Abstract
Abstract A radio control racing car having a resilient suspension system which is adjustable is provided. The wheels of the car are permitted to flex substantially independently of each other with a positive control provided for the amount of flexibility of each wheel. A motor mount is provided which permits the motor to be fixedly clamped into its desired operative position.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
153 words
A racing car comprising a chassis having a main body portion, a front segment and a rear segment, said car having front wheels and rear wheels the front segment of the chassis supporting the front wheels of the racing car, the rear segment of the chassis supporting the rear wheels of said racing car, means on said chassis for resiliently mounting the front wheels of said racing car, said means including the least said front chassis segment being composed of highly flexible resilient material and means for varying the flexibility of said resilient means for each of the front wheels of the racing car, said means for varying the flexibility of each of the front wheels of the racing car including slots within said front chassis segment and locking means in said slots to vary the effective length of said slots thereby varying the flexibility of each of said front wheels substantially independently.
Claim 2
Dependent Claim
153 words
A racing car comprising a chassis having a main body portion, a front segment and a rear segment, said car having front wheels and rear wheels the front segment of the chassis supporting the front wheels of the racing car, the rear segment of the chassis supporting the rear wheels of said racing car, means on said chassis for resiliently mounting the front wheels of said racing car, said means including the least said front chassis segment being composed of highly flexible resilient material and means for varying the flexibility of said resilient means for each of the front wheels of the racing car, said means for varying the flexibility of each of the front wheels of the racing car including slots within said front chassis segment and locking means in said slots to vary the effective length of said slots thereby varying the flexibility of each of said front wheels substantially independently.
Claim 3
Dependent Claim
76 words
A racing car as set forth in claim 1 including means for resiliently mounting the rear wheels of said car, said rear chassis segment being composed of highly flexible resilient material, slots in said rear chassis segment to substantially independently flexibly mount the rear wheels of said car, and locking means cooperating with said slots to permit varying the effective length of said slots and thereby independently varying the flexibility for each of said rear wheels.
Claim 4
Dependent Claim
45 words
A racing car set forth in claim 1 including a motor mount secured to said rear chassis segment, said motor mount including an axle housing formed integrally therewith, said motor mount having positive clamping means associated therewith for locking an engine to said motor mount.
Claim 5
Dependent Claim
116 words
A racing car having front and rear wheels including a chassis having a main body portion, a rear chassis segment, and a front chassis segment, at least said front and said rear chassis segments being composed of highly flexible resilient material, means in said front chassis segment for substantially independently resiliently supporting each of the front wheels of the racing car, means for varying the amount of resiliency for each of the front wheels of the racing car, said means including slots in said front chassis segment, and locking means in each of said slots for varying the effective length of each slot to thereby vary the flexibility of each of the front wheels substantially independently.
Claim 6
Dependent Claim
116 words
A racing car having front and rear wheels including a chassis having a main body portion, a rear chassis segment, and a front chassis segment, at least said front and said rear chassis segments being composed of highly flexible resilient material, means in said front chassis segment for substantially independently resiliently supporting each of the front wheels of the racing car, means for varying the amount of resiliency for each of the front wheels of the racing car, said means including slots in said front chassis segment, and locking means in each of said slots for varying the effective length of each slot to thereby vary the flexibility of each of the front wheels substantially independently.
Claim 7
Dependent Claim
97 words
A racing car as set forth in claim 4 including a motor mount secured to and supported by the rear chassis segment, said motor mount having a rear axle housing formed integral therewith, said motor mount including clamping means for positively locking an engine into its desired operative position, slots in said rear chassis segment for permitting the rear wheels of the racing car to be substantially independently resiliently mounted, said slots being on opposite sides of said motor mount, and locking means in the slots to vary the effective length of each of said slots independently.
Claim 8
Dependent Claim
38 words
A racing car as set forth in claim 4 wherein said chassis main body is composed of a relatively rigid high strength metal and said front and rear chassis segments are composed of highly flexible resilient plastic material.
Claim 9
Dependent Claim
130 words
A racing car having front and rear wheels and a chassis for supporting said wheels including a motor mount secured to said chassis, said motor mount having a bottom wall and side walls extending upwardly therefrom defining a cavity for receiving an engine, said bottom wall being adapted to support an engine, said motor mount including spaced intermediate horizontal planar surfaces, said motor mount including spaced top horizontal wall surfaces spaced from said horizontal planar surfaces, clamping means adapted to be secured to said top wall surfaces for securing flanges of the engine between said clamping means and said intermediate planar surfaces, said motor mount having a rear axle housing formed integrally therwith, said rear axle housing supporting the rear axle which supports the rear wheels of said racing car.
Claim 10
Dependent Claim
130 words
A racing car having front and rear wheels and a chassis for supporting said wheels including a motor mount secured to said chassis, said motor mount having a bottom wall and side walls extending upwardly therefrom defining a cavity for receiving an engine, said bottom wall being adapted to support an engine, said motor mount including spaced intermediate horizontal planar surfaces, said motor mount including spaced top horizontal wall surfaces spaced from said horizontal planar surfaces, clamping means adapted to be secured to said top wall surfaces for securing flanges of the engine between said clamping means and said intermediate planar surfaces, said motor mount having a rear axle housing formed integrally therwith, said rear axle housing supporting the rear axle which supports the rear wheels of said racing car.
Claim 11
Dependent Claim
30 words
A racing car as set forth in claim 7 wherein one of said top horizontal planar wall surfaces is formed by cutting away a portion of said rear axle housing.
Claim 12
Dependent Claim
49 words
A racing car as set forth in claim 7 wherein the side walls of said motor mount have C-shaped grooves formed therein to permit the cavity provided by the motor mount to be readily enlarged so that the motor mount may be adapted to receive engines of increased size.
