Mark, I'm not really sure since I didn't do a speed run. Almost as soon as I hit 12.5, I throttled back and started down hill. (I was testing the EIC at different power settings, not the airplane.)
The data shows 162 knots but I wasn't leaning for best power. The SkyView was showing 58% power and 9.6 GPH.

Build the plane you want, not the plane others want you to build!
