I have a 1930. It is a 6t and a 10t. The motor seems better built and quality than the others. That in turn makes them more efficent. I ran a 1930 10t in a emaxx. It was good power and run time. I want to try a bigger one. like a 1940 or 1950. If you try a 19 series and stuff you will see a difference.
