Default reverse ground effect

Anyone else noted that the MiG-29 suffers from the same 'reverse' ground effect like the F/A-18?
It's not as noticable as in the F/A-18 because the MiG-29 is rather pitch sensitive.

I did notice it, was really annoying, but seems like it is gone in the latest open beta!


Edit: Seems like it is gone from the Hornet as well, so that might be connected.

Tried the latest beta and can't confirm that the reverse ground effect is gone.

Erm ... what exactly do you mean with 'reverse' ground effect?

I have experienced the following yesterday:
A sudden drop to the runway from a few meters above at (+/-) constant airspeed, but I expected a smoothing of the flare due to the ground effect.

Is it that what you are meaning?

Reversed ground effect as in it will suck you down instead of "push" you up.

ok, then I got BBRZ it right, thanks!
So for the programmers: the ground effect must be added, not subtracted from total lift ;-)

There was a thread a little while ago where it was shown that certain planes with low tail planes pitch down in ground effect. This happens with the Hornet also
Mentioned here https://forums.eagle.ru/showthread.php?t=243913

So has anyone found a logical explanation to the seemingly reverse ground effect for the Mig-29, or is it a bug?

No explanation but the manual, concerning what is done just prior to touching down following normal proceedures, does say that: "The movement of the control stick in the process of leveling is significant: from neutral to almost completely 'into yourself'." So it sounds like you are definitely counteracting something at that point. You certainly don't need to be that aggressive in the Su-27, for instance.
