They function as designed with easy install. A good bit pricy.

Spring material very soft. One spring has stretched after 2 flights. Tailwheel has swivel pin release, so that is how much pressure it experienced.

I had one of the small Tailwheel spring clips pull open on my Extra 300. This is the prefect replacement system with the oval clips with safety cotter pins.
Works great to stop the shimmy on the Scott 3200 tailwheel on my CUB
Could have been suppied with slightly longer pieces of chain, too short for my aircraft.
Was wanting to put these on a Taylorcraft with a maule tail wheel. The distance between the tail wheel an the rudder arm was to short.
