The controller never worked, they should sell defective controllers through this listing on Amazon. Got my controller from stock Revain 100. Guaranteed to get the controller, it was rubbish, flying it all was a waste of $300 and a 2 week waste of time. Seriously save your money and just buy one from DJI OR B&H, they will refund you if you don't I'm still reading this, don't do it. You'll thank me for the unwritten future of disappointment
