Where is the old keyboard sensitivity adjust in BF3?

I allways played using keyboard only to fly planes/jets since BF1942, Vietnam and BF2 (all those games has keyboard sensitivity adjustment), now i can't find that old keyboard sensitivity adjustment, none in the graphical interface nor in console commands, i find terrible to see that keyboard/mouse players have a unfair advantage over us old school keyboard only pilots. Without that sensitivity adjusment i lack precision. Please someone in AE can tell how to reduce the keyboard sensitivity? i don't want to learn to fly whit mouse couse ive done it all my life whit keyboard only! Is soo unfair they have removed this options after all those years making players learn to fly whit keyboard only! I just hope that the adjustment will be back in BF4.
