I've never hit a bird with a R/C Plane but I have had to walk down to the end of the runway so the geese (sky carp) would leave and I could fly. one time they came back during my flight and I had to land short and veer off the runway and nosed over to avoid getting into them.

I wouldn't eat a goose at gunpoint so I'm not going to ruin my plane with one either LOL.

Another time in San Juan National Forest while flying my F27c stryker about 10,000 ft. I had a raven try to take out my stryker, wich turned into quite an argument. I didn't hit the raven but I won the argument! I think the full throttle whine and the speed won the argument for me!
