Honestly, that covers my entire use case, today. I purchased a drone last year with the desire to toss open-source auto-pilot firmware on it, but I've always operated it within line-of-sight... at least, I've always intended to operate it within line-of-sight[0]. :P
[0] I failed to properly calibrate the drone on its third flight, where it took of at full power, up and to the left. It continued to try to "correct itself", which resulted it in flying in an arc, landing upside down on the roof of a house 5 doors down. It's not fun introducing yourself to the neighbors by asking if you can use the ladder you carried down the block to retrieve the drone that nearly lodged itself in their chimney. Or maybe it is ... in my case, he was a drone hobbyist with similar piloting skills as myself, so he was very understanding and ended up giving me a battery he had that he found out wasn't compatible with his.
