Thanks for the heads up. 4s will be sufficient for now... but I may get the speed bug by the end of summer. We'll see.
I've been spending some time with some smaller aspects of the build... like an ESC mount and putting together a CC BEC adapter. Here are some photos:
ESC mount. I used my Rustler's stock mount. Hopefully it's sitting high enough to clear the shocks, and hopefully it's large and sturdy enough to accommodate the 80B. I may order a purple RPM mount for the Rustler to keep with the color scheme.

I used some extras that came with my toe-links as pseudo-standoffs:
Here's the adapter for the CC BEC. I want to be able to use it with different ESCs or if I ever want to switch. I wrapped it in electrical tape to hide my shrink wrapping mistakes. :P
Lastly, here's the body I'll be using temporarily:
I have a Parma Ford Expedition waiting to be painted in a basic black to purple fade... and I'll be having team3six paint up a HotBodies F350 body with blue ghost flames overlain with purple ghost flames in the future... hopefully.
