Go back to your hole where you belong. Show me the EM chart of the 29 you are speaking of - actual hard data not some youtube video. Most airshows arent flown at "corner speed" or max sustained rates etc. let alone the same conditions or comparable weights. We have data for the 29A (9.12) from the GAF manuals and those match DCS reasonably well. 9.13 (29S) should have only slightly more max AOA and controlability.
Again, apart from youe YouTube video please do provide the performance charts or any factual reference to form a well-educated, fact-based and rock solid opinion.
EDIT: And OF COURSE it's your own video. Nice evidence crafting my dude.
