Disclosed is a flying toy capable of moving by flapping of wings. The flying toy comprises a support structure; an actuation mechanism, for the wings, arranged on the support structure and comprising a crank drive rotated by a means providing the driving force; and two flexible wings arranged symmetrically with respect to the vertical plane of symmetry of the toy and connected, at the wing bases, to the actuation mechanism, the aforementioned wing bases being mounted oscillating about axes arranged on both sides of the vertical plane of symmetry of the toy. A controller receives a control signal indicating a left turn, increases the tension on the right wing and reduces it on the left wing and, for a right turn, the opposite action is performed.

1. A flying toy capable of moving by flapping of wings, the flying toy comprising: a support structure,an actuation mechanism arranged on the support structure and comprising a rotatable crank drive,two flexible wings each comprising a wing base, the two flexible wings being arranged symmetrically with respect to a vertical plane of symmetry of the toy and connected, at the wing bases, to the actuation mechanism, the wing bases being mounted oscillating about axes arranged on both sides of the vertical plane of symmetry of the toy, anda motor that, responsive to receiving a control signal indicating a left turn, increases a tension on the right wing while reducing a tension on the left wing thereby effecting a left turn, and that, responsive to receiving a control signal indicating a right turn, increases the tension on the left wing while reducing the tension on the right wing thereby effecting a right turn. 2. A toy according to claim 1, wherein posterior edges of a main airfoil of the wings are attached on a rudder configured to pull laterally on the edges, in a plane of the wings, so as to change the tension of the wings: a lateral traction on the posterior edge of the right wing increases the tension on the right wing and decreases the tension on the left wing,a lateral traction on the posterior edge of the left wing increases the tension on the left wing and decreases the tension on the right wing. 3. A toy according to claim 2, wherein the rudder is mounted pivoting around an axis perpendicular to the plane of the wings, the pivoting of the rudder causing a lateral traction on the posterior edges of the main airfoil of the wings. 4. A toy according to claim 2, wherein the rudder is mounted movable in translation in a direction parallel to the plane of the wings, a displacement of the rudder causing a lateral traction on the posterior edges of the main airfoil of the wings. 5. A toy according to claim 2, wherein a movement of the rudder is controlled via a radio-controlled motor. 6. A toy according to claim 2, wherein a return spring enables restoration of the rudder in a neutral position where no traction is exerted on the wings. 7. A toy according to claim 6, wherein: the movement of the rudder is controlled via a radio-controlled motor,the radio-controlled motor is provided with reduction ratio device,and wherein the spring is pretensioned in the neutral position, the arms of the spring being held apart by an element, the pre-tension enabling restoration of the rudder positively into the neutral position, compensating for the residual frictions of the reduction ratio device. 8. A toy according to claim 1, wherein the wings comprise spanwise wing beams connected to the wing bases, the spanwise beams being formed from a first part inserted into the wing bases and at the end of which is attached a rod, the latter being pivotally mounted, about its longitudinal axis, in the first part. 9. A toy according to claim 8, wherein the rods are tightly fitted and/or cemented in a sheath, the latter covering the rods so as to consolidate their base and decrease the fragility at this area. 10. A method for controlling a flying toy capable of moving by flapping of wings, the toy comprising: a support structure,an actuation mechanism arranged on the support structure and comprising a rotatable crank drive,two flexible wings each comprising a wing base, the two flexible wings being arranged symmetrically with respect to a vertical plane of symmetry of the toy and connected, at the wing bases, to the actuation mechanism, the wing bases being mounted oscillating about axes arranged on both sides of the vertical plane of symmetry of the toy,the method comprising: receiving a control signal,responsive to the control signal indicating a right turn, increasing the tension on the left wing while reducing a tension on the right wing, to effect a right turn, andresponsive to the control signal indicating a left turn, increasing the tension on the right wing while reducing the tension on the let wing, to effect a left turn. 11. A toy according to claim 1, further comprising a wheel defining an axis of rotation substantially parallel to the vertical plane, wherein the motor increases the tension on the right wing while reducing the tension on the left wing by rotating the wheel in a first direction, and increases the tension on the left wing while reducing the tension on the left wing by rotating the wheel in a second direction opposite the first direction. 12. A toy according to claim 11 wherein the wheel is a gear. 13. A flying toy capable of moving by flapping of wings, the flying toy comprising: a support structure,an actuation mechanism arranged on the support structure and comprising a rotatable crank drive,two flexible wings each comprising a wing base, the two flexible wings being arranged symmetrically with respect to a vertical plane of symmetry of the toy and connected, at the wing bases, to the actuation mechanism, the wing bases being mounted oscillating about axes arranged on both sides of the vertical plane of symmetry of the toy,means, responsive to a control signal indicating a right turn, for increasing the tension on the left wing while reducing a tension on the right wing, to effect a right turn, andmeans, responsive to the control signal indicating a left turn, for increasing the tension on the right wing while reducing the tension on the left wing, to effect a left turn.
