Forewarning, this will be a bit long winded, but I hope you guys can get a feel for where I am at and help me out. Honest opinions please.
Hey guys, I am a bit, ok probably quite a bit, of a true electric noob... My first hobby grade RC was a Losi XXT kit that my dad bought for me when I was a young kid. Then we moved to T-maxxs, then last year I stepped up to my Baja 5B

. You guys are seeing the trend I am sure, a true lack of purely electric powered vehicles.
Anyways, I am a college student and am looking for something quiet that I can run on campus. As much as I love my Baja, its out of the question due to the noise. Pooop! Soo I started thinking about building an onroad backslash, but after thinking about it, with a road vehicle I think I would prefer 4wd, so 4x4 backslash, then thinking about it again I was thinking revo suspension is notorious for being great, so maybe find a slayer roller and go from there. Ironically, that night I stumbled upon this thread here
http://www.rc-monster.com/forum/showthread.php?t=21901. First off

and 2nd, its like a backslash but with lower cog and revo suspension - its my ideal rc project. (Kudos to Ethan, I really enjoyed reading that build thread.)
So, if I go down that route, it would probably be a project that I would work on as time and money come along, but I am absolutely CLUELESS with what electronics I would stuff in there. My main requirements are Affordability, Reliability, Run Time, and Power - in that order. I like torque and speed, and from what I gather, the new battery and motor technology gives you the best of both worlds, unlike my much loved gas models.
I understand running packs in series and parallel and mah ratings and such, but need some help for what a good motor and esc combo would be. No LHS's in the city where my college is, so if possible I would like some power, but I dont want to tear apart the vehicle at the same time. I am guessing 2s or 3s would be about right, but really have no clue.
Thoughts? Is the revo suspension really all that?
