X2 Astro setup

[RichH]

Hi guys
I'm just getting back in to racing after a long break and have got myself a cheap X2 pro to see how I get on. I know the fashion is mid motor but at the moment skill is my limiting factor and keen to set it up the best I can given the limitations of rear motor. At the moment I'm running it stock but with 70g weight on the servo, it's OK but sure it could be better. Has anyone got any recomended set ups? How much weight should I be running up front?

thanks for the advice
Richard
