Been working on it again tonight. Once I test-fitted the motor, I decided to do some watt-meter pulls with some different props. Started with 4S and an APC 8-6E. 104 amps. A bit much. I must have sorted through 50 or 60 props and couldn't find anything I wanted. So I cut an APC 8-7 sport prop down to 7" diameter. I got 79.4 amps out of that one, 1131 watts. That will be my starting point until I can find some more suitable props. The LHS didn't have any, either. Figures. I ditched the spinner, as it was preventing good cooling airflow. I'll finish the airplane before I do any more test runs. Here's the progress.
