justpoet: Battery, I mean fuel tank, box looks to be a little over 45mm wide. There is one attachment point that passes a bolt through a motor mount, but you can easily make up for that with a couple nuts or a little standoff.
Hmm, seems that's too narrow to put a normal 2s battery in then, at least in the standard orientation. Perhaps the lipo on its side would work, though that would raise the cg back up a bit...or maybe some dremel work.
