Wing Incidence

[Appowner]

Anyone know off hand what the wing incidence of a Cherokee 180 is? In degrees. And what reference line is used? Typically the thrust line is the reference but we all know how those things work.

As some of you already know, I'm the guy building a 30% scale RC model of a Cherokee 180. I'm using the same airfoil as the full size. The plans I have show a 2 degree angle for the wing but somewhere I seem to recall the full size being 4 degrees. That does however sound a bit much to me hence the call for help.

Thanks all,
Kevin
