Thanks alot everyone. The last few days I have been working very hard, trying to get this thing finished so I can use it on the weekend. The throttle, which seems fairly simple to make, actually took me a WHOLE DAY to get working. It has definately been the hardest part of the project. The steering, on the other hand, has not been hard to make at all. All I had to do was mount the servo upside down and rig everything up.
At the moment, all I have to do is just make the exhaust, breaks, mount the fuel tank and make the rollcage (but that can wait a while)

By the way, do you think I should use monster truck wheels or just the standard buggy wheels?
