1. A model car assembly comprising:
- a chassis;
a first arm means having an inner end and an outer end, the outer end receiving ground engaging means;
a first pivotal mounting intermediate the inner and outer end of said first arm means for pivotally mounting said first arm means to said chassis;
second arm means having an inner end and an outer end, the outer end receiving ground engaging means, the inner end of said second arm means contactable with the inner end of said first arm means;
a second pivotal mounting intermediate the inner and outer end of said second arm means for pivotally mounting said second arm means to said chassis;
a drive motor;
a gear train coupling said motor to said first arm means to selectively move said first arm means about said first pivotal mounting causing the inner end thereof to move and simultaneously to cause the inner end of the second arm to move causing the respective arms and the respective ones of the ground engaging means to approach one another to cause said chassis to move upwardly.

11. A model car assembly comprising:
-
a chassis;
first set of arms having outer ends and inner ends, said arms receiving ground engaging means at the outer ends thereof;
a first pivotal mounting intermediate the outer and inner ends of said first set of arms for pivotally mounting said first set of arms to said chassis;
a second set of arms having outer and inner ends of said arms receiving ground engaging means at the outer ends thereof, and the inner ends of said second set of arms in sliding engagement with the inner ends of said first set of arms;
a second pivotal mounting intermediate the outer and inner ends of said second set of arms for pivotally mounting said second set of arms to said chassis;
a pivotal slip coupling for pivotally interconnecting the inner ends of said first set of arms and the inner ends of said second set of arms;
a drive motor;
a cam member engaging said first set of arms between the outer ends thereof and said first pivotal mounting;
a gear train coupled to said drive motor to drive said cam member to cause movement of said chassis upwardly and downwardly by causing pivotal movement of said first set of arms whereby the inner ends of said first set of arms cams the inner ends of said second set of arms upwardly causing an upward movement of said chassis.
