Yep, a 128 gb micro SD card works great, but I only use it when I'm on the road. Close to home, I still use my 3 16 gb cards. I video in 4k so I use a little over half of a card per flight, and because of that, I think the sweet spot for me would be to get a 32 gb card so I can do at least a couple of flight and maybe a third.
