I have a couple of them sitting around*, and I have the two Neu 30C 3300 5s packs from FMA. I just need another controller, probably another LT-6s 150A (

), some pinions ,and I'll need to make a dual-motor mount. In the event the diffs do go nuclear on me, are there upgrades/mods available?
*Both are the 1650kV versions.
