Here are some little corrections that I found at avsim.ru forum :
Modify the file aircraft.cfg, section [weight_and_balance] :
[weight_and_balance]
max_gross_weight=407852
empty_weight=205029
reference_datum_position=0, 0, 0
empty_weight_CG_position=-5, 0, 0
empty_weight_pitch_MOI=5600000.000
empty_weight_roll_MOI=4800000.000
empty_weight_yaw_MOI=6400000.000
empty_weight_coupled_MOI=0.000
max_number_of_stations=50
station_load.0=0,0,0,0
CG_forward_limit=0
CG_aft_limit=1
This corrects the problem of trembling on the ground and also the total loose of control in case of stall.
2. On some add-on scenery the panel can crash the sim because of a gauge. Comment this gauge in the file panel.cfg, section [Window.01] :
gauge12= // TU-95MS!U008,663,598,355,380
gauge13= // TU-95MS!PU008,460,603,195,187
If you didn't noticed crashes because of this panel, you don't need to correct this.
Voilà
