Every field has some flyers which are unsafe or wild. When one of these guys at my field go up in the air, I immediately land my plane. I won't subject my plane to someone elses erratic flying style.

Considering the circumstances you claim, I would sue the guy who broke the pattern and caused the midair. You suffered damages by his negligence or inability to control his plane. When you bring that to court, you will win. Nothing, including this hobby, is lawsuit-free. The club can do nothing for you ... but the courts can!!

Yes, it was an accident. But it sounds as if the other guy was at fault for the accident.
