RE: My First Experience with Low-Winged (Modified AA)
A low winged aircraft is harder to control but you added a swept back
wing into the mix also. Make a low winger with a straight tapered wing
and you'll gain some of that control back into the turns. The swept back
wing is why the CG is 1/2 back the leading edge- causing the turn dives.
Like you said it's what you desire in flight characteristics and the swept
back wing can give you some crazy stunts.
The wind also might be causing some mayhem. One plane I flew on a
calm day was very responsive. On a windy day the same plane constantly
was being pushed into the ground as it came out of the wind. It had no lift
at all out of the wind. The next calm day it was back to flying normal again.
