Joe,
The motor I would recommend for your set up on 10S would be the 1915/3Y. You should go up to the 20x12 prop to be more efficient, because you would increase overall rpm's. We have not received the full information from Neu Motors on the 1917's, this is why they are not in the Prop Calculator, but based on our knowledge of them, the wattage of them would be too high for your controller to handle effectively. You did not mention what type of aircraft you have, so I am going off of a general set up for you.
