Hi all , i have just got a H501 a , I have done a couple of short flights without issue . yesterday however after a flight and some photos i used the return to home and it landed ok but the rotors would not stop , the altitude was showing 7 meters ? ? .
any ideas what the issue could be , as i had to remove the battery while the blades were spinning , or is there a control on the app to shut it off ?
Im using an iphone 7 ..

please lock the rotors by pulling the left virtual stick on APP to the nether left corner and right virtual stick to the nether right corner.

thank you..

Or.. Pull down virtual throttel and wait for second
