I count 4 longerons in that fuselage.
My eyes have not been calibrated recently. But I would say the Piper PA-15 plan are about the same. The thrust line is marked on the fuselage plan and the wing attach points are parallel to it. The angle on the stabilizer is not marked but the forward tube is lower than the rear being supported on a bracket under the top cross member while the aft attach point is supported on a bracket over a top cross member. (While the longerons are sloping down toward the tail at an even greater angle.)When the fuselage is leveled per the plans, the stab is -4 degrees. In the leveled condition, the wing attach points are level as well.
It's easier to visualize with diagrams with arrows and labels and twenty-seven 8 x 10 colored
Glossy photographs with circles and arrows and a paragraph on the back of
Each one explainin' what each one was.
"And there wasn't nothing (we) could do about it, and the (OP) wasn't going to look at the twenty seven eight-by-ten color glossy pictures with the circles and arrows and a paragraph on the back of each one explaining what each one was to be used as evidence against"... changing the factory specifications.It seems that this whole discussion has become a case of blind incidence.

In reference to what? Longerons? Chord line? (Piper people like to reference things to the generally-flat bottom of the airfoil.)Did a little research. The Wag-A-Bond is indeed intended as a clone of the Piper Vagabond.
That said, the Vagabond engine offset is 4 down and 2 right. For whatever that's worth.
By comparison the Piper Cherokee has 3 down and 3 right.
No. Not always. It's decided by the designers.Engine offset, wing incidence, and tail plane incidence, is determined from the centerline of the aircraft.
As for my statement, perhaps I should have used the term "Datum Line", rather than "Center Line".
Please post a credible source for that.
Stop deflecting.I find that amusing, sir.
