I was dog fighting with a couple of crows a couple of weeks ago. I was flying a home built 3D model with a 36 inch wingspan when a couple of crows attacked it. I did a tumbling maneuver\reversal and then started chasing them around the field. The weren't expecting that. Crows can't do vertical, so they were a little outclassed. Of course, I have no idea what I would do if I actually caught up with them. I really need to put cameras on some of my models.
