I flew my new Great Planes extra 300s (40 size) on its maiden flight today. This is my second kit and my first test flight. Almost lost control because my hands were shaking so badly. I flew it around the field four times and brought it in for an uneventful landing. I did notice that the rudder was very unresponsive. The slower the speed the worse it seemed to be. This is my first aircraft with a great planes servo saver on the rudder servo. I'm thinking the springs are not adjusted correctly. Before I adjust them I was wondering if anyone knows if there is a measurement or technique I should use. I do not want to compress them to much.

Thanks
