Back to the SHOT DOWN SCENERIO.....All RC flyers at a clubs field don't know better and can't pay for $10000 planes. So I hand it back to you , the choice is yours, fly knowing this and suffer the consequences or just find some where else to fly which suits your style of aircraft. Whether $1 or $10000.
You could also look at it from the other hand. If you know that you can't afford the price of the plane that's flying with you, then wait a second for it to land. The airspace doesn't just belong to the people that 'don't know better'. They have just as much right as you to enjoy flying. They and you paid your dues for equal time. It doesn't matter if your plane is $1 or $10 or $1000. If you are in the wrong you should do your best to make it right!!
