As described above, the helicopter toy 100 sets balancing device 180 on fuselage 110, and can be by operation signal certainly Rising, decline are operated by ground, keep specified altitude, advance, retrogressing, convolution etc., can indoors wait in windless condition space and carry out Stable flight, and relatively easily carry out manipulation operations.

But the helicopter toy 100 is usually made to small-size light-weight, cross-ventilation etc. slightly disturbs, and fuselage 110 will Back and forth or left and right is swung.

For swing, if if manipulation operations skilled person, can by the control operation advancing or retreat come into The reparation operation of normal flight must be reverted to by exercising, and still, if swinging, will can not carry out reparation operation, it is difficult into Row prevents the control for falling, falling.

But the helicopter toy 100 involved by present embodiment, as described above, also having while possessing stabilizer 170 Standby balancing device 180.Therefore, under the interference of turbulent flow etc., the normal condition shown in 110 A from Fig. 8 of fuselage is changed into the B of Fig. 8 During shown heeling condition, the supporting point of the balancing pole 197 of the top on the plumb line of 110 center of gravity of fuselage can be from plumb line Upper offset.Therefore, fuselage 110 is tilted, it is necessary to have a kind of power by both ends have bulge 199 balancing pole 197 from It is mobile beside direction on the position of centre of gravity of fuselage 110.

Therefore, the weight of balancing pole 197 becomes a kind of resistance relative to by 110 inclined external force of fuselage, thus Reduce the gradient of fuselage 110.

In addition, as shown in the B of Fig. 8, fuselage 110 tilts accidentally under external disturbance, in the work of balancing device 180 Under, the normal condition shown in the A of Fig. 8 can be reverted to quickly.

That is, after fuselage 110 is tilted to side, stabilizer 170 can keep the rotation in horizontal plane under the action of rotatory inertia Turn, therefore, the upper rotor first 155 being coupled by connecting shaft 179 with stabilizer first 171 can tilt, the rotation of upper rotor axis 153 Turn often to make the rotation of 180 degree, the inclination of the upper rotor first 155 is changing to anti-obliquity.

Therefore, the elevation angle as 157 inclination angle of upper rotor blade, the right side in the B of inclined side, that is, Fig. 8 become larger；In phase Left side in the B of anti-side, that is, Fig. 8 diminishes, and lifting force F1 significantly occurs in inclined side caused by upper rotor 151, such as schemes The lifting force F1 ' towards oblique upper just occurs shown in 8 B so that restore and tilt.
