A couple of things, the original gets really mush around 115Kts on landing pretty much on TO I assume this is part of the roll issue, which should hopefully be fixed in 2, second thing is, my fuel mixture lever,s affect engine performance, I assume they shouldnt. Most planes I simply make sure they are not in fuel cutoff, even planes that dont need them, turboprops, wont start otherwise, but with MU2 I have to have to full rich otherwise left engine glitches. Maybe there is a way to ensure that plane is not affected by the fuel/mixture levers. Otherwise you may have to note that in the documentation.
Thanks
