The problem with "go get motocalc" is that most people don't understand the numbers that motocalc gives them. To use motocalc effectively, you need to know what you're doing. Otherwise, you're just stabbing in the dark, and more likely to come up with a bad setup than not.

A more helpful answer here is: Use a 9x6 or 10x6 propeller.
