I'm running Easy VFR on a Galaxy Tab PRO 8.4. I use it strapped to my leg with a MyClip Mini strap. This combination works quite well and the screen is still visible outside even in sunny weather. I returned an LG Gpad 8.3 because as soon as I got outside I couldn't see anything on the screen.
A newer version called the Galaxy Tab S with an oled screen might be even better but I haven't seen it yet.
