WHAT IS CLAIMED IS:
1. A toy aiφlane assembly, comprising:
a fuselage having first and second main wings and a tail;
first and second motors connected to said first and second main wings,
respectively;
first and second propellers connected to and driven by said first and second motors, respectively;
a battery housed in said fuselage;
a circuit board housed in said fuselage and connected to said battery; and a microprocessor housed in said fuselage and connected to said circuit
board for controlling said first and second motors to control flight of
the toy aiφlane assembly.

2. A toy airplane assembly according to claim 1, wherein
first and second rear wings are attached to said fuselage.

3. A toy aiφlane assembly according to claim 2, wherein
a rear-most point of each of said first and second main wings is proximal a forward-most point of each of said first and second rear wings.

4. A toy aiφlane assembly according to claim 3, wherein
said rear-most points are rearward of said forward-most points.

5. A toy aiφlane assembly according to claim 1, wherein
said battery is rechargeable.

6. A toy aiφlane assembly according to claim 1, wherein
said fuselage is foam.

7. A toy aiφlane assembly according to claim 1, wherein
said fuselage is selected from the group consisting of EPS and EPP foam.

8. A toy aiφlane assembly according to claim 1, wherein
a transmitter transmits a signal corresponding to a flight maneuver; and
a radio receiver housed in said fuselage and connected to said circuit board receives said transmitter signal and sends said signal to said
microprocessor.

9. A toy aiφlane assembly according to claim 1, wherein
a first switch comiected to said microprocessor adjusts control of said first and second motors by said microprocessor.

10. A toy aiφlane assembly according to claim 5, wherein
a docking station recharges said battery.

11. A toy aiφlane assembly according to claim 10, wherein
a second switch connected to said docking station controls a recharge level of said battery.

12. A toy aiφlane assembly according to claim 1 , wherein
said fuselage, said first and second main wings, and said first and second
rear wings are integrally connected.

13. A toy airplane assembly according to claim 8, wherein
an antenna is connected to said receiver and housed in said fuselage to
facilitate reception of said transmitter signal by said receiver.

14. A toy aiφlane assembly according to claim 1, wherein
said fuselage has a vent for cooling said battery with air during flight.

15. A toy airplane assembly according to claim 10, wherein
a first switch connected to said microprocessor adjusts control of said first and second motors by said microprocessor; and
a tab on said docking station engages said first switch when said toy
aiφlane is attached to said docking station and moves said first switch to a battery charging position.

16. A toy airplane assembly according to claim 1 , wherein
first and second gears are connected between said first motor and said first propeller and between second motor and second propeller.

17. A toy aiφlane assembly according to claim 16, wherein
said first and second gears have a motor to propeller ratio of approximately 2.66 to 1.

18. A method of flying a toy airplane, comprising:
(a) supplying first and second currents from a microprocessor stored in a fuselage of the toy airplane to first and second motors, respectively, the first and second currents corresponding to a maneuver to be performed by the toy airplane;
(b) powering the first and second motors in response to the received first and second currents, respectively;
(c) driving first and second propellers with the first and second motors,
respectively, in response to the first and second currents causing the
toy airplane to perform the maneuver; and
(d) repeating steps (a) through (c) to control flight of the toy aiφlane.

19. A method of flying a toy aiφlane according to claim 18, further comprising preprogramming the microprocessor with a flight pattern having at least one maneuver, and
executing the preprogrammed flight pattern during flight of the toy
aiφlane to repeatedly generate ihc first and second currents to control flight of the toy aiφlane.

20. A method of flying a toy airplane accoiding to claim 19, wherein
preprogramming the microprocessor with a flight pattern having at least one maneuver comprises preprogramming the microprocessor with at least two flight patterns; and
selecting a flight pattern to be executed.

21. A method of flying a toy aiφlane accoiding to claim 18, further comprising
sending a signal from a transmitter to the microprocessor, the signal
corresponding to a maneuver to be performed by the toy aiφlane;
decoding the signal with the microprocessor; and
supplying the first and second currents in response to the decoded signal.

22. A method of flying a toy airplane accoiding to claim 21, further comprising
supplying the first and second currents when the toy aiφlane has not
received the signal from the transmitter for a predetermined amount of time.

23. A method of flying a toy airplane accoiding to claim 22, wherein
supplying the first and second currents comprises supplying first and
second currents to land the toy airplane.

24. A method of flying a toy airplane according to claim 21, further comprising
supplying the first and second currents when the toy aiφlane has reached a predetermined distance from the transmitter.

25. A method of flying a toy aiφlane according to claim 22, wherein
supplying the first and second currents comprises supplying the first and
second currents to land the toy airplane.

26. A method of flying a toy airplane according to claim 18, further comprising
selecting a control level with a switch on the toy aiφlane, wherein said
control level controls the amount of the first and second currents
supplied to the first and second motors.
