Infinity MR is awesome. CP is awesome, but not ready for prime time yet - hopefully this revolutionary new horizon fw will be good.
NX1 is awesome. It's their first big foray at the big boy table though, so it has a few quirks. HDMI works but has some quirks. You'll need a lens that doesn't allow auto-focus. Also, for photos you'll need to buy the gentled.
My advice, buy Infinity MR with encoders, and AM. Sony's latest has the best cam for aerials now, but it's pricey. NX1 is awesome, but has some weird quirks.
Also not a fan of your Tarot, way too many things that can go wrong with that thing. If you do fly it, be anal about regular upkeep - make sure everything is properly fastened at all times. I'm madly in love with my new S1000. That thing exceeded all expectations and flies like a dream.
Best,
