Uncontrollable aircraft. SendPOS changing heading

[a533]

Good morning.

When I send the SendPOS command, if I don't change the Heading, it works fine. But when I change the Heading significantly, for example, to the opposite direction, the plane becomes uncontrollable. It's as if it struggles to return to the original heading. Is there any way to solve this? Everything else works great, thanks to the authors.

Thank you.
