OK that definately looks like fun, nice find! Great question on normal skeet bird speed. Despite spending many years busting clays I had to check. Best answer I could find is that there is no "official" speed but normally they cross the center of the field around 35mph. So 50mph on a high deflection crossing shot with a curving flight path would be pretty sporty! I want to know what that little drone is made of as it definately holds up well to fire! Guessing they restrict shot size and make sure no one gets funny and fires steel shot at it
