Thanks alot, as I said in the other post, this has to be the most friendly and helpfull forum I have had the good fortune to find.
As for the motor/ESC I think I will go with this set up

I'll grab those bits for the mad rat, actualy thinking wether it would be better to order two xpros instead, as I assume that kit comes with those already?
