I have been having fun with a used Avistar lately. It's a fun little airplane with a great inverted flatspin. The only thing I really don't like about it is that at high speeds when you give elevator it likes to "balloon" up to a very high AOA very quickly. While this makes for snap roll I am worried that any engine bigger than the old worn out LA 40 on it will snap the wings in half if I give it too much elevator at speed.

Is this just a semi-symmetrical trainer trait or is there something I can do to prevent the "balloon."
