6s vs. 4s?

[lincpimp]

If you go from 4s to 5s, maintain the same overall gearing and run the motors at the same speed the difference is quite noticeable. 6s makes a world of difference.

I have run some heavy vehicles on 4s, and then gone to 8s setups, with half the motor kv, half the amp rated escs and crap batteries wired in series. Even then the difference was noticeable, and my 8s setup cost about half what the 4s setup did (or less). If only we had an available 60 amp 8-10s car esc from castle, I would never run anything lower than 8s..
