Bill,

I suggest you try = adjusting your=20 rigging.  Your rudder trim and flap down position for = starters. Make=20 sure you aren't leaning on a rudder a little.  On my bird, there is = a=20 permanent rudder trim tab and the flap up position has the trailing = edges=20 slightly mismatched.  You may try this in order to get a more = controlable=20 stall.
 
I have always been able to avoid a spin = entry by=20 quick use of the rudder and would never deliberatly spin.  Once, = while=20 pulling several G's and maneuvering for a quick landing, I ham fisted a = little=20 too much and got an accelerated stall -- the plane started an = accelerated spin=20 entry.  Wake up call.
 
Don't ever let the plane stall = inverted,=20 especially if you have the small tail.  It does not want to = recover at=20 all.  I lost 4000 ft and only got it to recover by starting an = inverted=20 spin.
 
Fly safe.
