4.5 lbs is a lot of weight to add to foam horns. Even with CF on the ends. Joe, what did you do to beef up the horn areas?

Connection between the elevator bell crank and the balance counter weight bell crank is by a push rod and rod ends. All linkage and counter weight are in the fuselage. This push rod is also part of the elevator linkage to the stick. Elevator and aileron linkage is all pushrods.
