At a given voltage, and a given truck/car, it will still take the same number of watts to drive at a given speed -- and therefore the same current.

Very true, but the 1900 i am refering to is effectively a 1512 1.5Y with twice as much resistance. Also, out of curiosity, I decided to gear the 1900 20/46 in my 8ight to match the theoretical top speed of the 2650 geared 14/46, and the 1900 was slower, was sort of sluggish, and ran cooler, meaning it used less power. Actually, I have noticed that the MMM heats up the most when using low throttle, i.e. racing on a track where the average speed is 15mph, vs. bashing out in the street or a grass field at 40 mph. With a 1900, i have to use more throttle input to get the same speed, causing the esc to run cooler as well. Those were just my experiences that led me to assume the 1900 on the MM Pro was ok. In fact, I don't even use the MMM fan with the 1900. I don't need it and the connector and solder joint to it broke off anyway. It's also a V2...
