Brushless setup for E-Revo ???

Hello

I was wondering if some one here could help me with a brushless setup for my E-Revo ?? Rigth now I´m running HV-Maxx 4400 and 7 cell GP and IB´s on standard Revo wheels.

I have been mailing a little with Mike (RC-mosnter) and had decided this setup:

Feigao 540c 7xl
Quark 125B monster pro
UBEC

Is there anyone here who runs that setup and can tell about it ?? Is it smooth like ex the HV-Maxx systems (have concidered the HV 4.5 - but not sure it has the power I want)

What about the warrior 9920 controler - is that ok ??

Is there any better ideas ??

What Lipo setup would be good to go with ??

What kind of setup would you be choose ??

Hoping for lots of advises :032:
