Thanks for posting about the TV. I thought it sounded perfect for my needs so I went to CVS and they had three of them there. I bought one and so far I'm very happy with it. It's quite an update from my 8" DVD player screen and I found it plenty bright, at least in the long dark box I put it into. No angle issues in the box either.
I ran it and two RX plus Oricale on a 3 cell 4800 mah lipo no problem.
Here is a video of me out in the field with it.
