Radio controlled toy model

Abstract

A radio controlled single string kite allows for the performance of controlled stunts that are generally only found in two string kites. A remote control includes R/C electronics, a string spool, a spool control and right and left turning controls. The kite includes a wing string and an R/C receiver (RX) unit connected to the bottom of the downwardly extending center wing (or keel). The wing string connects the main wing to the keep via the R/C receiver (RX) unit. The R/C receiver (RX) unit includes all R/C electronics and gearing to control the position of the center wing with respect to the main wing through the selective movement of the keel through the gearing. The R/C receiver RX unit remains connected to the remote control (TX) via the string on the string spool.

       6 . The radio controlled model of  claim 1 , further comprising at least one stopper positioned on the link line and configured to limit a range of motion of said link line with respect to the radio control receiver unit. 
   
   
       7 . The radio controlled model of  claim 2 , wherein the at least one spool control comprises a spool link lever lock for selectively locking or the releasing the spool. 
   
   
       8 . The radio controlled model of  claim 2 , wherein the at least one spool control comprises a trigger for controlling a speed of said spool during let out of the string. 
   
   
       9 . The radio controlled model of  claim 2 , wherein the at least one spool control comprises a rewind handle for rewinding the string onto the spool. 
   
   
       10 . The radio controlled model of  claim 2 , wherein the at least one action control comprises at least one control lever having a left and right control position corresponding to left and right radio signals to be sent to the radio control receiver unit. 
   
   
       11 . A radio controlled model comprising:
 a toy model having a main wing supported by frame members, a central downward extending wing and a link line connecting opposing frame members of the main wings; and   a radio control steering mechanism connected to a bottom of the central downward extending wing and having a gear mechanism connected to the link line, said steering mechanism selectively moving the position of the central wing with respect to the main wing along the link line;   a radio control transmitter unit connected to the radio control steering mechanism by a cord and configured to provide radio control signals to the steering mechanism and thereby selectively move the steering mechanism and center wing along the link line.   
   
   
       12 . The radio controlled model of  claim 11 , wherein said radio control steering mechanism comprises:
 a motor connected to the gear mechanism;   a receiver printed circuit board configured to translate received radio control signals into electrical signals for causing the motor to rotate in one of a clockwise or counter clockwise direction; and   a battery power supply source for providing power to the radio control steering mechanism.   
   
   
       13 . The radio controlled model of  claim 11 , wherein the radio control transmitter comprises:
 a cord spool ( 20 ,  220 ) with cord ( 22 ,  222 ) wound thereon and having an end connected to the radio control steering mechanism ( 110 ,  310 );   at least one spool control; and   at least one action control lever ( 16 ,  18 ,  216 ).   
   
   
       14 . The radio controlled model of  claim 13 , wherein the at least one spool control comprises a spool link lever lock for selectively locking or the releasing the spool. 
   
   
       15 . The radio controlled model of  claim 13 , wherein the at least one spool control comprises a trigger for controlling a speed of said spool during let out of the string. 
   
   
       16 . The radio controlled model of  claim 13 , wherein the at least one spool control comprises a rewind handle for rewinding the string onto the spool. 
   
   
       17 . The radio controlled model of  claim 13 , wherein the link line comprises a string. 
   
   
       18 . The radio controlled model of  claim 13 , further comprising at least one stopper positioned on the link line and configured to limit a range of motion of said link line with respect to the radio control steering mechanism.
