Hi Craig:

Point I was trying to make was that if one is going to use the leading edge for C.G. on a swept wing, you have to balance preferably directly at the leading edge which can be mechanically difficult. As you move your finger aft of the apex of the leading edge, I think you can see in the photo that to maintain the same C.G. line, you have to move to a different location on the leading edge since the planform is not a rectangle, but 1/2 of a parallelogram.

Tom Cook's Firebird C.G. locater does a good job of placing the balance point right at the apex of the leading edge.

All of this is probably superfluous anyway since it seems that guys are flying anywhere from 12 1/2 out to 14 1/8 with good results as I have seen your excellent flights as well as David, Vern, and Phil's flights.

I usually go out and fly and see if it wants to tuck or snap and adjust the final C.G. accordingly like no doubt you do as well.
