I had combat trim on, but I mostly fly with it on so I don't think it can be that.
Tequila -  I think we are talking stall limiter now that I think about it.  The reason it was on is because I'm not used to flying the 38 with it off, and I knew if I were to try this I would spend more time in flat spins than actually working on the maneuvers.  But that does seem to be the case anyway.  Like I said, its not just the 38, I had the same behavior in the jug.  
Talking to those guys is a great idea, and I plan to investigate further, but I think that there should be a setting to enable/disable stall limiter in the TA.  If it is indeed for teaching new pilots, the stall limiter is a nice thing to have.  And I checked several times, unchecking it, then rechecking it, and the plane behaved the same both ways.
