Why not put the power setup your talking about in an EF1 electric racer. They are suppose to be quick on a 4cell, with the right 6 cell setup up they might give the Q40 guys a run for their money.
Go with something like the Proud Bird from Tower Hobbies, it also looks right with a prop on the front.
