Greetings, Mustang1972(hope that refers to that beautiful car?) Thanks for that.I was only doing a test flight to Poland, and had laden with full fuel, but I could barely climb and was at under 10k when it started. Will do. EDIT: Do not have that entry in the 707-300C aircraft.cfg.

This is from my 707-300C aircraft.cfg:

[flight_tuning]
cruise_lift_scalar=1.000
pitch_stability=1.000
roll_stability=1.000
yaw_stability=1.000
parasite_drag_scalar=1.000
induced_drag_scalar=1.000
elevator_effectiveness=1.000
aileron_effectiveness=1.000
rudder_effectiveness=1.000
elevator_trim_effectiveness=1.000
aileron_trim_effectiveness=1.000
rudder_trim_effectiveness=1.000

So it should be there! ;)
