Placing the weight in the center section of your chassis..wouldn't that increase the center of gravity? Isn't it better to place the weights on the lowest part of the chassis..on the chassis itself?
on mine it's on the same location as yours but I have the IRS graphite chassis. I also weight the battery, motor and electronics.
the battery is usually the heaviest and I add more weight on the electronic side to have equall weight on both sides...
