Hi Steve, I'm about to fly mine, what do you mean by the stock incidence?
Do you mean you didn't change what it is after you bolted the wings on?

Thanks
Daniel

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.

Oops.....my mistake. Yes.....it is +.5 degree, not 5 degrees! I'm still waiting for a low wind day here in the Midwest to maiden my Eternity. I had perhaps a 3/32" gap between the top wing and the top of the fuselage with the wing sitting on the struts. I ended up covering the fuselage wing seat and bottom of the top wing with plastic wrap and placed some Hysol epoxy in the gap to form two custom fit shims. My top wing is currently sitting at +.1 degree incidence. I'll make further adjustments, if needed, depending upon how the plane flies in knife edge.

Yes. 0.5 degrees is correct.

I am installing the stab fences which were supplied with the kit on mine so I'll see how it goes. I'm thinking that it will improve tracking through corners a bit. I'll post pics once I get them on.
