Just finished my tail cone tonight and waiting for the rest of the kit to arrive but as I was looking how the rudder cables run cross the tail cone, I couldn?t help wonder how long will does plastic fittings (SB750-10) last special at the first bulkhead. There is a good amount of tensioned rubbing on those and they are not easily replaceable unless you slit them which is not much of a problem so I was wondering is there anything else that will protect these or they are just as it is.
