Has anyone found a hard case lipo that actually fits this battery tray? I plan on running 4s and the smallest I've found so far is a promatch 5000Mah pack at 47mm, while the tray is 46mm. Of course I could run a 3600mah, but I'd like something at 5000Mah+. I dont understand why it was not made a bit wider to accept more of the larger packs, and probably soon to be 6000-8000 hard cased packs.
