Well I just got my (used) insignia flex elite tablet and as this has already been brought up before with people looking for cheap tablets to use with their phantom I thought I'd share my 2 cents. I got this on eBay, for $70, slightly used. It's a 7.85" screen, ips display 2048x1536, quad core rockchipc3288 , 2gb ram, 16gb rom, GPS enabled. For me the smallish size just feels right and this screen is absolutely amazing. Very very bright. Good colors. In fact even without using a matte screen cover I could use this for fpv in very bright sunlight. The tablet is quick, responsive and I've had no lag in terms of go app /litchi operation or video lag. One significant drawback is that the tablet does not read well all SD cards. In fact it only reads fat 32 formatted cards, hence no 64gb cards. One other important notice: when using go app the tablet failed to keep up with saving the live video feed (my LG g3 had never had any problem with it) . In fact I lost video feed during a flight and that did not resume even upon landing. With litchi I did not notice any such problem. I'm guessing the tablet is unable to both process and save the live video feed. As litchi does not save video previews that problem did not recur with it. All in all an excellent, cheap solution for good fpv screen as long as you disable saving video previews on the dji app or use litchi.
