I have very little knowledge on electric motors but wouldn't the wattage draw of a 1700 motor go up as the voltage goes up? In other words to achieve the same rpms with both motors would require almost the same amount of watts?
would figure wattage to increase with the volts but the required amps would decrease because of the high voltage. Which in turn keeps the esc and battery cooler but it would have very little to no effect on the motor efficiency.
The same reason why lower MAH 6s packs are equivalent in run time to a high MAH 4s pack
3.7v x 6s x 3.3amps = 73watts
3.7v x 4s x 5.0amps = 74watts
As I said I'm far from a professional when it comes to these things.
But I can't help but think when I would throw in 3s packs for kicks in our 1/8 cars or buggys our motor temps would drop drastically on either motor(2650 or 1900) to the point we could run 2 straight packs and not over heat.
ESC and battery should bennifet but I can't see motor temps going down, at least drastically
