I picked up a used 3DR Hexa from a guy on RC groups for flying a Go-Pro around. So far it has done exactly what I wanted. These mutirotors are one of (at least for me) the easiest things to fly. I have been flying RC planes for 20 years and helis for 5 and these are so much easier.
Anyways now that I feel comfortable with the platform for AV I now feel that I want something bigger, and more stable for flying a larger camera. At first I was thinking of a Y6, I like the wide open front, but I don't like the loss of effeicency, nor the low hanging props and I think I also want 8 motors for redundancy. Thus the Octo-V seems like it would be the answer.
I want about 1.5 to 2 meters accross the front (I did say large). I will custom build the frame, to my specs, plan is for square alluminum tubing 20 to 25 mm. 6 cell Lipo 10 to 20 AH, and 14" props. 3 Axis gimbal, FPV for camera operator, and telemetry.
My one question, at the moment is, what angles do the V need to be? I searched the wiki and found nothing.
So far I have bought a 2.5 APM with telemetry, and ordered 1 motor, ESC and prop from RC timer to see the quality and measure power to make sure it will do what I need, If I am happy I will order enough for the rest of it, plus spares.
So what angle do I set the V to and is there anything else I am missing?

You can build the angles at whatever you like, you'll just need to manually adjust the values to match whatever motor configuration you use.
Each arm of the "V" is 14 degrees offset from the center line. Your plan sounds a lot like a build I have been working on recently, an octo-v with 15" props and 6 call batteries. I'm in the process of designing a 3 axis gimbal system, but currently am using a 2 axis as my designs develop. you may be interested in the work I have done so far:
