I'm using a 1300Mah 3S Lipo btw. That is plenty for a plane of this size. I have read of others using 2100mah or larger batts in order to try to get the plane to balance.

But this just increases the plane's weight more than it already is. The Ryan really needs to go on a diet.

A larger heavier battery further back really doesn't alter the CG much. Because by increasing its size the battery gets longer. But if it is already up against a bulkhead, the way it gets longer is by extending aft, which is the opposite of what you want!

By simply moving the battery forward (several inches in this case) you alter the CG much more, while keeping the overall weight low. We can then ditch the ballast that used to be glued into the front of this plane.
