The SAE Aero Design Contest is an international RC aircraft design challenge. One of our local RC fields (http://www.fwthunderbirds.org/) hosts this. I have been asked if we would like to set up a tent and watch the competition while we yap about drones! This is a link describing the event (http://students.sae.org/cds/aerodesign/west/). The Tyler Maker Faire is also on this day so you get to choose!
Bring your birds, a comfy chair and a video camera as there will be spectacular crashes!
