My competitive eye sees a little more work being needed:
1) The leading edge needs to be sharpened to reduce drag. I know, it's a work in progress, just calling it as I see it. This is the last step that needs done so don't worry about it until after you've finished your other fitting and testing
2) A flat spot needs to be filed into the round shaft where the set screw is located. This would prevent the shaft from working out of the collar and causing a loss of steering
Other than those two, I LIKE IT
