My Kr-2 has Diehl skins.  "Power at idle" stalls at about 900 lbs. occur at 
50 KIAS.  Stalls are proceeded by enough shaking and shuddering for me to 
notice.  The plane is controllable throughout the stall and will recover 
even with the stick held full aft.  The plane has no tendancy to drop a 
wing.  Of course it just stalls again if no action is taken, and each time 
it stalls, the pitch down is greater and so is the pitch up after recovery. 
I have held the stick full aft through about 3 or 4 stall and recovery 
cycles with increasing pitch excursions.  I'm guessing these cycles took 2 
to 3 seconds each, but I really don't have a clue how accurate that is.

Does the fact that the Diehl wings are longer (and tapered over this 
additional length) reduce the MAC a small amount and therefore reduce the 
C.G envelope?  Even if true, perhaps it's a small amount.
