Like the title I don't usually write anything but I have to about it. I usually buy the cheap ones to get by and I've gotten some really good ones for a little less than this instruction. Well, they pull out the battery. Good luck, it's like it's blown and ok, one flight and you're done - because I can't charge it I hope others don't have this problem, I'd love to use it more but it's done, I move on to the next.
