Going to start over again, I have put the smaller K planes on, and I am going to go back to the original X dimension and take the spacers out and try the 3 sets of props that I have one of which is the rounded ear props and see where it takes me. I now have access to a ramp that is 5 minutes from my shop building so I can leave my tools out and install the spacers as I need to see what work with what.
