A remote electro-aeroplane is mainly characterized in that the turn rudder surface is jointed to the tail stabilizer by a plastic film on their upper faces with a separation of the elastic foaming material from the plastic film on their lower faces at their joint, wherein two flexible cables or nylon wires are connected to the left and the right racks arranged on the left and the right turn rudder surfaces with their one end respectively and to the servo means within the remote receiving device with their another end, and the restoration mechanisms are provided beneath the left and the right turn rudder surfaces respectively. Based on this structure, the aeroplane has the advantages of easy control with smooth fly in case of making a turn, and is particularly suitable for the primary player.

1. A remote-controlled electro-aeroplane, comprising: a body; a wing attached to said body; a propeller connected to said body; a remote receiving device attached to said body for receiving a remotely transmitted signal, and including a servo that controls a flight of the electro-aeroplane in response to the remotely transmitted signal; and V-type empennage attached to said body, including: a left tail stabilizer and a right tail stabilizer that together form a V-shape; a left turn rudder connected to said left tail stabilizer, and a right turn rudder connected to said right tail stabilizer; a layer of plastic film attached on an upper surface of said left tail stabilizer, an upper surface of said right tail stabilizer, an upper surface of said left turn rudder and an upper surface of said right turn rudder, said plastic film jointing said left tail stabilizer to said left turn rudder, and jointing said right tail stabilizer to said right turn rudder; left rack disposed on said left turn rudder and a right rack disposed on said right turn rudder; a left flexible cable having one end connected to said left rack and another end connected to said servo, and a right flexible cable having one end connected to said right rack and another end connected to said servo, said servo being activatable to pull said left flexible cable thereby causing said left turn rudder to pivot in a first direction relative to said left tail stabilizer, said servo further being activatable to pull said right flexible cable thereby causing said right turn rudder to pivot in the first direction relative to said right tail stabilizer; and a restoration mechanism attached to said left turn rudder and to said right turn rudder, said restoration mechanism causing said left turn rudder and said right turn rudder to pivot in a second direction that is opposite to the first direction when said servo is not activated. 2. The remote electro-aeroplane of claim 1, wherein said restoration mechanism comprises left and right elastic bands, said left elastic band having one end fixed on a lower face of said left tail stabilizer and having another end fixed on a lower face of said left turn rudder, said right elastic band having one end fixed on a lower face of said right tail stabilizer and having another end fixed on a lower face of said right turn rudder. 3. The remote electro-aeroplane of claim 1, wherein said restoration mechanism is a single rubber band having one end connected to a further left rack disposed on a lower surface of said left turn rudder, another end connected to a further right rack disposed on a lower surface of said right turn rudder, and an intermediate portion attached to a tail rack fixed between a tail pole and a joint of said left and right tail stabilizers. 4. The remote electro-aeroplane of claim 1, wherein said servo comprises two electromagnets. 5. The remote electro-aeroplane of claim 1, wherein said flexible cable comprises a nylon wire. 6. The remote electro-aeroplane of claim 1, wherein an edge face of said left tail stabilizer is abuttable against an edge face of said left turn rudder to act as a pivot stop, and an edge face of said right tail stabilizer is abuttable against an edge face of said right turn rudder to act as a pivot stop. 7. The remote electro-aeroplane of claim 1, wherein said left tail stabilizer, said right tail stabilizer, said left turn rudder and said right turn rudder are formed from an elastic foam.
