I believe I mixed in about 6 clicks of up elevator and about 2 of counter aileron and the KEs straightened right out. I just ran a direct thrust test on my OS 160FX with the APC 18x6W prop (it's now on my Christen Eagle) and it has exactly 18 pounds of thrust at 8730 rpm. Should make the Eagle's maiden interesting at 13lbs 10 ounces AUW.
