Basin Bum hit the nail on the head when he asked how many people even reallize that there are models that cost $3000.00 and up. I don't think there should be a monetary limit on what one can spend on any aircraft but after you pass the range of 7 to 8 hundred bucks you have to take into account that some dummy will do the wrong thing either uninentionally or unknowlingly. Maybe this is the only form of relaxation he can afford and it's very little at that account a wife and kids, car payments, mortgage etc. To expect that poor guy to pony up 3 grand and up is going a bit far. Before he even started flying at any field he should have been throughly briefed and told of the possible consequences. For a moderately priced model he might be expected to pay what he can afford monthly. For the big boys there may be nothing he can do even when he sincerely regrets his lapse of acceptable RC conduct. If the guy is just sloppy and careless and even snotty about it he can be firmly denied the privelege of flying at your field. We had one like that and advised him to try any other hobby he could come up with as long as it wasn't RC. He was also advised that he was now in the position of having anything he flew treated in the same manner as he had shot down other aircraft. I have no idea what he does now for a hobby but it sure isn't flying RC.
