Hi Sid, I fly at a full scale airport (no tower, uncontrolled) and we use the spotter system to avoid full scale aircraft. But, I have found that by having a handheld aircraft radio I can hear any full scale calling out their approach long before I can hear or see them. This normally gives me plenty of time (like 5 minutes or more) to land and get clear before the full scale is anywhere near the field. They aren't expensive ($100-$200) and are extremely useful IMO.
