Automatic control device for flying state of remote-control toy airplane

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