Thanks for the video Don! As it is only a four motor drone, I would assume it still has some limited ability for control if one engine is lost?

If the quads I fly are any indication if one goes out, Newton wins and down it comes. With hex and octos they can lose up to 3 and still land safely depending on other factors, with a quad the odds are not so good.
