I built a new version of my Race cars series (Race1, Race2) with the logical name Race3. This time I am using the SBrick to control the car which gives its proportional steering control. This is great for driving curves. Race3 features individual suspension, ball bearings and a very low centre of gravity. You can drive it up and down pretty much any rock or mountain. Here is a video of what it can do.
And here are some photos of the model. Building instructions are also available. I also put up this MOC over at Rebrickable.
It has long been a dream of mine to build a remote controlled LEGO car. LEGO has many Technic cars in their program that use the Power Functions to remote control certain functions, such as opening doors or lifting an arm. Power Functions use infrared light for communication between the sender and the receiver. In the past, LEGO also had remote controlled cars that use radio frequencies, which is much better, since it does not require a line of sight and has a much further reach.
