Abstract: A hopping model car includes a body, a pair of vertically adjustable rear wheels mounted near the rear of the body, a pair of vertically movable front wheels mounted near the front of the body, and an actuator connected to the front wheels. The car is balanced to have a center of gravity slightly in front of a rear axle. To use, the rear wheels are adjusted downwardly to raise the rear end of the car. The front wheels are quickly extended downwardly to propel the front end of the car into the air. The car is balanced for hopping with less power consumption and a less powerful actuator, and for causing the front end to fall realistically slowly.

Abstract: A radio controlled scale model of a low rider vehicle including a chassis and first and second axels supported on the chassis, a lift assembly includes the chassis being provided with guide structure for maintaining the transverse orientation of the front axle while allowing movement of the axle relative to the chassis within a plane perpendicular to the central longitudinal axis of the chassis. The lifting action is accomplished by a solenoid whose push rod presses on a pivotable "L" shaped lever arm which in turn presses on the front axle causing the chassis and attached vehicle body to rise when activated and fall when released simulating a low rider "hop". The power supply located in the trunk portion of the vehicle acts as a counter balance so that the front wheels lift easily.
