Flight Dynamics how to reduce wing level stability

[Blaunarwal]

I have a Su-33 which is very stable, always rolls back to 0 degree rolling, without any autopilot wing leveler. Which parameter do I have to modify if I want it to keep the rolling angle? roll_stability and empty_weight_roll_MOI seem to have no influence.

You have to use the air file for that. Section 1101
Experiment with a combination of Cl_beta_roll moment-side slip and Cn_beta yaw moment-side slip

Thanks a lot, will give a try.
