More Voltage = Less Amp Draw?

So to get the same 1.2 or whatever, horsepower (900 watts) using an 8s setup would only need to pull 30 amps. Which also means less heat, more efficiency. Also, because of the lower amps... the battery voltage will not drop as much, so you need even less motor to make that 900 watts... or you get a little bonus... maybe the battery holds at 31.5V instead of the 30v... that's 945watts.

Hey that's 45 watts for free... so I was wrong about the nothing for free thing. :)

Yay! Free power! Thats gotta be the best thing I heard all day.

Hmm, so 60A at full throttle on 15V. I'm running 30V (to be safe) and my motor is rated 770 (say 800 to be safe). 800/30 = 26.7 - which is alot less than the battery and speed controls rating. Sweet! This is gonna be a fun project (but does anyone think this may be too much motor?)

Well, off or not with the servo lengths, the packs should fit with room to spare.
