So, I take it that you want to have your elevator balanced. That is a good thing and can be done by two methods that I know of. One is to put an internal balance arm inside the fuselage, and the other is to put weights on the ends of the elevator. To do this, you normally use part of the horizontal stabilizer by making it part of the elevator and putting weight in the foremost portion of it until the elevator will balance on the hinge point. The other method is much like you balance the aileron by adding an arm with weight as far forward as possible.
I am confident that someone with pics of these methods will let you know where they are. And yes, it would be very nice for the KR to finally make it into the "open source" of aircraft plans, and for the wing and tail surfaces, Mark has already made that happen by presenting the design and templates of the new design. As far as testing goes, you will just have to be sure that your work is straight after you have it glassed in. Come to the Gathering this year and learn more in two days than you could in a year. See N64KR at http://KRBuilder.org - Then click on the pics See you at the 2009 - KR Gathering in Mt. Vernon, Ill There is a time for building and a time for FLYING and the time for Flying has begun.

The wisdom of many could result in a royalty free best of class.
