The X-101 can haul around heavy action cams, so yes you can outfit it for real FPV if you'd like.
Try the "FPV Kit" that's for the Syma X5. It has it's own battery inside the camera with a built in 5.8 GHz 200mW transmitter.
The camera lens angle can be adjusted, which is nice, and comes with a 4.3" monitor that has a built in receiver and a Planar antenna too.
The camera will also record on it's built in SD card, but the plug and wiring don't jive with the X-101, so you can't control that from the radio,
but there are youtube videos on how to wire a small switch for recording control before flight (like you hafta do with a lot of cameras anyway).
The camera is extremely light weight, streamlined (unlike a board camera set up) and the quad won't even know it's there!
This is what I used on my X-101 and it worked like a charm, plus it's only about $50 bucks for everything you need.
