Hello all. I am a novice builder working on my cap-x. I purchased the Du-Bro HD pull-pull system for the rudder as suggested by Chip. Now I am trying to figure out what additional connectors/hardware are needed to attach to the horns on the rudder and the servo arm. Can anyone direct me to a Du-bro or other part that are required to complete the connection. I thought that these parts would have been included in the pull-pull system. Thanks.
