well - I don't know what weight ranges are on each of the models you have - .
The problems on all of the kits I have seen are directly related to high wing loading.
Loading is -on the ARFS - typically at the max for flying most aerobatic stuff.
On a Cap - it is easy to get the loading too high.
On a " Stinger type "- the loading can be a bit higher.
I see -typically - 1000 sq in ARF models --with wing loadings in the 30's -
tho these will fly --and can be coaxed into large open maneuvers -- the wing loading on a GOOD 1000 sq in aerobat is much better around 22-25 oz ft.
These setups can stand much more yanking around --
I stand by my comment- most are simply too heavy --and many of the heavy ones are tail heavy -
and most of these are ARFS
