A vertical tail unit 16 formed of a short band-shaped wing made of a similar plastic material is mounted on an upper portion on the rear end side of the body unit 11 to which the horizontal tail unit 13 is mounted.
[0012]
The vertical tail section 16 includes a front vertical tail body section 16a fixed to the upper rear end portion side of the body section 11, and a rudder 16b rotatably attached to the rear side of the vertical tail body section 16a in the left-right direction. It is composed of Between the vertical tail main body 16a and the rudder 16b, a rectangular plate-shaped spring member 31 made of, for example, plastic or metal material and having a restoring force is attached and connected at two upper and lower locations. That is, the rudder 16b is normally positioned in the same direction at the rear side of the vertical tail main body 16a due to the restoring force of the spring member 31, and the turning mechanism 30 described later in detail applies a turning force to the left and right. When it is received, it bends left and right against the restoring force of the spring member 31.
[0013]
One end of the turning mechanism 30 is connected to a rudder rotation motor 26, a reduction gear train 27 driven by the rudder rotation motor 26, and a connecting portion 28 formed on the last gear of the gear train 27. It is connected with a connecting rod 29 and the like, the other end of which is connected to a connecting portion 32 formed on the rudder 16b. The rudder turning motor 26 is mounted substantially at the center of the body 11 with the output shaft directed horizontally to the body 11. A gear train 27 composed of a plurality of reduction gears is provided on the output shaft of the steering motor 26. A connection portion 28 is formed on the last gear of the gear train 27 so as to project outward from the center. The gear train 27 has a reduction ratio such that forward rotation and reverse rotation of the rudder rotation motor 26 are transmitted to the final stage gear, and the connecting portion 28 swings in the front-rear direction of the body portion 11. It is. The connecting rod 29 is made of, for example, an elongated metal rod having rigidity. One end of the connecting rod 29 is connected to the connecting portion 28 of the gear train 28, and the other end of the connecting rod 29 is connected to the rear vertical tail 16 along the body 11. It is extended and is connected to a connecting portion 32 formed to project from the surface of the rudder 16b. That is, the turning mechanism 30 is configured such that the forward rotation and the reverse rotation of the rudder rotation motor 26 are reduced via the gear train 27, and the connecting rod provided between the last gear of the gear train 27 and the rudder 16 b is provided. 29 is converted into a pushing / pulling force along the longitudinal direction of the body 11, and the rudder 16 b rotates left and right against the restoring force of the spring member 31 by the pushing / pulling force.
[0014]
The transmitter 17 includes a control stick unit 19 for performing a remote operation, a control signal generation circuit 20 for generating a control signal corresponding to the operation of the control stick unit 19, and a control signal generated by the control signal generation circuit 20. , For example, a transmission circuit 21 for transmitting from the antenna 22 by radio waves. The receiving circuit 18 is mounted in the body 11, and receives a control signal transmitted from the transmitter 17 via an antenna 23 and a receiving circuit 24 based on the control signal received by the receiving circuit 24. And a control circuit 25 for controlling the operation of the propeller driving motor 15 or the rudder turning motor 26.
[0015]
In the airplane toy 10 having the above-described configuration, in order to remotely control the vehicle, the control signal is transmitted by operating the control stick 19 of the transmitter 17, and the control signal is received by the receiver 18 mounted on the body 11 and driven by the propeller. By controlling the motor 15 for driving, the propeller 14 can be driven to fly in the air. Next, when making a right or left turn during a flight, the control stick unit 19 of the transmitter 17 is similarly operated to receive a right or left turn control signal at the receiver 18, and a steering motor 26 is turned at the control circuit 25. Is controlled and the rudder turning motor 26 of the turning mechanism 30 is decelerated in the forward or reverse operation via the gear train 27 in accordance with the control signal, and the final stage gear of the gear train 27 and the rudder 16 b Is converted into a pushing / pulling force along the longitudinal direction of the body portion 11, and the rudder 16b rotates right or left against the restoring force of the spring member 31 by the pushing / pulling force. I do. Due to the right or left rotation of the rudder 16b, the airplane toy 10 in flight turns right or left. Subsequently, when the right or left turning is stopped, when the driving of the turning motor 26 of the turning mechanism 30 is stopped, the pushing / pulling force disappears, and the restoring force of the spring member 31 returns the rudder 16b to the original vertical position. Fly straight. In the airplane toy 10, the turning force of the rudder turning motor 26 is converted into the pushing and pulling force of the connecting rod 29 via the gear train 27, and the pushing and pulling force causes the rudder 16b to resist the restoring force of the spring member 31. Since the turning mechanism 30 is turned to the left and right, the structure of the turning mechanism 30 is simplified, a small-sized rudder turning motor 26 can be used, the weight can be reduced, and the cost can be reduced. Further, since the restoring force of the spring member 31 is used, a special mechanism for returning the rudder 16b to the original position is not required, and the control is simplified.
