Checking for Chassis Balance?

The MIP tweak station gets the job done. However, check to see if the bubble level really shows level. Mine was way off. I compare the height of the ends of the pivoting arm, and ignore the bubble level.
Easy way to check bubble levels...... Place it on a reasonably level surface, note the position of the bubble, then turn it around, the bubble should be in the same place, if not, the bubble level is off. Hope that made sense.

yeah the Mip is easy. Simple set it up, level the front bar, then attatch the pivoting bar and begin the process.
The "key" to doing this though is building the car's shocks and supsension equally before you start. Not doing so can cause big headaches when you try to "tweak" the car.

Well this thread inspired me to build a scale system. Here it is. This is my XXX-T MF2 setup for dirt oval.

Sweet. Nice job. Are you able to level the base? If not you may be able to find something in the hardware section of your local big box. They make all kinds of adjustable feet for furniture and appliances.

Yea. See all those dials? They are attached to leveling feet. And I have two different kinds of surface bubble levels I use to level it.

I got the scales on sale at www.oldwillknottscales.com for right at about $100 total. The melamine board was about $20 at home depot. I had them cut it to 20" x 18" which is a couple inches more than needed for a offroad 1/10 scale truck. The contact paper was another $5 and the bubble level was $3 at home depot. I bought some leveling feet at Home Depot but they just weren't right so that was about $5 wasted. The leveling feet I ended up using were about $5 and the inserts which mate to the leveling feet were about $2, and the knobs were actually pretty expensive, they came up to $10 and I picked these up at True Value. I bought another bubble level at True Value for about $3. So total in parts is right at about $160. Although if I was going to try to build this today, I would have to add an additional $40 because I had $10 off each scale that day I bought them. The scales have a 30 year warranty though .
The tools used were a compass, 1' and 4' ruler, a 90 deg angle, digital calipers, scissors, hobby knife, drill press, and bits up to 3/8". I also used the girlfriend to help me hold the board as I was drilling and she is the most expensive out of all this .

I didn't say she wasn't biotchin about it

I took it out for the first time after using the scales and there was definitely a noticeable difference. Last week my truck was pushing real bad (dirt oval racing). No matter what I tried, I was just pushing. When I threw it on the scales the first time, it was so off in balance. I don't have my notes with me, but I had something like 470g LF, 320 RF, 520 LR and 670 RR. I moved a few things around, tied down my wires, took out some slop in the suspension and just did a bunch of general maintenance. Then I got it to the balance you seen in that picture.
WOW what a difference. For starters, I had all the steering I needed, actually I had too much steering. Just a little bit of steering input was all I needed. During the middle of the turn, I don't think I was steering at all, it was practically steering itself!
I used the setup board in my pit spot, I just covered it with my pit towel. After each suspension I made, I balanced it right before I hit the track. In our oval class, we had nine entries. Seven of the entries were 4WD using the new Yokomo, BJ4WE, and Kyosho Lazer. There was another guy there either using the B4 and myself using the XXX-T MF2. Even though I was 2WD truck, I only about .4 sec off per lap compared to the leader in the Yokomo. w00t!

Here are the results. I am car #0. I was doing pretty good until my topshaft melted in my transmission . The winner was car #4 in a Yokomo MR4BX

Wow that dude in the Yok is consistent. Great job on the tweak board. I'm going to make one even though we have an off-road track. I want to see if it helps. I used one with my kart and it really helped to understand what changes did before hitting the track.
