greater than said floatability whereby a small segment of the rear portion of said balance strip is in contact with the ground to facilitate controlling the floating height of said toy aircraft, the floating height of said toy aircraft being adjustable by increasing the units of said balance weights and reducing the length of said balance strip, or by increasing the length of said balance strip and reducing the units of said balance weights.
