I love this program. With the PIC interface, it is a really nice simulator. All the models that are included with the program seem to fly realistically, except perhaps the stall doesn't "feel" quite the same.
I notice that the models I have downloaded from various places vary widely in their realism. I guess the parameters that define how a model flies can be abused a bit. The most obvious example of this is 3 different variations of a model called "seduction." I guess the modeller wanted to push some of the settings to the extremes and see what would happen. These fly like something out of a cartoon. You can throw full rudder and take off and fly sideways in a circle. It's fun for a minute or two, but I really prefer to fly realistic models.
Keep up the great work!
