Personally to me as an RC flier.....I tend to fly at the 40-50 mph cuise range...........so a lighter wing loading is my preference............also, I tend to "float in for a landing"(minimal power or power-off approach) versus "fly in for a landing"(power on approach) and so heavy wing loading aircraft I avoid. I have been flying RC (glow in those days as electric was not an available option) since 1979 but I still tend to "float in or glide in for the landing". So for a modeler......wing loading as a criteria in choosing/selecting an RC aircraft is very subjective. There are those that can land smoothly a heavy RC turbine jet but I am one of those that would stay away from heavy wing loading RC aircraft because of my tendency in floating in for a landing. 'Nuff said.
