Hello,
This is my first post here, and it actually is a cry for help.
I don't have much experience assembling copters. I am a pro photographer using often small DJI phantom 2 with gopro.  Unfortunately photo quality of gopro leaves a lot to be deserved, so I decided for a bigger copter. I bought aerosky C17.

It was over 1/2 year ago, when I was preparing to move out of Canada, relocating to a small Caribbean island - Dominica.  When still in Canada, I saw somewhere online info how to add OSD, large gimbal, and make a full FPV system based on C17 and using Sony NEX camera which is capable of interval shooting.

Just before moving I ordered from ebay several components which were described online as needed.
a mini OSD board, HDMI to USB converting box, gimbal DYS BLG3SN with board, a power converting board, transmitter and small video monitor/receiver.

Now I have serious problem. I unpacked stuff from my container after relocating, but have no idea where I have that info how to create FPV system.  I have components, but I can't find any tips how to put it together! 

As said I don't have much experience in making my own systems. I can assembly something when I have some sort of guidance. But now I can't find it anywhere! I have this stuff sitting on my table, but I am not sure how to proceed.

does anyone have knowledge how to assembly FPV system using this gimbal and NEX camera?
Any tips would be most appreciated.  It would be super hard to order different components from dominica. Post is very slow here. So I hope I can do something with stuff I already got.

Many thanks for your help and time. Cheers
Derek
