HI,

I really don't like the idea of putting the battry forward of the fire wall. Putting it under the fuel tank is still forward of the CG and any weight ( lead , etc ) added under the motor would not be that much. I always put my battery inside a plastic bag , even under the fuel tank and its wraped in foam. I don't like going against the grain here, but the battery is one of the most important part of the plane. But do what you need to.

Plus, when you get over 10 planes or engines , they become invisable to the wife. Its like hiding a tree in a forest. Just not easly seen.
