At least that's what I've been reading in this and other forums. Is there something I'm missing? I guess one advantage is the current ESC of choice (Mamba Max) can be run on 3S without an UBEC, but I assume it would run hotter due to the greater amp draw?
The other thing I've read is that two equal weight batterys (ie: same # of cells), but one is 3S and the other is 4S, the 4S will give a bit longer run times (even though the 3S has more Mah) because volts are more efficient than amps. Obviously, each has to have a motor that is optimized to its voltage for this to be a far test.
I'm getting ready to convert an 8ight so I've been reading up a lot on the choices out there.

Perhaps im better off looking at the 1Y which works out to be 40700RPM with a 4S battery.
