I wanted the 108 to be much more practical so I spent awhile thinking about designing a battery tray. I was looking into having a CNC cut carbon one or something similiar. After some more thought, I came up with the idea to just use battery trays from my 700 size heli. They are cheap, strong, and definitely proven to hold up to the abuse they will receive in this plane.

Here are a few pics. I used long flat carbon pieces to spread out the load. They are bolted to the sides of the firewall and to a piece of aluminum angle that is bolted into a former just above the wingtube.
