Set the Eternity bottom wing at +5 degrees. The top wing should be between zero and +5 degrees depending upon how the plane performs in knife edge flight. My Eternity required a 1/32" shim above the trailing edge of the bottom wing.to achieve +5 degrees incidence. I'm still working on the top wing. With the trailing edge of the top wing touching the fuselage, my Eternity requires a significant shim under the forward wing hold down screw in order not to have negative incidence in the top wing.
