I'm trying to tweak the aircraft cfg on the lionheart Dynamic so it behaves more like how want a LSA to fly. To me it flyes lika a propliner and isn't light slightly twitchy as i think a LSA is.
I have fiddled with the rudder effectivenes so now it responds much better to inputs on the stick and moves around in the sky as i want it to.

The thing i have left to correct is that it flyes nose down when banked into the turn and doesn't sink, i want it to loose lift when banked so i have to raise the nose so to not loose altitude.

Is there anything i can change in the aircraft.cfg to get it to behave that way?

I know that this might not be true to how the dynamic flyes in real life but this is the way i want it behave.

I might be wrong, but aircraft aerodynamics is controlled by the .AIR file. You would have to tweak that one.

The LSA's are designed to be stable, for pilots of limited experience and ability to be still safe and have an enjoyable time. FS does a good job with the primary physics of flight. A shallow banked turn (< 30 deg) will require little additional AOA to remain level in the turn. The 404 table in the air file controls the lift vrs AOA. To see what is precisely happening, I suggest obtaining the AFSD utility by Herve Sors, which monitors a plethora of goings on in real time.

To make it less stable reduce the values for Roll, Pitch & yaw stability in the aircraft.cfg [flight tuning], I find a value of 0.5 suits my aircraft normally. As for yaw in a turn one needs to play with the .air file - Block 1101 & scroll down to Cn_da. There may be some others that might need a bit, but try those first.
Also do not forget to change the realism settings........
