To further stabilize the flight operation of an R/C helicopter, thereby improving operability, based on the finding that a position of appearance of gyro precession is different from the conventional R/C helicopter. A rotor head of a coaxial counter-rotating R/C helicopter is configured so that upper and lower main rotors MR are provided, in response to gyro precession of the main rotors as an output to an operation input from the swash plates appears within a range smaller than 90°, mounting positions of the upper and lower main rotors are provided to become an angle smaller than 90° around the main masts and with respect to the input positions of each of cyclic controls to upper and lower main rotors using the upper and lower swash plates, and the upper and lower main rotors and the upper and lower swash plates are connected via a link mechanism.
