"If it flies,**** it fights." Anyone who brings a UAV to Flight Club must enter it in combat. There are no rules for what a pilot can attach to it.
"Knock the ****other guy to the ground." After a crash, the grounded drone's operator has some time—at least until the crowd gets antsy—to patch it up and get it working.
**"Two drones enter, one drone leaves." **The battle ends when one combatant has sustained too much damage to be revived.
