       2 . The vehicle according to  claim 1 , further comprising a source of electrical energy.  
   
   
       3 . The vehicle according to  claim 2 , further comprising a controller for selectively controlling said means for imparting a pivotal movement, said means for moving said first set of wheels, and said means for moving said second set of wheels.  
   
   
       4 . The vehicle according to  claim 3 , wherein said controller is a wireless remote transmitter.  
   
   
       5 . The vehicle according to  claim 1 , wherein said pivoting member is a yoke.  
   
   
       6 . The vehicle according to  claim 5 , wherein the yoke includes a pair of spaced apart arms.  
   
   
       7 . The vehicle according to  claim 6 , wherein said first set of ground engaging wheels are mounted to respected ones of the arms of the yoke.  
   
   
       8 . The vehicle according to  claim 7 , further comprising a cam surface disposed on the yoke.  
   
   
       9 . The vehicle according to  claim 2 , wherein said means for imparting a pivotal movement includes a first electric drive motor.  
   
   
       10 . The vehicle according to  claim 9 , wherein said pivoting member is a yoke having a cam surface disposed thereon, the first electric drive motor operably engaging the cam surface of the yoke to cause pivotal movement of the yoke.  
   
   
       11 . The vehicle according to  claim 2 , wherein said means for moving said first set of wheels includes a second electric drive motor.  
   
   
       12 . The vehicle according to  claim 2 , wherein said means for moving said second set of wheels includes a third electric drive motor.  
   
   
       13 . A remote controlled model vehicle comprising: 
 a chassis;    a pivoting member pivotally mounted to said chassis;    a first set of ground engaging wheels attached to said pivoting member;    means for imparting a pivotal movement of said pivoting member in respect of said chassis to cause a raising and lowering of at least a portion of said chassis;    means for rotating said first set of wheels about respective vertical axes to effect a steering of the vehicle;    a second set of ground engaging wheels mounted to said chassis in spaced relation from said first set of wheels;    means for rotating said second set of wheels about a respective horizontal axis to cause a driving motion of the vehicle; and    a controller for selectively controlling said means for imparting a pivotal movement, said means for rotating said first set of wheels, and said means for rotating said second set of wheels.    
   
   
       14 . The vehicle according to  claim 13 , wherein said controller is a wireless transmitter.  
   
   
       15 . The vehicle according to  claim 13 , further comprising a source of electrical energy.  
   
   
       16 . The vehicle according to  claim 13 , wherein said pivoting member is a yoke including a pair of spaced apart arms and a cam surface, wherein said first set of ground engaging wheels are mounted to respected ones of the arms of the yoke.  
   
   
       17 . The vehicle according to  claim 16 , wherein said means for imparting a pivotal movement includes a first electric drive motor operably engaging the cam surface of the yoke to cause pivotal movement of the yoke.  
   
   
       18 . The vehicle according to  claim 13 , wherein said means for rotating said first set of wheels includes a second electric drive motor.  
   
   
       19 . The vehicle according to  claim 13 , wherein said means for rotating said second set of wheels includes a third electric drive motor.  
   
   
       20 . A remote controlled model vehicle comprising: 
 a chassis;    a yoke pivotally mounted to said chassis and having a pair of spaced apart arms and a cross-piece interconnecting the arms;    at least one ground engaging wheel attached to the arms of said yoke;    a first electric drive motor for imparting a pivotal movement of said yoke in respect of said chassis to cause a raising and lowering of at least a portion of said chassis;    a second electric drive motor for rotating said at least one ground engaging wheel about a vertical axis to effect a steering of the vehicle;    at least one ground engaging wheel mounted to said chassis in spaced relation from said at least one ground engaging wheel attached to the arms of said yoke, said at least one ground engaging wheel mounted to said chassis including a third electric drive motor to cause a rotation thereof about a horizontal axis to cause a driving motion of the vehicle;    a source of electrical energy for said electric drive motors; and    a remote transmitter for transmitting signals to effect selective energization of said electric drive motors.
