Hello people, I am still looking for a solution for my problem but I just wanted to add somethings.
I can check the rudder input in the simulation, it is starts at 0.000 and stays there if there is no input and the plane moves straight. -1.000 is full left rudder while 1.000 is full right rudder. Planes slowing down starts almost at -0.250 or 0.250. when on the half rudder like -0.500 or 0.500 plane is already reaches a point where it stopps or slows down to 2-3knots of ground speed most of the time. I have never managed to make a full rudder and make a turn, its almost possible with a full thrust to make a sharp turn. And yeah, thats ridicilous.
