Good and thorough review, thanks BillM of this robust drone. This is my first GPS 'heavyweight' drone and for the price (circa $150), I am becoming more and more impressed the more I use it. It is easy to fly and stable and takes reasonable photos and videos, for only a 2K camera. I've slung a 4K camera under mine to get stabilised quality video, which works well but, of course, reduces flight times. As you demonstrate, its return home and low battery return work well.
The 4 hour battery recharge is a bit of a nuisance, but as I only have one battery (so far) I don't want to reduce its life through abusing it.
The only other negative point I have is that the compass and GPS calibration can be a bit fiddly. I have to make sure I have no 'phone nor keys in my pockets, to improve my first time synchronisation sucess rate. This might in part be due to the UK's northern latitude which is why, I presume, some drones are including GLONASS.
