It took under 90 minutes to change the prop. The lugs came out with a few taps, except for one that I had to use another lug to force it out.
I have it set to 26.8 degrees. Climb is still >800 FPM (not at full power) and I was at 125 true at 5200 RPM (5.5 GPH per the Dynon). I didn't try full throttle because it wasn't smooth enough. I really like the 117 kt cruise at 4900 RPM using 4.5 GPH. This is 80F at 2000 AGL.
e-props gave me their digital level tool, even though I didn't order it. It seemed to work well. I did check my cell phone against it and got the same answer to within a tenth of a degree.
