I've had rudder and elevator issues with it in both P3D V4.5 and V 5.4 click here to see video.
As you can see from the link, the rudder and elevators flap (twitch) wildly till air born. Other then that, it is fine.
Someone on another forum suggested to turn the yaw damper switch off, I did and that worked for a few minutes then
started with the twitching. This was for P3D V4 SP1 - don't think they ever updated it any further. Like most other devs,
they ran over to MSFS 2020 and forgot about P3D series. When you open the link, wait a few moments for the jet to start
moving. Anyone out there have this issue and a fix for it?
