Now that my X is up and going been thinking of getting into the electric seen now. Looking at the RTR flux (HPI Savage Flux #104240) My questions are can I put a 3 speed trans in it? I'm not messing around and going for the 6s LiPo's I don't know what is a good battery that don't cost a bunch of cash. After the esc and motor burn out I want to change up to the 8s batteries and stuff. I did some looking around for a 8s esc combo but not sure what I'm looking for since I am coming into this un-knowledgeable. I'm going to guess that I will need a different charger and stuff so should I just upgrade to the 8s stuff now or not? Anything else I should upgrade running wise, I of course am going to do the basic stuff that I have done to my X will follow suit. Thanks in advance guys/gals.
