Peter yes the wing loading has a direct affect on the stall speed of the aircraft. Increase the wing load and and the stall speed will increase. There are other factors affecting stall of course chief among them is airfoil design. Weight of the aircraft is not the only way to increase wing loading either. A steep level turn will increase stall speed considerably. In the full scale world this is called an accellerated stall but applys to our models just as well, sudden gust or turbulence will also increase wing loading and stall.

Now what is basic static wing loading? It is just the total wing area usually in square feet divided into the total weight (usually in the case of model aircraft in ounces) to render the wing load. For example a typical trainer may frequently be around 18 to say 24 ounces per square foot. Many types of model aircraft may be much lower or higher than this howerver.

Wing loading figures are often given in catalogs and such and by taking note of these figures you often may get an idea of how an aircraft will fly, fast, slow and how well it will handle turbulance/wind Aircraft with heavy wing loadings will typically handle winds and turbulance better.
