Just witnessed the Revolution 3d plane fly outside and it fly's beautiful. it resembles a pattern plane to the fullest. The rolls are responsive and axle. Tracks straight. He extended the nose a few inch's , which looks even better and only adds to the performance. There is some flex in the wings , but not bad considering it weighs around 10 oz's. It looks like a great fun plane to fly and maybe it will inspire more people to scratch build. Thanks Bryan and keep up the good work. Bill
