The purpose is you always want to be facing the drone for signal....have you been sleeping in class again? And again, if you know what way your facing and you can see in relationship to that what way the drone is flying, then it is quite easy to determine if the drone is left/right - behind/front of you. Not sure what your not getting...I'm moving you to front row seats of class.So when I'm flying I need to be spinning around then??
Correct me if I'm wrong please, but it seems the only useful feature is that I can turn the drone , which will spin the world around it, till its pointing at me then I could fly straight back in case I lost my VLOS. Where as with the other one I would know where in the sky to look...
Have you flown yet using it?...I think your gonna be one of those "gotta see it in action" to comprehend kinda guys
