Well crasher, I have had some good luck with the edge. I like the way it flies and is very smooth with me. I had some of my friends try it and they said it was tail heavy, even with the OS 70 4s. So I tried to re balance it to suit them as I am just learning the 3d stuff. Now It flies much smoother since I balanced it to 2 1/2 inches. However it is not as crisp in the 3d department. Guess the tail heavy bit is a trade off there. Hope yours is flying as good as mine.
