Ryan (or anybody else who has tried), how far back do you think it is safe to move the battery? I have a YS .91 in mine with the battery mounted at the trailing-edge of the wing (there is a former there). It balances almost exactly at recommended CG. During construction, I cut a hatch in the bottom of the plane with the intention of moving the batter back much farther (since I have keep a close eye on the UCD threads here). Now I am wondering if the fuse has enough strength back there to support a 5-cell 1650 pack? Anybody tried this?
