Recently, the local state park hosted a model RC airplane meeting, so I stopped to shoot a few photos (ok I shot 2200 photos).

There were all sorts of scale model flyers, including this Mig 15 jet. And yes, it was an actual jet aircraft that was incredibly fast and agile. Here's a shot of some of the aerobatics as it climbs and banks into the cloudy sky.
