I acquired a P2/H2-3D several weeks ago and have been flying it non-stop as weather allows. I'm running mini iOSD, 200 mW Boscam TS351 Tx, Boscam RX-LCD5802 5.8GHz LCD Diversity Receiver 7 Inch Monitor, Fat Shark Spironet Omnis, a Patch antenna on Ch2, GoPro 3+ and having great luck. I would probably jump to a higher output Tx next, as I'm only sitting at approx 700 Meters before I get snow. I may just need a Fat Shark Panel antenna to fix that up though. I bought the FPV hub, but still elected to solder, since I'm not using the DJI Tx setup thats just plug and play. It was alot cleaner install that way.
I elected to try a set of "Video Goggles" which are still on order, rather than Skyzone goggles (cant use Fatsharks for this setup), with the idea that I can plug them in to my monitor. They were really cheap, so I hope they work well. I chose the Boscam monitor just simply because it is rated to be much brighter, and I'm really glad I did, because even IT at times can be difficult to see when its bright outside.
As an update to my previous post, I was able to hit 1 Kilometer last night, so alot of my interference must be where I've been flying. I didn't try to exceed it yet. I may have more range than I realize when I get a fairly clean environment.
