Patrick, you're right. It doesn't make sense. Believe me, I didn't spend over $800 to go slower. I don't know that it is the motor that is letting me down, or the controller.

I did, however, notice that the motor than I got seemed to have been shabbily put together. There were breaks in the insulation on the motor leads and breaks in the insulation at the holes where the leads exit the motor.

Then again, I had the same disappointment when I got the 1512 1.5Y. I was expecting performance on par with the Feigao 9XL, but it wasn't there. It turned out that the motor needed higher gearing to get me to where I wanted to be.

I'm thinking that it may just be in the ratings and that I may have made a mistake in thinking that a 2700kv nue would perform like a 3100kv Feigao.

Unfortunately, with the tires that I want to run, I'm out of gearing at 20/44 and 43/13 in the diffs. I just went back to the 1515/2.5d running 18/44 and bigger tires on 5S. Now it's haulin' butt and running cooler.
