I finally put two plus two together and realized that my near full nose down trim in cruise was the cause of my slow cruise speed. Cg does not appear to be the problem. Low speed, below say 120 ias, seems fine. But 130-145 results in nose down trim near the limit. It seems to me my horiz stab is not producing enough lift at high speed cruise.
Any one else have this problem?
