Paul and others, If I were considering adding to the fuel capacity of the KR for range, I would add it BEHIND the main spar, possibly under the seat, or behind the passenger side, if I am solo, in order to have my worst case CG while I am heaviest and most stable, and as I burned fuel and got lighter, the CG would move forward. Take a quick look at the Cessna and Piper CG charts and you will see how they design them so that as fuel burns, the CG moves forward, so that their stability stay roughly the same throughout the flight.
