I checked my "Tony Bingelis" books, before we lost power and lights in storm that rolled through, and he says the rule of thumb is as follows: Plane in level flying attitude, find the point (on the top longeron in our case) for the C.of G. From that point drop a line to the floor at an angle in the range of 15 to 20 degrees forward. That would / should be the contact point of the tire to the ground for the main gear on a conventional geared aircraft. I think ( going from memory here) that my axle is pretty much in line with the lead edge of my wing. With an airplane as light as a KR, where the pilot is such a high percentage of the gross weight, you will probably have to settle for light tail weight with no one on board. Whenever I carry a passenger, I always make sure I can get the tail up well before lift off to insure I have a flyable airplane. Remember, my opinion is worth what you pay for it. :-) Larry Flesner
