Tri-Motor Toy Aircraft

Abstract

A remote controlled tri-motor toy aircraft is provided. The tri-motor toy aircraft has two wing propellers and a tail propeller. Each propeller is controlled by a separate motor. The wing propellers provide thrust on the opposite side of the center of gravity of the toy aircraft to the thrust provided by the tail propeller, thus allowing the flight direction of the toy aircraft to be controlled by the relative thrusts of the three motors.

We claim: 
     
         1 . A remote controlled tri-motor toy aircraft having a center of gravity, the tri-motor toy aircraft comprising:
 a fuselage having a tail;   a left wing attached to a left side of the fuselage;   a right wing attached to a right side of the fuselage;   a left propeller disposed on the left wing, the left propeller being driven by a left motor so as to generate a left thrust;   a right propeller disposed on the right wing, the right propeller being driven by a right motor so as to generate a right thrust; and   a tail propeller disposed on the tail, the tail propeller being driven by a tail motor so as to generate a tail thrust;   wherein the left propeller and the right propeller are vertically displaced from the center of gravity in a first direction and the tail propeller is vertically displaced from the center of gravity of the toy aircraft in a second direction, the second direction being opposite to the first direction, the right motor, the left motor and the tail motor each being independently controlled by a controller remote from the toy aircraft such that controlling the left thrust, the right thrust and the tail thrust acts to control flight direction of the toy aircraft.   
     
     
         2 . The tri-motor toy aircraft of  claim 1 , wherein the left propeller and the right propeller are below the center of gravity and the tail propeller is above the center of gravity. 
     
     
         3 . The tri-motor toy aircraft of  claim 1 , wherein the left propeller and the right propeller are above the center of gravity and the tail propeller is below the center of gravity. 
     
     
         4 . The tri-motor toy aircraft of  claim 1 , wherein each of the left thrust, the right thrust and the tail thrust is independently selected from a forward thrust and a reverse thrust. 
     
     
         5 . The tri-motor toy aircraft of  claim 1 , wherein each of the left thrust, the right thrust and the tail thrust is a forward thrust.
