If you are looking for "tweak" then you need something like the MIP Tweak Station, which allows you to determine different wheel pressures from side to side. Its an excellent tool for checking the balance of your suspension and chassis.

However, I firmly believe that the HUDY set-up board is overkill, and cannot provide you with any information that you could not obtain and set for far cheaper. I almost bought one to fine-tune my old electric TC3, but then I got thinking about geometry, and haven't looked back.

No set-up board can do more than a person with 2 basic tools can do for themselves for less. Basically all you need is high school geometry (or even a Cliff Notes book on geometry) and a moderate caliper. In the course of my careers, I have used all manner of calipers, some very cheap, and some VERY expensive. For setting up an RC car, all you really need is a $20 analog caliper from someplace like Home Depot or Lowe's. As long as it can extend to about 6 inches (pretty standard) and has a dial that can read in individual milimeters or 1/64-inch, you are all set.

All you need to do is carefully measure the various parts of your suspension, and then adjust the turnbuckles accordingly to create whatever angles you want. Its very basic math, and takes very little time once you know all of the other angles and lengths, just pop off the turnbuckle, measure the length from the center of one cup to the center of the other, lengthen or shorten by whatever amount you need, measure again to be sure, and put it back on.

Presto, perfectly aligned suspension without spending a wad of cash on a set-up board. Besides, its also useful for measuring and accurately setting your shock lengths.
