This is the final version of my sphere
I have made too many spheres and interchange parts among other sphere.
Hovering is very stable but not forward flight.I might have to reduce the bottom vanes surface area or reduce the deflection of the vanes to reduce drag.
The total weight is 976 grams, cg is about 0.25 inches below the meridian.
Again, i am using the same three Rate gyros as mentioned in earlier post for stability.
