So my father inlaw is loving the looks of the Flux HP. Our local hobby shop has it ready to run (w/o batteries) for $550. What are some owners opinions on this truck and what batteries do you run? He will obviously run lipo, but he wants 4 2s lipos, I would assume 30c or more, and atleast 5000mah. I told him a lot of people on here swear by the lipos rcecho has. What names of the lipos are the most reliable, like Turnigy and such? And what discharge rate do you recommend for the big 1/8 Flux? Thanks.
