Brian, I assume you're planning on using the thicker 18% AS 5048 airfoil tapering to the 15% AS5046. Otherwise, if you are simply swapping to the 16% AS5046, you don't need to change the main spar at all, or replace the outer spars. Just didn't want anybody to get the impression that changing to the new airfoil required hacking the main spar out. More info on the airfoil is at http://www.krnet.org/as504x/ , with installation instructions at http://www.krnet.org/as504x/ . The thicker airfoil gives you more room for fuel in the wing tanks, and the potential for a main spar that is either lighter or stronger than the plans version (due to it's extra height), whichever you decide to use.
