Electrics for Cat?

[cAptainslow]

Appologies, im sure this has been asked a million times and im also sure that a lot of this is down to personal prefference....but...
what motor/controller would you recommend to someone (erm..me) who hasnt raced for quite a while for a lipo cat?
Im on a bit of a budget 'cos starting again aint cheap of course but also i dont want to be kicking myself if im miles off the pace or going up in smoke! Im running Ko 40fm radio gear and have read other threads which note that Novak kit can interfere with it.

Any advice would be appreciated,
Cheers...C'nslow.
