Gene, I would love to see you ahead of me in the standings

Pattern planes generally have a fuse that is longer than the wingspan (helps the plane to track very straight through a maneuver). Symmetrical wing, either shoulder mounted or mid wing mounted. Some of the longer 3D planes are known to do pattern stuff pretty well so long as the rates are turned down (10 degrees deflection is all you need for pattern) like the H9 Showtime or something.

A plane for a .91 four stroke is a tough call for me with my limited experience. I immediately thought of this one but not sure if it's just too big of an engine:

This plane has a lot of good reviews. I would probably recommend asking in the pattern forum though, you'll get better answers there. I will think about it in the meantime.

It is my pleasure to help anyone get involved in pattern flying. Please PM me if you want to ask me questions personally.
