I want to clarify what I was saying in my original post about reversed aileron differential when inverted.
If you have a plane with an amount of differential setup that at full right aileron deflection the left aileron deflects down 20 degrees and the right aileron deflects up 30 degrees. As the plane rolls inverted that right aileron is now down 30 degrees and the left is up only 20. Now viewing this plane from sky view the differential is reversed from what it was. The down aileron now has the greater throw.
I hope this clears up what i was trying to say.
