Philip, thanks, you are welcome, no problem, the update is easy, just import 1534 with all zeros. Let me know if you find anything else, I am testing, but didn't find much difference beside increased overall stability, remarkable in the autopilot: this is what I use so far for the cfg, just a first try, but working very well....Ciao Martin[autopilot]autopilot_available=1 flight_director_available=1 default_vertical_speed=1000 autothrottle_available=1 autothrottle_arming_required=1autothrottle_takeoff_ga=1autothrottle_max_rpm=98.000000autoland_available=1pitch_takeoff_ga=8.000000 use_no_default_bank=1use_no_default_pitch=1default_bank_mode=0max_pitch=10.000000max_pitch_acceleration=1.000000max_pitch_velocity_lo_alt=2.000000max_pitch_velocity_hi_alt=1.500000max_pitch_velocity_lo_alt_breakpoint=20000.000000max_pitch_velocity_hi_alt_breakpoint=28000.000000max_bank=25.000000max_bank_acceleration=1.800000max_bank_velocity=3.000000max_throttle_rate=0.100000nav_proportional_control=9.000000nav_integrator_control=0.250000nav_derivative_control=0.000000nav_integrator_boundary=2.500000nav_derivative_boundary=0.000000gs_proportional_control=9.520000gs_integrator_control=0.260000gs_derivative_control=0.200000gs_integrator_boundary=0.700000gs_derivative_boundary=0.200000yaw_damper_gain=0.100000default_pitch_mode=0

waaahoooo...thanks martin, it works perfect. now my birds lift of as they should do..tom
