My 4Star60 uses a length of fuel line fixed to the tail wheel "stanchion" and then "machine screwed" to the underside of the rudder. My 1st attempt put the screws too far away from the stanchion resulting in a very sloppy TW - looked like a drunk sailor on the deck of an aircraft carrier (at least that's what an ex-carrier club member called it). I moved the machine screws nearer the stanchion and control was greatly improved.
