I don't think Aviation Products has a web site. At least I couldn't find it. There info is
Aviation Products Inc. (114 Bryant St. Ojai, CA 93023) 805-646-6042. They have several models available. You will want the lightest model which is a 4 inch wheel on a single fork. You will have to determine if you want a unit to fit a flat tail spring or a rod and what the mount angle will be. The unit I have is steerable through 30 degrees and then goes full swivel. I personally think it is the best unit available on the market for the KR. I use springs on my tail wheel hookup but I think Langford goes with cables only. It will work either way. I recall seeing photos of their available models with the spec's somewhere but I can't find them on the net. As for toe-in, toe-out, I don't think the Diehl gear has much flex fore and aft so I'd recommend going zero toe-in, toe-out. Even with my 30 inch legs I have the wheels set at zero and it handles on the ground, takeoff and landing, as well as any tricycle gear. I get zero uneven wear on the tires. I think it is the ideal setup. On the interconnect, the rudder cables should be either spring loaded at the peddles or a closed loop system. I went with the springs and it works well. You will want your tail wheel cable to be just a weeeeee bit slack so they allow the rudder cables to always be tight. With this setup, any rudder input you need on takeoff / landing is applied equally to the tail wheel and the rudder. With the wheel on the ground, it will be the controlling factor. When it lifts off the ground, or before it settles on landing, you already have the correct input you need. I can tell very little difference in the peddle movement needed for correction whether it is the tail wheel controlling or the rudder. I'm not sure you could properly simulate in on X-Plane or other simulators as it will vary by the exact physical setup on each KR, ie. rudder size, tail wheel cable slack, fuselage length (rudder power), etc. Builders can save themselves a lot of time by not trying to re-invent the wheel (no pun intended) and copy one of the many proven designs like mine, Langford's, Dan Heath's, or others. I don't have any close up photos. In the photo at http://mysite.verizon.net/flesner/lf103.jpg you can see it is a very standard installation. As always, your results may vary. Larry Flesner
