Here is what it looks like installed. The picture is self explanatory.

Missing from the pic is the smaller plastic cylinder which goes on the rudder itself holding the wire.

After everything is in place, deflect the rudder fully and cut any wire beyond 1/3" or so past the small cylinder.

I buy these things by the dozen as I've used them on planes from .40's up through my Giant Scale U-Can-Do.

One other benefit of this tail gear; the plane sits more level. This causes it to yaw less at run up.
