Overskyrc's microquad Super-X (http://www.overskyrc.com/superx-micro-brushless-quadcopter-p-507.html) FPV mod. Learning to fly FPV... with epic crash in the end. (Cover works great - no any damages after crash, so you can contact me in comments if you want *.stl to print your own)
I use Spektrum SPMVA1100 FPV cam (http://www.horizonhobby.com/ultra-micro-fpv-camera-and-video-transmitter-spmva1100) with custom 3D-printed antenna cover.
5 mins of flight with FPV with 1S 650 mAh noname bat.
