I've only had one issue. After a few months I've developed a few stress cracks on as many arms. Doesn't seem to affect it. Maybe it has released the stresses. I plan to buy a new shell and rebuild it myself. Sounds like a fun day to me. I hardly worry about my drone as far as functionally goes anymore. I love it. I can live with some stress fractures. I love taking things apart and now I have an excuse. So I guess I haven't had zero problems but I consider this minor considering what it does as a whole.
