HV questions

[lincpimp]

Ok, to all of the members here with some HV experience, I have some equipment and lipos here and am thinking of doing an 8s setup in my ultra gtp on road car. I have an aveox 36/24/3 1300kv motor, about the same size as a feigao l can. Esc would be a kontronik 40/10/24. And for lipos I have 2 7200 4s 12c lipos. So I would be right at the esc limit (32v) on 8s. Hopefully the batteries (84amp constant)can keep up with this setup. I would gear for 40mph. Info from Briang's calc are below. Watch think?
