My interest would, not so much be the flite box, but what's in it!
I'm more interested what's ON it.
I subscribe to the box style combat guys use. They try to put all the essential pieces on the outside of the box that might be needed when you go to start the model. This way, there is not reason to rummage through the box for a prop nut wrench or a RPM gage or glow driver. The ONLY things I keep inside are things that are secondary or don't need to be picked up: batteries, fuel containers, lines and handles. This approach also keeps the box size to a minimum which in turn translates to low weight. I only wish I had a way to mount a roll of paper towels.
Hey! I just got an idea! I don't need a roll! I can just use square napkins! I can easily create a small slot for keeping napkins! Off to the basement to modify my frankenbox!
