Sorry for the delay in getting back to you. It's a great question!
To calculate the stability, you have to add up the moments of inertia for all the parts (adjusted for their position within the overall structure, using the parallel axis theorem). You want the largest moment of inertia to be at least 1.2 times the other two.
Our notes on the subject are available on the wiki here, and we have blog posts about it here and here. The blog posts include some fun videos from our early simulations, so please check them out!
Doing all the moment of inertia calculations by hand can be a real chore, but you can use High Frontier to do them for you... if you click the little "i" button next to the stability number in the Analysis palette, it will show you the actual numbers.
