Ya funny.. same thing happened to me. I just happened to be in an aircraft hanger as I was going to hover it for our mechanics. I was spooling up and gave it a couple whips and "SNAP" for no reason... It threw a blade. All the maintanance guys checked it out and the rotor had mold defects. I saved mine. A small in the base of the blade that snapped. Small hollow hole at the base of the blade if that makes sense. I am glad it didnt hurt anything or anybody. I will only fly it outdoors right now after having that happen. I think they have a cheap supplier for rotors ..lol An other thing. There is no way they test fly these things before shipment. My flybars were 45 degrees off. the paddles. One lock collar was stripped,the set screw. The tail rotor motor was not tight. The tracking was not that far off. The pinion gear was totaly clean as have never been run.. haha .. Oh well. Company support has been good so far. I'll let you know in about a week. I know one thing about this heli. If you can fly it around like its nothing than you can fly any rc heli. That comes from experience. I am just kinda getting into this heli and am going to post as it goes. The thing acually flies nice for its size. It hovers almost hands off once you get it out of the rotor wash. It has done good in wind so far. Actually very good. Its like having a cute little dog that doesn't crap everywhere but gives you a nice challenge.. .. more to come... -greg
