I guess the best thing might just to be to take a few key things from this post and try to learn the rest through experiance. With the aerobird I wouldn't suggest very much wind at all! given its tendency to spiral in when the stick is held over for too long, if you gain lots of altitude and you run into heavy winds, it is very hard to turn it out without ending up with another problem. I just wouldn't fly the thing with any wind over 5mph or so. Keeping in mind that the surface wind can be significantly slower than it is 50 ft into the air.
