I dont normally post much but i do read alot what goes on here...Today I am walking my dog around the local park where kids and people come to visit. And this young boy (20 ish?) brings out a brand new trex 550 and starts to try to hover ! He did not have control, it was all over the place. There were kids nearby so i came up to him and told him he should not do that. Well i know i might have sounded abrupt but I was concerned. He abused the hell out of me and told me to f... off. He even raised his fist at me. This surely is a catastrophe waiting to happen! With idiots like this our hobby could be doomed..Do you think we should mind our own business when this sort of thing happens?
