Theo,

I am still slowly progressing with my hardware build. I will probably start off with Mach3 and Profili2 to get a feel for the CNC process. I would love to try the GMFC combination later on, as it's airfoil stacking capabilities are something I would like to use.

As it will be a while yet before I tackle GMFC (given the additional engineering required), would love to see any new info you obtain.
If you get an update on your attached file, please post.

Rick
