22. A radio-controlled car, comprising:
-
a chassis having a front portion, a middle portion and a rear portion;
a rear wheel drive assembly housed in the rear portion of the chassis;
a motor housed in the middle portion of the chassis, the motor being adapted to impart motion to the rear wheel drive assembly;
a drive shaft operatively connected to the motor, the drive shaft extending from the rear portion of the chassis to the front portion of the chassis;
a modular front-wheel drive assembly adapted to be inserted into the front portion of the chassis, whereby insertion of the modular front-wheel drive assembly operatively engages the front-wheel drive assembly with the drive shaft to convert the radio-controlled car from a two-wheel drive configuration to a four-wheel drive configuration. - View Dependent Claims (23, 24, 25, 26, 27)
