Robert, I should also mention that Pazmany wrote a great book on gear design, but you probably don't need to know all about airliner gear to do this job on a KR. One excerpt from his homebuilding book (not the gear book) is at http://home.hiwaay.net/~langford/misc.html about midway down, but another good one is at http://home.hiwaay.net/~langford/gear_location.pdf ...
