I just received my Q500 4K today. As I was afraid would be the case, my Asus Memo Pad is NOT compatible with the CGO3 app. I really want to use the SteadyGrip! That was a big selling point for me in choosing this quadcopter. I would very much appreciate advice on which ipad or other tablet to buy to use with the SteadyGrip. I'd prefer not to spend several hundred dollars, but it's worth it to me to spend enough to get very good compatibility and performance. Thanks in advance for your help!
