Hey everyone, Im a Newbie who just bought a Slash a couple weeks ago, have been beating it up and this thing is badass!! Anyway, thinking about doing the Traxxas Power Up option and sending back my Titan 550 for the 3500, etc. Anyone have any experience with this? Pros, cons? Is this truly plug and play or will I have to program my 2.4G controller to match the new ESC? Dont know much about the Lipro batteries either but any good suggestions for a beginner? Thankx for any help you can offer! Look forward to learning more!!
