I had just visited the park where this happened to watch because i love this hobby (prior to the incident) and there really should be more safety precautions taken in fling fields, because these helicopters are only 40-50 yards from the spectators, and there is nothing stopping these things to do what it did to that kid
Last year I went to a fun fly at that field. A lot of those guys, including Roman (who I met), were pretty much flying right in their faces and on the deck the entire time they were flying. Even that day there was an incident where another guy was flying above his skill level on the deck, the tail smacked the ground and the heli started pirouetting out of control. Well it flew right into the pit area and hit a car, and the shattering glass injured somebody. And yet immediately after there were still about 6 or 7 guys at a time flying next to each other on a field that's about 500 feet wide without any concept of staying in their own flight box. Since that day I hadn't been there again and I definitely am not going back there now.
