Following the popularity of Robot Wars from a few years ago, it only makes sense that someone, somewhere, would pit quadcopters against each other in a battle to the death—or at least first crash.
Sure, these events might have been cooked up to promote an extra-tough quadcopter airframe that's being funded through Kickstarter, but does that make this indoor aerial combat any less entertaining? Absolutely not. Would you buy tickets if a similar event came to your town? Without a doubt. Maybe the real money here isn't in airframes. [YouTube via IEEE Spectrum]
