Great looking rig, you will love it, the e-lst probably get ran more than anything in my stable. I can measure if you want, a hyper9-e battery tray may work for you, and save you the time of fabbing up another one. Judging by where your box is touching the trans, and right behind the servos, looks pretty close to mine. I can measure if you want, might save you some time, and they are pretty cheap. This is the only pic I have of it right now.
