Althought it seems to me it's the first question that comes in mind when building a multirotor, there's not really much interest in determining which is the best design (deppending on the use) on the net.
I only could find some tri/quad comparation, but nothing comparing the CPU-balanced ones.
Could you please tell me the main (relative) differences between them (including their possible layouts like raddial/coaxial). Just smack here what you now :P

If you do more than hover around then Y's have a distinct disadvantage because of dis-symmetry of lift.

I am working on a wind-resistant copter with 15" props and 2/3 kgs payload.
I am leaning towards an Y-6 configuration with coaxial motors. It minimizes the surface area for susceptibility to gusts of wind and interference with the visual field of the 360cam. I hear that if the motors are not too close together on the Z-axis, coaxial motors can be quite efficient. @JSmith do you have any data showing how much less efficient this is?
I am also considering ducted fans although I am wondering how much that will affect the susceptibility to winds.
Well, this is kind of an old thread, but since none of the questions were never really answered, I don't think the admins will mind.
To answer your questions, I'd say that having more surface will affect positively the stability, so I guess radials are more stable. But dont really listen to me.
In the end, this toys are really unstable by nature, so what you really need is a good software to handle external fluctuations
Any difference in ability to remain stable in strong, uneven wind ?
But althought it's a wiki-like page, there's no extra info (at least when i click on them) about each.
