You can't really take the ribs off the bottom, because of the screw lug incorporated into them. The old 8ight 1.0 tray didn't have the ribs. It only had the screw lug, and it didn't provide any more room than the 2.0 box does with the ribs.

What we really need is a taller/bigger battery lid. I see no reason for the tiny size of the losi lids. I'm sure they could have made them much larger. I'm actually surprised there aren't any aftermarket lids sold that are larger. I'm sure if someone made one, it would sell like crazy.

The losi lipo and standard nimh hump packs fit fine with the included lids, but that is about all that will fit. Even the losi lipo is a very tight fit. You can find low mah lipos that fit too, but most want at least 1500 mah in a pack.

OK done with my little rant. IMO the problem is not the box, but the lid.
