Weight Placement

[Eliminator Racing]

I normally put about 1.5 oz behind the axle the rest in front, tungsten cubes. I try to put the cubes even from side to side. I read where someone said to put more weight on the dominant side of the car does this make a differance and why. I do not have a track to test on.

Your three wheels form a triangle. You want the COM of the car to fall within the triangle. This is usally not a problem. Derby Dad has dropped a few hints about off setting the weight. There must be some speed to be found. Since you do not have a track perhaps offset only a cube or two until you find evidence of a more drastic change is helpful.

Here is a picture of the triangle that exists on every PWD car (that rides on three wheels).

There are some tracks that are very long that benifit from a center car weighting. In those cases moving the weight towards the DFW is required. In more normal cases not required but perhaps some speed if you can unleash it.

W racing -

Thanks for the picture & explanation.... I read this question and went to look at some of the racers showing some set ups. I did notice they set weights to the one side verses centered. With this picture it just made it really easy to see why..

Thanks V

So what you are saying is keep the com. 1/2 to 5/8 and keep the weights inside the triangle.

Which wheels and which track?

We have Cheetah wheels move weight towards DFW and at Districts they have four tracks 35' to 42' / com. in front of back wheels

Keep it at 5/8s and the weight will be in the triangle already. The advice to move over the weight did not include how much or how far and would require experiment. I would consider moving one or two cubes over insead of cenering them. It would take testing to narrow it down further.
