Finally someone out there made it possible for my ipad pro V11.1.1 to connect with my bird's controller. Was a bit breezy and branches low... but manual TO and LDG was smoother'n a young girl's thigh. Off to a real field on the next calm day. With the Ipod's luminance turned way up there was never a problem seeing what was going on. I'm going to cancel my order for the Crystal Sky.
