Patent ID: 7789340

Claim:
A flying model airplane comprising: a fuselage having a first wing and a second wing attached to and extending from opposite sides of the fuselage; wherein the fuselage is formed of a deformable material, the material being a polyfoam; a third wing disposed under the first wing and a fourth wing disposed under the second wing; wherein the fuselage provides a relatively flat bottom surface for landing on the ground; a first propulsion unit, having a first motor and a first propeller rotated by the first motor, mounted at the back of the first wing; a second propulsion unit, having a second motor and a second propeller rotated by the second motor, mounted at the back of the second wing; a tail having an elevator spaced from the first and second propellers by a distance; the elevator extends to a first side on one side of a rudder and to a second side of the opposite side of the rudder; and the projected circumference of the first propeller is overlapping the first side of the elevator; and the projected circumference of the second propeller is overlapping the second side of the elevator, as seen from above the airplane wherein the axis of rotation of each of the first and second propellers is angled in a downward direction, the first motor and the second motor are each mounted underneath the first and second wing, respectively; the first and third wings being connected by a first strut, and the second and fourth wings being connected by a second strut, and wherein the first propulsion unit is mounted between the fuselage and the first strut and the second propulsion unit is mounted between the fuselage and the second strut; the rudder and the elevator each coupled to the fuselage by a long, thin rod; a processor coupled to control the first and second motors, wherein the processor is operable to control a rotational speed difference between the first and second propellers to assist the airplane in making a turn; a radio receiver coupled to the processor; and a battery mounted in the fuselage and coupled to provide power to operate the radio receiver.
