PROBLEM TO BE SOLVED: To provide a coaxial contrarotating radio controlled (R/C) helicopter having maneuverability and operability sufficient for enjoying manipulating the R/C helicopter indoors by constituting a simple mechanism for driving and controlling rotors. SOLUTION: This R/C helicopter 1 is equipped with a swash plate comprising a lower plate 62, mounted to move around a rotary axis of a mast 3 in a direction to intersect the rotary axis by a geared motor, and an upper plate 63 which is mounted on the central opening part of the lower plate through a bearing and is connected with the lower plate through a blade holder 43 and a control arm 64 slantingly connected to the mast. A rotational surface of a lower blade 51 is tilted by the control arm in conjunction with the movement of the swash plate 61 in the direction to intersect the rotary axis of the mast. As a result, a moving direction of an aircraft 2 is controlled. The flight posture of the aircraft is controlled by interlocking rotations made by an upper rotor head 4 and a stabilizer 7.
