Actually, this is a common misconception, but there is no such thing as an
inside wing stall on any turn, unless it is a very shallow turn in a
pre-stall configuration, and the pilot suddenly applies aileron opposite the
turn, in which case the inside wing will stall first.


Expanding on my previous thought process. Execesive Overbanking
tendancy may be the reason that some aircraft won't (or at least are
difficult to) stall the inside wing. The 2-33 for example the
overbanking tendancy is so bad that it may run out of aileron to hold
it in a constant bank turn at low speed. This requires the pilot
either lower the nose or apply opposite rudder to prevent the turn
from getting any steeper, both of which will lower the AOA on the
inside wing. If the pilot allows the bank to get steeper the airplane
runs out of elevator authority and the nose drops on its own
increasing the airspeed and also lowering the angle of attack.

As is almost always the case moveing the CG back will give the
airplane more elevator authority and a better change of being able to
stall the inside wing.
