I think the point to put everything in the middle ESC etc. Is to center the weight. I had to add 1/2 oz on the right side to make up for the ESC. inthe end it's more weight than really needs to be there. Having the weight center and rear helps traction which we seem to have a hard time getting

I don't see a point to add weight to balance the buggy out of the weight is not really needed if you can run a shorty pack and move the weight to the center.
