I had a moment of hair standing when under 15%, the drone is 3 feet in front of me and 5 feet high, and I left stick down to land. It would not land. The warning noise actually distracts me from looking at my phone or the controller, and I did not want to take my eyes off the drone because it had attempted to ascend for the RTH once. When I did look down, the phone was asking me to confirm that I want to cancel RTH. For about 30 seconds to 1 minutes, the drone was in grabbing distance, and I was so tempted to just grab it.
Make sure you know how to cancel RTH or enable it from the controller only. Know it like the back of your hand. Mock play scenarios. Don't rely on your phone because if you are in some sort of panic mode, you can only rely on your instincts.
There are two types of drone pilot. One the has crashed before, and one that will crash.
