I do it like Minnflyer said but I use the plastic piece off of a torque rod type aileron setup instead of the coke can deal. I reckon ya'll know what I'm talking about. The plastic piece that is threaded down on the torque rod that the clevis hooks to. Just cut a small slot in the bottom of the rudder and then drop one drop of ZAP in there and push inn the flat part of the plastic piece. That leaves you with a hole to run the wire through............John
