I think the hawks and the vultures are safe, I can assure you that even the slowest buzzard can out manuever any RC plane. But I love watching people's knee jerk reactions to their perception of other's actions
The TWRA has been very successful around here at "re-introducing" wild life and improving deer populations. Now we have so many hawks and coyotes around here that you very seldom see a rabbit anymore, quail are practically non-existent, red and grey fox are a very rare sight anymore, and you can't drive down any road or city steet at night without a real good chance of hitting deer.
Twenty years ago things weren't this way. There were deer, a few hawks, and the occasional coyote, but nothing like we have today. When I was a boy, you couldn't walk a fence or a tree line for more than 200 yards without scaring up a rabbit or a covey of quail, but not today. They're just not around because they've got too many predators now.
If it were possible to take out a hawk or coyote with one of my planes, I can't say I wouldn't be tempted to remove a few. I'd prefer to have a few less of them and a few more rabbits and quail. Of course, if I did this, it would be at the privacy of my own property and not at my flying club field, and I probably wouldn't brag about it here on RCU.!
