If you work the tail wheel off the rudder, you need to move the coller or install a second one below your tail wheel bracket. If not, you will transfer your landing shock directly to the rudder. I have had several tail wheels on my Kadets all woring directly off the rudder only this way without any problems. Heres a picture to explaine what i'm talking about. If you look closely you will see i used a piece of carbon rod that passes thru the fuse & stabilizer for added support .....Gene
