Newbie advice

[welshcarter2012]

Hi guys !
Im pretty new to all this and need some advice / info regarding racing
Race cars and generally everything !!
After visiting my Local RC club (Caldicot South Wales ) for about 5 weeks I
Eventually brought myself a 2nd Car .. Pretty much on advice from every1 else
It's an Associated b4 Or Apparently the X6 converted so ive been told !!!
Anyway so far so good but I'm just looking on advice on setups or upgrades I can do !!
The guys looked at it and said it wasn't running low enough so they've looked at that but I'm looking for any extra help rhats out there .
Currently it has a 7.4 v 5000mah Lipo in it
With a few turnbuckle upgrades .
But other than that I'm completely blank with it !!
Any tips guys ??????? Please !!!

A very interested Newbie
