I just got my new pelican 1600 case and really like it. But I'm having a problem with the sides leaning between components. For instance, I don't use the charger when I fly obviously, so when I take the copter out, that side leans in toward the larger opening. Is there a way to reinforce some of the sides? Something that would look decent. I have seen the laser cut foam that I could order, but I don't feel like spending another hundred bucks. Also, Should I secure the layers together with spray glue? Top to bottom layers.
