Archie, how do you balance the weight of the oil rolling inside of the
rotors? :)

Perhaps I did not clarify my last statement.
All our engines are piston.
I have only balanced one rotary. Since the amount of oil
contained in one rotor, would be the same as in the
adjacent one, I did nothing.
In piston engines,we add the weight of the oil in crank
throws to the bobweights. These vary in amounts
depending the length/diameter of the passages.
Paul Yaw seems to be on top of the rotary dynamics,
perhaps he may add to this.
