I'm having this problem as well flying the Baron. It is all I can do to keep from crashing on takeoff it is so bad. After liftoff it veers left or right and I have to fight to regain control until I gain enough altitude for it to calm down. Same issue on landing. I tried both Legacy and Modern with the same effect. I have also tried changing the weather to sunny and calm. I am using a Saitek Flight Pro yoke and pedals. Any ideas??? I would hate to have to go back to FSX after spending $120.
