CafeenMan, the SR Eindecker is pretty fairly responsive with ailerons. I rolled it but you need a lot of air under you! A couple of weeks ago I got it up but we had one of those days with sudden gusts of wind and a few times as I was making turns the wind cuaght it and flipped it. It was hairy but the ailerons brought it under control pretty quick. I found that if you have any kind of wind you should use rudder as well as aileron in turns.
