Dave,

Funny that because I used to own said Thunderbirds CF. Of the dozen flights I had on it I can assure you it happens! Even so in that the last time I watched it fly at CJ it was doing it!

Basically what happens, in a clean flight mode at moderate speeds, during banking, be it left or right, the nose digs into the corner. It is visually obvious to a keen eye. I don't believe it has anything to do with CofG, it is just an aerodynamic flight characteristic of the CF. I know for sure that the UF doesn't have this tendancy. It wasn't just my CF that did this.

Before the 'dissers' come out I think you'll agree that both 'SE' and I have a reasonable amount of experience in such matters.

Just my thoughts/experiences.
