To make a long story short, at the low and high end of my adjustments I could reach 60.9 mph, but I found a sweet spot right around 10 degrees that would take me to 62.8 mph. I made about 20 runs in order to be sure my results were repeatable.

In my final run I removed the wing entirely and hit 65 mph.

Back to the drawing board.

UPDATE 2020


Was this project perhaps scrubbed prematurely because of dependence on on coast-down testing?

Would have Throttle Stop Testing or another means be a better indicator of success or failure?
