| Compared to the N9, the vertical and horizontal CG is almost exactly the same. Solidworks has the ability to calculate CG based on assigned mass properties of each individual part/component.
I would highly suggest purchasing a copy or at least doing your CAD work over a friends house who has Solidworks. It takes much of the trial and error testing out of creating a prototype.

I was not aware that solidworks could provide that info, and while the CG may be almost the same, with the electric conversion I was looking for an improvement. I guess after flying my Eagle 3 I got spoiled on how smooth that rolls with no mixing required what so ever.
If you take a look at the pics, I was able to keep the fore/aft CG the same while moving it closer to the rotor head to make rolls more fluid. The markings for the frames are where they will be cut out and the batteries will mount to the inside of the opposing frame to bring the left/right CG as close to center as possible.
  
I know that these look very crude at the moment, but this is just a prototype and entirely hand cut.

It looks like I'm going to have to go with a single frame set-up, so I ordered some sheets of G10 from McMaster-Carr yesterday. The good news is that I had the length wise CG dead on, and I think I've got a way to bring the span wise CG much closer to center.
