Thanks for asking. It has jarred my memory and I now remember changing the tail-feathers to make the airplane more responsive as suggested by my trainer back then. Once I enlarged the rudder, it flew a lot more responsive and stable. It definitely changed the tail moment. If you had not noticed, I may have never remembered making the change. [8D]

The Tri Squire was popular in Class I. The rudder only guys installed a larger rudder, removed one rib from each wing panel and installed a hot .35.
