The trial production of new concept rotorcraft was carried for the aiming at a weather survey. The three blades with movable wing vane and driving force are connected fixed pitch angle. The direction of flight is controllable using at least one movable wing vane which is synchronizing with rotation of the aircraft by monitoring the direction with a geomagnetism sensor. The deflection angle of the direction of flight and control direction for the prototype was around 100 degree, due to the gyroscopic precession, delay time of the monitoring R/C receiver and mechanical response of the servo motor. The flight posture should be controlled based on the deflection angle to avoid the precession of the aircraft.
