Is there any way to get small GA planes to keep the hell away................
Whoa.
The answer is "yes."
First, what you described indicates that there are not enough parking spaces available for GA traffic at the airport in question. Try adding more spaces of a smaller radius!
Second, if you haven't already, I recommend getting familiar with the RAFCAD method of assigning aircraft types to parking spaces. AI Traffic Mover is a good program for editing the aircraft radius and resizing gates. It seems like a complicated program at first, but it's incredibly handy when you get the hang of it.
Here's a link to a recent thread about the RAFCAD method:
