As in boating and full size airplanes, it's the responsibility of the faster, more maneuverable, more experienced vehicle/operator to avoid slower, less maneuverable, less experienced vehicles/operators. In other words, they are supposed to stay out of your way.

If their flying is reckless, and endangers people or property, then it's a violation of AMA (and possibly club) rules. Address this to the club officers, starting with the Safety Officer.

I'm one of those pilots who like to "show off" for a crowd. However, I will not fly if there are novices in the air. I respect their air time, inexperience, and desire to fly. Waiting until they land to fly gives me more clear airspace and eliminates the possibility of scaring or intimidating a newbie or having a midair. I can also watch them fly and possibly make suggestions or offer help.

As a last resort, enlist a spotter to help you stay out of their way.

Unfortunately, everyone has one but some ARE one. You'll find rude air hogs in just about every club you go to. Try to address your problem to them first (in private). It's possible they don't realize what's going on. If that doesn't work, then a chat with club officers is in order. If that fails, look for another club. Don't give up the hobby for the sake of a few idiots.
