What kind of wind will these helicopters take? Need something for winds 3-7 mph and something that flies pretty stable. I'm trying to deceide between this one and the Corona.... I know the Corona will take a little wind. I've got the Vectron UFO to fly indoors as I don't want to break any blades on the XRB types of Helicopters. The price of the Corona all decked out is upwards of 1,000 dollars but this one at 200$ might be just as fun. Also would the transmitter that comes with this model work with Reflex XTR?
