First Brushless Setup, WOW

Rusty - have you had the opportunity to attach the GPS to your Rustler? I've been in the contemplation stage for a month or so lurking around to see what people are able to run but still don't know exactly what I'm looking for. I've got my e rusty running about 30 now (or 36 way over geared) on 8 gp cells and would like to go just a little faster - 40 to 45 without heat issues would be where I'd like to be. I've seen many posts with the speed recorded by "wicked fast", "way to fast", "almost uncontrollable" but never a true speed attached. I've found that my rustler is controllable at 36 - in a straight line and want to get to the "almost uncontrollable" stage. I bash around with a couple of nitro cars during lunches and am left in the dust.

Thanks!
