? ? I would recommend the "Aviation Products" tailwheel assembly that has served me well for 550 hours now. I think Mark Langford used that same assembly on 56ML I modified it a while back by having the arm lengthened a bit over one inch and installed a Matco 6" fully pneumatic wheel assembly (not shown in the photo). I love it!! It totally eliminated all the rumble of the old 4" solid wheel. My KR handles on the ground as well as any tri-gear with no braking action required. The springs are Maule anti-shimmy springs. The unit is steerable with breakaway full swivel at about 30 degrees. I can spin the KR on one wheel on the ramp.

I have over 1100 hrs on mine now. I do recommend adding a flat washer type bushing to the bottom of the vertical shaft so you can use the top nut on the tailwheel to preload it to prevent shimmy. Other than adjusting the preload about every 50 hrs or so, and replacing the bearings once or twice in 20 years now, it has been about as good of a tailwheel as I have ever owned. <http://www.aircraftspruce.com/catalog/lgpages/homebuilder_tailwheel2.php> -Jeff Scott Los Alamos, NM
