Reversed mach tuck

[HWasp]

Edit: See second post! Also proper thread name would be weaker mach tuck instead of reversed.

 

 

At high mach numbers (0,8+) plane developes nose up tendency instead of nose down. In previous versions (no idea when it changed) the behaviour was correct: nose down due to mach tuck.

 

 

Please investigate

New test

Further investigation with track and screenshots to be accurate:

 

 

I've done a high altitude test with the following result:

 

 

-at approx. M0.6 elevator neutral

 

 

-between M0.7 and somewhere M0.85 relatively strong nose down elevator is needed for level flight.

 

 

-Over M0.85 there is less nose down elevator needed. But it is still nose down elevator

 

 

So altogether some mach tuck can be felt, and in the right direction, on contrary to my previous post, but it seems much weaker than in a previous version (really unsure when it was exactly).

 

I did not find anything regarding this behaviour in the DCS flight manual.
