Thanks Dick...
The Tribute will pivot on a wing tip during a hard rudder turn...but I need to feed in substantial opposite aileron to keep it from flipping right over in sort of a snap.

Think I'm gonna remove either the top or bottom SFG's (one at a time ) to see what happens.
I'll let you know.

I had a Tipo for a little while, in the early 80's, so I know what you mean there
