MP777 SP2 Brushless

Ok, so for those of you who viewed my thread questioning buggy weight, here is the beast:
Details:

The buggy currently weights 7.4 lbs without batteries and the battery boxes are designed to fit Maxamps 2s 10000mAh batteries (will hold 2 batteries for 4s total voltage).
Due to the weight issues, I might convince myself of 5000mAh batteries, but the verdict is still out.
I calculated that my battery boxes weight a combined 0.6lbs, so I figure I can thin them out (mill/cut off un-needed sections) and save maybe 0.2 lbs.
I have a few other things I am going to try to save weight with, hopefully getting the buggy down to 7.0 lbs without batteries.
I have yet to finish the battery straps (velcro based) and I still need to mount a short antenna post.
The "o-clamp" motor mounts are from megamotorsusa and I cut the Novak heatsink down and mounted a fan on it to try to keep the heat down.
My plans for this buggy is mostly as a basher, but I also plan to take it to a local track to "race" (they probibly won't let me accumulate point for their championship, but I really just want track time.)
So... How bad is it?
