Hi everyone, I have two problems with the DA40NG By SimSolution on my xplane 12. I have a permanent roll to the left effect and I have to always counter it by right roll, I precise that I'm a real pilot and it's not p factor or other physics, it is unflyable for me on xplane 12. Anyone has the same problem or the solution please ? Second problem, when I put some power I had problems with RPMs : I increase power, it increase, then I discrease power to idle, power decrease to idle but it increase again to about 1500 RPMs without adding power and it do this to me at every stage of the flight. To obtain idle power I have to increase my throttle a just a bit about 1/2cm.... Any ideas ? thanks a lot !
