ABSTRACT:
The present invention relates to an automatic detector for a control device for controlling the flying state of a remote-control toy airplane, which can provide automatic correction to maintain the remote-control toy airplane in a flying state in a level or horizontal manner. The detector is a digital or analogic device located at a proper position within the housing of the airplane. The detector includes a device locating plate, fixing racks, a suspension cord, a movable light-obstructing sheet or a movable light-permeable sheet, light emitting element, and one or more detecting elements the light-obstruction sheet is swingingly mounted on the suspension that in turn is connected to the cord fixing racks. When light emitting element emits light and the airplane maintains a horizontal or level attitude, the effect of gravity on light-obstruction sheet will cause it to obstruct light. If the airplane is not horizontal, the light source will not be obstructed and will be detected by a detecting element to give signals respectively to a control unit, which will provide signals to an alternative unit whose output signal will cause the airplane to fly toward the right side or left side, to turn left or right, or to correct correcting engine thrust to maintain the airplane in an optimal flying condition.
