Holy Shoot, but she is gorgeous! I'd be afraid to put her in the air! As for the battery, I don't know man. You obviously can't belly land that way. It protrudes too much from the fuse to protect it with foamboard. I have not built one of those, yet. Notice also, what it says under my avatar. True statement. Just looking at your pic, it seems like the battery should be on the inside, rather than outside.
