Something completely different...
Pico Jet pylon racing. We do this once a month at our club. It is very silly and stupid, but very funny and completely different from what we usually do.
The course is only about 30 yards long or so. If you dont have flags to fly around, its not important, we have flown around a traffic cone at one end and a sun shade umbrella at the other. With the course so short it keeps it interesting.
Usually at least one Pico Jet gets destroyed each race, but no matter they can be fixed with a bit of epoxy or cyano

. And they are so cheap to get into the air on standard setups.
Basically you can not take racing a big hunk of foam too seriously so it is just a laugh.
