A radio controlled toy vehicle having a frame comprised of a first frame portion and a transmission assembly portion. The transmission assembly portion having two wheels connected to an axle to support the transmission assembly and an electric motor and gear system for moving the toy vehicle in a forward or reverse direction. The toy vehicle has a gear box with an electric motor a first and second rotatable cam. A rod connected to the transmission assembly and rotatably mounted on a pin and engaging a rod from on of the first rotatable cam to act as a cam follower moving the rod in an up and down direction when the first rotatable cam rotates thereby extending the transmission assembly. A second rod connected to a third wheel and engaging a rod located on the second rotatable cam distal to the wheel and acting as a cam follower wherein the rod moves in an up and down direction when the second rotatable cam rotates, thereby extending the wheel attached at the distal end of the rod. These motions cam simulate “lowrider” type motions on specially adapted vehicles.

1. A radio controlled toy vehicle, comprising:a frame having a longitudinal axes and comprised of a first frame portion and a transmission assembly portion;said transmission assembly portion having first and second wheels connected to a rear axle to support said transmission assembly; said transmission assembly further having a first electric motor and a gear system for transferring rotational output of said first electric motor to said rear axle thereby rotating said first and second wheels in a predetermined direction;a gear box having a system of gear-wheels that accept a rotational output of a second electric motor and transfers said rotational output to a first rotatable cam when said second electric motor rotates in a clockwise direction and transfers said rotational output to a second rotatable cam when said second electric motor rotates in a counter-clockwise direction; said first rotatable cam having a first rod positioned off center to said first rotatable cam and extending out generally perpendicular to a surface of said first rotatable cam; said second rotatable cam having a second rod positioned off center to said second rotatable cam and extending out generally perpendicular to a surface of said second rotatable cam;a third rod connected to the transmission assembly and rotationally mounted on a first pin on said first frame portion thereby enabling said third rod to move rotationally with respect to said first frame portion; said third rod dimensioned to engage said second rod as a follower so that the rotation of said second rotatable cam which moves said second rod around a circular path causes said third rod to move up and down in response to the position of said second rod;a fourth rod having a third wheel mounted on an end; said fourth rod being rotationally mounted on a second pin on said first frame portion thereby enabling said fourth rod to move rotationally with respect to said first frame portion; said fourth rod dimensioned to engage said first rod on an end distal with respect to said third wheel as a follower so that the rotation of said first rotatable cam which moves said first rod around a circular path causes said fourth rod to move up and down in response to the position of said first rod;a fifth rod having a fourth wheel mounted on an end; said fifth rod being rotationally mounted on a third pin on said first frame portion thereby enabling said fifth rod to move rotationally with respect to said first frame portion;a receiver for receiving radio signals;an electrical power source electrically connected to said receiver; said receiver being electrically connected to electrical power inputs of said first and second electric motors and operable for selectively supplying electrical power to said first and second electric motors in response to receiving a predetermined respective radio signal; andwherein, said vehicle may be moved by said transmission assembly in a forward or reverse direction relative to said longitudinal axes in response to a respective predetermined radio signal; andwherein said third wheel may be selectively extended to engage a surface by the upward movement of said third rod and thereby cause said first frame portion to move in a direction away from said surface; andwherein said transmission assembly may be selectively extended to engage said surface by the upward movement of said fourth rod and thereby cause said first frame portion to move in a direction away from said surface. 2. The radio controlled toy vehicle as claimed in claim 1, further comprising a means for removably attaching a plastic shell for changing the appearance of said vehicle. 3. The radio controlled toy vehicle as claimed in claim 1, wherein said receiver is a four channel radio receiver. 4. The radio controlled toy vehicle as claimed in claim 2, wherein said receiver is a four channel radio receiver. 5. A radio controlled toy vehicle, comprising:a frame having a longitudinal axes and comprised of a fi rst frame portion and a rear assembly portion;said rear assembly portion having first and second wheels connected to an axle to support said rear assembly;a gear box having a system of gear-wheels that accept a rotational output of a first electric motor and transfers said rotational output to a first rotatable cam when said first electric motor rotates in a clockwise direction and transfers said rotational output to a second rotatable cam when said first electric motor rotates in a counter-clockwise direction; said first rotatable cam having a first rod positioned off center to said first rotatable cam and extending out generally perpendicular to a surface of said first cam; said second rotatable cam having a second rod positioned off center to said second rotatable cam and extending out generally perpendicular to a surface of said second cam;a third rod connected to the rear assembly and rotationally mounted on a first pin on said first frame portion thereby enabling said third rod to move rotationally with respect to said first frame portion; said third rod dimensioned to engage said second rod as a cam follower so that the rotation of said second rotatable cam which moves said second rod around a circular path causes said third rod to move up and down in response to the position of said second rod;a fourth rod having a third wheel mounted on an end; said fourth rod being rotationally mounted on a second pin on said first frame portion thereby enabling said fourth rod to move rotationally with respect to said first frame portion; said fourth rod dimensioned to engage said first rod on an end distal with respect to said third wheel as a cam follower so that the rotation of said first rotatable cam which moves said first rod around a circular path causes said fourth rod to move up and down in response to the position of said first rod;a fifth rod having a fourth wheel mounted on an end; said fifth rod being rotationally mounted on a third pin on said first frame portion thereby enabling said fifth rod to move rotationally with respect to said first frame portion;a receiver for receiving radio signals;an electrical power source electrically connected to said receiver; said receiver being electrically connected to electrical power inputs of said first electric motor and operable for selectively supplying electrical power to said first electric motor in response to receiving a predetermined respective radio signal;wherein said third wheel may selectively extended to engage a surface by the upward movement of said third rod and thereby cause said first frame portion to move in a direction away from said surface; andwherein said rear assembly may be selectively extended to engage said surface by the upward movement of said fourth rod and thereby cause said first frame portion to move in a direction away from said surface. 6. The radio controlled toy vehicle as claimed in claim 5, further comprising a means for removably attaching a plastic shell for changing the appearance of said vehicle. 7. The radio controlled toy vehicle as claimed in claim 5, wherein said receiver is a two channel radio receiver. 8. The radio controlled toy vehicle as claimed in claim 6, wherein said receiver is a two channel radio receiver.
