an2 is a Taildragger so i guess the <max_steer unit="DEG"> must remain -10 I guess the recent improvements you made regarding Gears can explain the an2 problems with <relaxation_velocity> the problem is solved Regards -- Gérard ------------------------------------------------------------------------- Take Surveys.
