In fact, the airplane wobbles in straight and level flight on the autopilot too. It’s if the winds are really giving it a hard time. Perhaps dial down the turbulence?
But It struggles mostly when climbing. When level it seems to behave less badly but still wanders around stupidly. Looks like a flight physics issue.
Shame cos most ppl will be using this in career mode for cargo runs, like ME, and that autopilot must be using an old Intel 386 processor from 1993.
FFS.
