There are a lot of factors. For a given wing loading, the wingspan will determine if it is heavy or not. I have heard that someone has worked out a formula for cubic area instead of area. I don't know the details, just remember, as the wingspan increases, the same wing loading will appear lighter to fly.
how do u calculate the max. wing loading of your rc planes?(due to wat designs issit the angle of og the wing or???)
THis is not exactly correct. A 40% plane can have a wing loading of 35-40 and still fly good. A .25ci plane will be a brick at 20.

The wing loading of an airplane should be less than 30 for the plane to fly good.
