I've had G3 for about a month now and have a question about trimming out planes - flight trim not color scheme. Will a given plane require different trim settings at different times? Sometimes, I can't get a plane trimmed at all - they will just fly in circles no matter what I do. I have tried re-calibrating the controller, but that doesn't change anything when the planes are acting that way. I have version 448, which is the most recent. The only thing that will fix it is to exit the program and restart. Is that normal, or is something wrong with the interlink controller?

That sounds interesting. Next time, why don't you unplug the controller and plug it back in after 15 seconds or so. Then select new interlink device.
