Mini LST brushless motor

I'm getting one of these later this month, birthday and all that.
and have already decided the stock set up will be too slow. (they always are :) )

so any sensible ( no really the 7XL is a tad big) suggestions as what would be good to put in it.
I want a single motor set up with good torque rather than crazy rpm.
I will be running at 7.2 X1100mha and need a good five mins running time.
I think the stock cans are 380...I maybe wrong though. :o

wada ya think guys.
