Just so everyone, especially the new builders, don't get the idea that you HAVE to have a full swivel breakaway tailwheel, I never regretted having a direct steer on my first KR. I felt like I could turn it on a dime. Maybe it did not literally turn over one spot, but it felt like it did. I could make it go anywhere I wanted, when I wanted. When I stepped on the rudder, it responded and when I needed to correct for overturn, it corrected immediately.
I like the idea of a breakaway, if you can afford it, because it eliminates the problem of still having rudder in, when the tailwheel touches down, maybe going the wrong way. But, I never experienced this problem because I had to keep the tail up as long as it would stay up. I believe that the best tailwheel for the weight, that you can get and are willing to pay for, is what you should get. Just keep everything in perspective. There is a time for building and a time for FLYING and the time for building has expired. See N64KR at http://KR-Builder.org - Then click on the pics Daniel R. Heath - Columbia, SC See you in Mt.
