Colin,
I think I know where the confusion is.
Angle of incidence is the relationship of the chord line to the longitudinal axis.
The chord line is the imaginary straight line joining the leading and trailing edge of an airfoil.
On the USA 35B airfoil of the Cub, the chord line relationship to the lower surface of the airfoil is approximately 1.5 degrees.
So when it is said that a Cub's angle of incidence is 1.5 degrees, that would place the lower camber of the airfoil parallel to the longitudinal axis.
Look again. This is about a Cub not the drawing.I know I am a bit dense, but the last sentence does not make sense! The lower camber of the airfoil (lower surface of the wing) is not parallel to the chord line. You can see that on the cartoon. What am I missing?
It is like Crack, I just keep wanting more. I don't always know the science of why something works, I just know it does in the seat of my pants.

"So when it is said that a Cub's angle of incidence is 1.5 degrees, that would place the lower camber of the airfoil parallel to the longitudinal axis."
My latest wings from Jay are 1.5 from memory but i measured them to the window/ door sill and didn’t get any difference. I’m a bit confused. I’ll check with jay again. The fuse is standard like yours I think.
It worked on my Cub. Been flying with it since Mark first started with it.
You cant have it back, Mark.
Yes.By "lower camber of the airfoil" you mean bottom of the wing. correct?
