looking for a new stock?

[PrIeSt]

I currently have a magpul moe stock.

But am trying to move a trigger master and lipo into the stock area, I like how clean and simple the pts looks. but i need space for a lipo, trigger master and wires.

I have been eyeing the CTR.. Wondeirng how much space is actually in there. and if a small compact 7.4v lipo would sneak in there with a trigger master, lipo alarm and possibly a small fuse?

hard to tell the space from the images.
