If you don't mind driving a few miles you might visit the Ocala Flying Model Club which is near Belleview.
They have an excellent facility. I've driven out on a couple of Saturday mornings to watch them fly.
Some of the flying is more robust than the electrics that are allowed at the Polo Grounds because they fly fuel aircraft. Sometimes you can see helicopters as well as fixed wings.
The field is very impressive. The paved runway is so large that they occasionally have a full sized airplane approach to land before they realize it is not an actual airfield. On the home page scroll down for several views of the field.
