yesterday i had my raptor up and running for the first time i had it hovering about 5 feet off the ground, perfectly i was getting the hang of it. then it happenned, im assuming the bolt that holds the throttle lever in place came off, the raptor just took off high in the sky. at first i did not know what the problem was i thought my batteries were low and the receiver was not reading the commands on the radio. oh by the way this all happened in my backyard. anyway i found it 3 blocks down un top of a roof of a house which i had to get permission to get it. got it took it home. broken parts to many to list. thank god i still have a backup heli. my raptor came 90% assembledand i dont think who ever set it up used locktite on that bolt. so if you get a heli 90% assembled remember to make sure that everything is tight before flight. good luck to you all and happy flying
