thanks guys. I had figured that the distances from the cable ends as Walt described was probably the case. I've heard that it is ok to have "pushing" cable go a bit slack when you deflect the rudder, but wonder about flutter in such a case. Granted, the sig pig isn't a full-on aerobatic or extremely fast plane, but I do like to throw them around the sky a bit .
What's the advantages of a pull-pull system over a good, stiff pushrod?
