could not get the thing to fly without almost full throttle. Took a good look at the set up and realized the fly bar blades were set the wrong way. In fact as the main blades were trying to fly,,, the fly bar blades were trying to set it back down. Anyway I set them up the right way (thought out of the box was supposed to mean it was able to fly out of the box) and,, well to my surprise gave it the same amount of throttle and the thing took off like a rocket! straight up about 150 ft, ran into a tree, broke the tail gear, hit the roof of the house, bounced off and headed for a power pole,, hit the transformer,,, and headed straight for the neighbors truck. Thank the good lord miss the truck about 4 ft and that was about it. Broke the skids, tail blade, and one main blade. Not bad for such a crash and burn. Word to the wise,,,, check the Eagle 50 out before ever trying to fly the thing. Don't think ready to fly out of the box really means it. Cost me a bunch.
