Need help figuring out budget brushless for revo!

[R00ST]

I used to have a brushless revo (back before there WAS a BL-E-Revo!) and ran it on a warrior 9920/9xl on 14 3800 nimh cells (this was when lipo was just coming out and I didnt have 500 to drop on batts/charger lol).

I loved it...but got out of rc. I am back now with a BL crt.5 (MM/vxl motor) on 3s. I enjoy it but I think I miss having a slightly larger truck that can tackle some more serious offroad stuff.

I am considering buying a E-Revo roller and going from there.

What is a good setup for the e-revo? I dont want to spend a ton of money so a cheaper controller/motor is best. I dont have a ton of time to use on rc so I would rather have to replace a 50 dollar motor after 20 hours of running rather than drop 200 on a hand wound motor.

I have heard totally mixed results on the MMM...can I run a MM Safely on 4s? Is 4s enough for an e-revo? Can I run 5s without running a single 5s pack? (run a 3s and a 2s pack)? I think 6s might be a BIT more than I need. 45mph is about as fast as I need on a revo.

What do the e-revo's battery boxes even hold?

How about some budget lipo's? I have two 3s 5000 "red packs" from ebay that held up pretty well to my abuse and they were only about 40 bucks each about 1.5 years ago.

Any info you guys can give me is much appreciated!
