It’s 2016 and we like our technology really small. Our phones fit in our pockets, our remotes are lighter than ever, and even our cars seem to be shrinking. So your new drone shouldn’t be an exception. This Axis VIDIUS Drone is 21% off right now and it’s so little, your biggest problem won’t be […]
