I've been helping teach the Senior Airplane Design Class at the University of Washington for the past two quarters. Today, the valiant class took their radio control model of their class project to Whidbey Island to fly it for the first time. They have designed it, tested it in the wind tunnel and today was time to savor the results.
Well, it was a fabulous day, but without the totally fabulous ending.
Here's the critical video:
Now, this was a difficult design - very squirrely and even in the hands of an expert RC pilot, it was going to be difficult to get the thing in the air and back safely on the ground. The pitch up that led to the crash was somewhat predictable from the wind tunnel data.
Still, it was a great achievement...
