I've been using Reflex xtr for pattern practice for some time now. There is an Integral that can be downloaded from
www.rc-sim.de that flies very well. 0ver in the pattern forum there's a group that uses Phoenix.
I've found the simulators useful for developing muscle memery when learning new manuevers. To do the whole pattern is more of a problem since it is difficult to have a perspective on the flight path and airplane position relative to flight line. What would be nice is a simulator that allows you to draw grid lines in the sky and position objects that you can to use for reference. Reflex has one cartoon type scence that has grid lines but if you fly too high the plane disappears.
Some simulators allow you to create your own scenes, but it is not an easy process.
Hope this helps.
