Robert,

Have you looked at Sam Hoskins' splitter setup? Worth considering before investing the work and weight in the bellcrank version...

7. It's a very good thing to have a splitter in the rudder cables. That way, if the tail spring should break, you still have the rudder. Ditto the differential brakes. 

8. I think the aftermarket intermediate rudder cable bellcrank is unnecessary.
