I've been test flying it, indoors, trying to get the feel of it, and had it survive a couple of minor collisions. I tried it, for the first time, outdoors this morning, in the middle of a farm field, but quite briefly, and at just a few feet off the ground. I tested the return to home button, and was quite surprised/worried that it shot up to a height, and lingered there, before eventually coming back down, landing precisely where it had taken off from. It took me a while, to work out that this was probably normal behaviour for the home button - It would need to rise to an altitude, to clear any potential obstructions, before making any horizontal moves, then finally coming vertically down over it's takeoff location. Is that how the behave?
