I am building a 21.5 buggy (no boost/timing in this class) and am looking for a good ESC that will give me room to grow into 17.5 in the future if I choose to. Most everyone at my local track seems to use the HobbyWing XR10 (I think), and I'm not opposed to that one at all - just wondering if this is the best option for me, or if there's better quality out there for the same price, or a little more. I don't mind spending a little more for a better product, but I don't want to spend needlessly for something that I won't reap a benefit of.
