Has anyone tried the sig easy hinges? They claim they are the greatest thing since sliced bread. What results has anyone had using these on sport ships
No no no! WAY too stiff! Use cloth or sewn hinges on thin surfaces and pinned hinges on thick enough surfaces.

p.s. I violated my own rule by giving advice without explaining why. The reason they are OK on RC planes but not on CL is that on an RC plane, you have a servo with a fair bit of torque in all conditions. As long as the torque is sufficient to move the control, it will move where you want it to. On a CL plane, all you have to move the controls is the line tension, and in light line-tension conditions this can be insufficient to move the controls against the combined effects of the hinge moment from the slipstream (deflecting the controls into the airstream takes some torque, considerable in some cases) and the stiffness of the hinges. If you have a fixed control handle position, the total deflection of the controls changes as the line tension changes, causing changes in the effects at the airplane.
This is all very important stuff. Paul Walker, crowned the National Champion about a week ago for the 11th time, was talking about control effort effects in his NATs thread entry.
