Roll control of aircraft not setting

Hello

I’m working on a jetliner and hope I can make it fly as realistic as possible.

I think I made a lot of progress where the flight model is tuned accordingly and it is already possible to make a good flight.

However, I’m having problems with the roll and elevator controls.
I have spend a lot of time searching the SDK documentation to find a solution.
With this I have tried to adjust to following:

  • Aileron and Elevator effectivnes
  • Roll and pitch stability
  • Elasticity Tables

Nothing works!

However, I do not think the problem rests with these settings because I’ve noticed the following during testing of the aircraft:

  • Right after take-off I can use the roll and pitch controls perfectly until about a hundred feet after takeoff
  • When I start flying in mid air, the autopilot is active however without alttitude settings. Therefore I can go up and down and in this case the elevator controls are loose.
    We I deactive the autopilot, only then the roll and pitch controls are suddenly very heavy again.

Can anybody help me by suggesting possible issues?
Anyone else had this problem?

Thank you
