Here is a prectical approach for trailer construction. The guys I fly with dreamed this up. The Dawn Patrol Guys pull there airplanes all over the US for hundreds of miles one way. The have much more complicated planes to assemble and disassemble than the KR. They have been doing it for years. You can be build one if you think of ways to adapt it to KR's. It would be easy to modify their trailers. Go to http://www.kcdawnpatrol.org/trailers.htm.
