I am not exactly sure, but I can tell you that from firewall to the axle of the tailwheel is 136.125. You can take 4 to 6 inches off that to get back to the rudder post. If I remember, I will measure the difference for you tomorrow, if you need an exact number. Remember, this is a stock KR2.
The W & B spread sheet that is available on our site will tell you almost anything you want to know about W & B. The datum on that sheet is the Firewall. Why would you use anything else, as it would be most difficult to change it's location. See N64KR at http://KRBuilder.org - Then click on the pics See you in Mt. Vernon - 2006 - KR Gathering There is a time for building and a time for FLYING and the time for building is OVER. Daniel R. Heath - Lexington, SC -------Original Message------- If you have it available, could you each (these are all modified aircraft I think) post the distance from firewall to rudder post.
