RE: 1/8 nitro Kind of Dirt conversion to Electric
You have the right stuff there. The 540C 9L is great for this application. Those are the right pinions and the Mtronks Truck is a good ESC. The only way to know for sure about your radio is to try it. Usually, you need a good quality system to avoid any glitching. I'd recommend Spektrum if you can afford a new system. That leaves batteries. You should get good matched 6-cell packs, or even better, LiPo's.
