How to create a cool LEGO remote controlled car.

In our house we love to play with remote controlled cars. But RC cars in the kid-budget area tend to break after a few hours of use.

Not long ago we shopped a bit a Lego.com and we got some of the “motor” pieces that normally only come with some of the largest Lego Technic sets.

And very quicky, a remote controlled car in Lego Technic was put together, and it actually gave the same play ability as a normal remote controlled car, plus the entire Lego universe. And it seems unbreakable – If something “breaks” – we put it back together again, or perhaps a new car is suddenly a reality.

The center piece is the “88004 Servo motor”, a motor that gives a 180 degrees turn and can be controlled with any of the IR remotes from Lego. We had the IR Receiver (8884) from a Lego train system and we got the 8885 remote controller.

A motor and a battery box is of cause needed, the standard 8293 motor set will do fine, however, if you want more power, the new L-motor or XL-motors are great for speed and power. We use the L and XL motors that reason.

Watch this small video for a demo of the car:

Here are links to the three pieces needed – Total investment if you already have a motor set is $50 – Not bad for unlimited supply of different remote controlled cars.
