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.
RACE2 is the fastest LEGO off road car. The 4WD RC car can get over rocks and obstacles fast. It is an improved version of my original RACE car. The building instructions are available as well as the LEGO Digital Designer file (LXF). It is a simplified and more robust version of the original RACE car.
Here is the 3D model in Sketchfab exported from Stud.io. Unfortunately Stud.io does not yet have the L-motor (88003) in their parts list, so you have to use your imagination to fill the gaps.
