Zor brought up that old thread, it's true, it just went on and on without one firm answer. Loading is measured as your wing area and the weight of the plane, that's why the chart is so easy. The wing span is measured tip to tip and the fuse isn't measured in. Here is an 80 span plane with a big fuse, the fuse isn't counted in the span or area. You make up your own mind. It is a one piece wing so when I remove it then it's still got the same span and area. My thinking about wing loading is, it is what it is and I don't worry about it. It gives you a general idea of it's stall speed and landing speed. Heavy small wing warbirds have a high wing loading and they tend to stall faster at lower speeds. What you going to do about it other then fly and land a bit faster.
