There is one thing that a few of you need to understand before you can tell me that I "don't get it"

First off, motor resistance goes up by the square as kv reduces. For example a 1000 kv motor will have four times the resistance as a 2000 kv motor of the same design. Energy loss through heat is (resistance)(amps^2) so even though you may be drawing half the current to get a given power output with the 1000 kv motor, the same amount of energy is being wasted as heat as the 2000 kv motor when it is drawing twice the current.

The same is true with batteries. If you have a 4000 mah 6s pack, it will have 1/4 the resistance as a 2000 mah 12s pack because each 2000 mah cell has half the resistance as each 4000 mah cell and there are twice as many 2000 mah cells in series. So again, even if you are useing half the current with the 2000 mah 12s pack, you still get the same amount of heat as you do with the 4000 mah 6s pack.

This also applies to escs. You will get the same amount of heat with a 100 amp esc that can handle 12s verses a 200 amp esc that can only handle 6s, because in order for the 6s esc to be rated a 200 amps, it must have fets that are 1/4 the resistance as the fets used in the 12s esc.

Wires? Use 1/2 the guage and/or shorten them and your set.

I admit that in reality, 12s will run cooler because it is difficult to change all of these factors at once. And in reality, high turn motors are wound better because smaller gauge wire is used.

One last thing. Some of you are saying that "lower kv motors have more torque." That is a very ambiguous statement because that is only true under certain circumstances. That just like saying 12x4 is bigger than 8x6 because 12x4 has a 12 in it. Because kt is directly inversely proportional to kv, the 1000 kv motor will have twice the torque PER AMP as the the 2000 kv motor, but since the 1000 kv is pulling 1/2 the amps, it will have the SAME torque as the 2000 kv motor.
