I was looking at the manual online for the Aeroworks bipe when I got to the end there are some setup tips from chip hyde that sound pretty good. I figure these will work with any ultimate, but specifically I was wondering about his procedure for checking for a tail heavy condition. Pull to a 45* upline and roll inverted and it shouldn't take much down elevator to maintain the line. If the plane goes to the belly like you were giving it down your tail heavy. You think this is valid for any ultimate? or for any plane for that matter? I don't know what mine will do in this situation but I'm going to try it next time out. I had another guy at the field check my ultimate and he said it seemed a bit tail heavy, and that he's had several of his own. (he was flying one at the field that day) Mine does balance within the recommended range, but aft of the recommended point.
