Just wanted to say, I've been flying mine since the 26th of July. I have 4 batteries. 1 came with the bird, 1 was free from Autel, and I bought the other 2. I have 18 flights logged on each battery. At an average flight time of 20 minutes (estimated ) per fliight, that's 24 hrs in the air. With all that said, I've only had 1 issue which was my own fault. I was doing a way point mission when the dreaded composs interference in flight happened. I was flying in my neighborhood ,where I have flown before when the bird went spinning, shooting a crossed the sky (outa control). There were several warning from the app that I missed. I was to busy taking with the neighbors about the x star premium. I saw the warnings when I reviewed the screen capture video. I was able to save her with the pause, then rth buttons but it scared the **** outa me. So for me ,this bird is well worth the money. I've already ordered another one for backup. Quad copter only. Got a good price on it from B&H photo. It's on backorder but I can wait . This one is still flying like brand new.
