Half Life 2 Charger

The jalopy of Half Life 2. Features drive, return to center steering and suspensions.


I wanted for a while to build a RC car which was powerful, fun and reliable. I have started to build a 4×4 transmission on a little car like the Fiat Panda 4×4 but because of the friction of the drive-train, the car was not really powerful. I decided to create a propulsion car with the return to center steering and based on the Lancia Montecarlo but again it was a fail because of the design. The scale was too small to manage enough detail, consequently, it was ugly. I was not able to increase the scale because I wanted a powerful car so the lightest car as possible. Therefore, I have searched a way to manage the problem of power and design links to the scale and have found thanks to the half life 2 game : the jalopy.


In deed, the jalopy has not a complete bodywork, which permits me to obtain a nice design without overload even through the small scale. Also I have placed a RC motor on the rear axle in order to obtain enough power and have placed laterally the steering motor with 12/12 bevel gear which makes possible the building of a complete system of suspension.  Consequently, the front axle has independent suspensions with double wishbones system which comes from the Rebel Wrecker. Concerning the rear suspension, the motor is attached to the double swinging arm with the shock absorbers on the left side.


The main difficulty was to build around the battery box. In deed, the battery box had to be placed on the center of the car for weigh repartition and it had not compromise the design of the interior. I have solved the problem by using the battery box as a part of the frame : it contributes to the stiffness of the frame. To finish with the return to center steering, I use a modified version of Sheepo’s RTC steering which is very reliable and reactive. Conbining to the power of the RC motor and the fun of the suspensions : the jalopy is a fun RC lego car.

    awesome build! you really have a lot of skill. It looks ver similar to the charger from half life 2, and in real life, but i have one suggestion. the headlights would look better if they were round single piece studs.
    i also really like your rally awd build, with the functional pop up headlights. on the car, do all the wheels spin, or is it just the two on the right? if its only the ones on the right, you may want to attempt to create a lego posi-traction rear differential

    Nice Model! But how do you prevent the RC motor from cutting out using this power supply? The car runs fine for a short while then cuts out (also draining power from the whole circuit; the servo motor for the steering stops functioning)

    I would really love this car if it had seats inside it. It would make it totally authentic. Not bad so far, though

    is there another way to give drive to the rear wheels with out the big black thing u have used because i dont have one

    hay nico is there another way to give drive to the rear wheels with out the big black thin u have used
