Wow, this is a difficult post to answer. In the Racer magazine article just out, it says the X - 5 is for the experienced hobbiest, and they are right.
Now if I bought a used R/C car, the first thing I would do is disassemble the entire thing and put it all back together for two reasons. First I'd know for sure it was right. Second, I'd be much better able to repair it, and if you know anything about my driving ability, you'd know why I say that...
The X - 5 instruction manual is on the Tech section of
www.4wdrc.com in glorious color if your car did not come with a manual. If you want the printed version, E mail me,
[email protected] and we'll hook you up fairly cheap.
One thing sure, I wouldn't run a car with a nasty noise more than 6 inches...
