I believe what was meant was that this was already discussed and cleared up on the Ru side. I read the same thing on a separate English forum that there is a misconception among us users about the flap panel, ie. people think its 3 buttons that only do 2 settings versus the reality of it being 3 buttons with 3 different settings as per some Mig-29 manual or documentation (Up, TO Flap + TO Scheduled Slats, LDG + LDG Scheduled Slats rather than what some assumed was just Flaps Up or Down with an unused middle button).
It's more a comment on how the misconception above has been explained on the Ru side, perhaps worth making a note of this in the manual later down the road as it is both a very relevant system and of course just interesting technical knowledge (if its correct of course)!
TGP14's post in DCS MiG-29A Flight performance and air drag seems weird was marked as the answer
