It's not so much an advantage, it's more of picking the right tool for the job. After that you have to gear properly. I've heard of people smoking motors left and right, but the real problem (I think) is trying to get too much out of too little. I don't have any problems, but I think many people would think my setup is conservative...I think it's properly set up, and that the rest of the folks out there set theirs up too aggressively.

For instance, I think that 4S has no place in anything 1/8th buggy or MT sized. Now I know lots of people are going to yell and scream and tell me that I'm a moron, but hey, that's just my opinion, no need to flame me for it. I just find high voltage more conducive to a nice running setup. I'm running a 6S A123 (yeah, I know, it's 5S lipo equivalent) pack through a 10XL geared 14/46. It's set up for 40 mph, which is plenty to get the job done. Houston is hot as heck in the summer, and my setup consistently runs 150 - 160, even on days with high humidity and temps reaching up into the 100's -- and yeah, with one of those el-cheapo "hot" Feigaos.

It's true my environmental conditions impose limits on me, which I have to overcome. That leads to a setup that stays well within the limits of reasonability. I know lots of folks run 4S setups and don't have problems. That may be, but I don't think they'd do well down here. I'm happy to run a cheap motor and lots of cells to keep my temps down. I have more performance than I can handle, and I get to save money.

As always, YMMV.
