Unfortunately, the scale of the 500 series kits varies by model. The determining factor is the largest size model that can be built out of the standard balsa sheets that fit in the box. Most of them have a 16-1/2 inch wing span. You will have to divide that by the actual wing span of the aircraft modeled to find the scale.
