You can do it in one piece with a bow cutter(S), but you need to build a jigg rail for the outter tip part of the wing and a set of extended false ribs. You cut the wing first then go back and do the tip area seperately. I am using these style of wings on the design I started back in 2009 (not finished yet, fuse is built up). I also plan to use these on my Black Magic VF3 E.

You can cut these in two sections also, but be very careful to get the halves matched up in the shucks, taped and glued with Gorilla glue and weighted well. Don't forget to line the shucks inside with wax paper. David Snow has a wooden set you can order based off the wings from the Spark (blog on them).


Good Luck!
