Well, for your radio, figure out what is cheeper, the radio you want and 3 extra sets of crystals, or a synthsized model. As for brand, i use both a JR XR3 and a Futaba 3PK. It really depends on how into the sport you are, how into the sport you want to be, and how it feels. I know some people that stick with the stock radio because it just feels best to them. But, always go a few steps up, if you have the money, that way, you dont end up buying as many radio systems as you get mroe into it. I would say the same with a esc. I highly reccomend any duratrax product, just because of their customrer support. I spraypainted a few plastic parts, and they melted, so duratrax sent me new ones, didnt even charge shipping.
