I've got too much on my plate to check right now, and it's been a
looooong time since we did that, but the basic premise of the new
airfoil is that it was a direct "swap-in" for the RAF48, with regards to
lift coefficient, moment, etc, and I believe that includes the CG range
(modified to remove the aft two inches). The answer is probably shown
in the data at http://www.krnet.org/as504x/ or in the links at the
bottom of that page. I do know that Troy Petteway swapped it in for the
RAF48 with no issue at all, and I'm sure he's not the only
one.....that's essentially what we've all done. Wherever the templates
show the spars, that's where the the templates are mounted.
