| 摘要 | PURPOSE: To enhance a reduction in weight and obtain autonomous stability by comprising a ring buoyancy body, a body for receiving two variable speed motors, two servo motors and a control unit, a double reversing propeller, and a radio controller, and setting the center-of-gravity position of the whole body lower than the buoyancy center of the buoyancy body. CONSTITUTION: When the stick of a controller is operated to send a signal to a control unit in a body 7 so that the rotating speeds of propellers 18, 24 rotating in opposite directions are increased or decreased in the state where the rotating speeds of the propellers 18, 24 are conformed to each other to cancel the reaction torques of the propellers 18, 24, a radio control flying body is raised or lowered in a stable state without rotating and tilting. When a slight difference in rotating speed is made between the propellers 18 and 24, a difference is made in the reaction torques given to the body 7 by both the propellers 18, 24, the radio control flying body is gently rotated, and this rotating state can be confirmed by a rear confirming fin 32. At this time, the increase or decrease quantity of rotating speed of the propeller 18 is equal to the decrease or increase quantity of the propeller 24, the radio control flying body is never vertically moved.
