Texas has no sales tax on airplanes. On the other hand you would probably need to demonstrate residency in the state that you registered it unless you formed a corporation and that is too complex for me.
California needs the revenue!

It is usually a great idea to keep it simple and honest.
If I were to go to a purchase and find that someone was in a grey zone on the finantial end I would probably wonder what they might not be telling me about the plane that I would need to know.
