With all due respect to Mr. Tharpe, that 1/16" issue wire isn't going to last very long unless every landing is a perfect one.

I just finished my third Four Star, for my grandson. I had to replace the kit tail wheel wires on both of the previous ones. One lasted a full flying season before breaking; the other got mangled in a ground incident, and broke when I tried to straighten it.

On this new one, I just fitted a DuBro unit to save myself the trouble later. This particular installation is easy, and can be completely replaced, if it ever becomes necessary, in five minutes.
