RE: THE OMP KATANA ARF's HERE!!!!
Well I don't have one of these planes...but what about this..
Before the wing is attached.
Drill a hole into the front, in the middle of the wing...then slit the fuse right at the leading edge of the wing. Peel the covering back first. It would look like the servo wire disappears into the fuse about 1/4 inch in front of the wing. Use a piece of straw slit to protect the servo wire if need be from glue during the wing. I guess there are probably many more ways....but seeing as how these are the initial prototype versions.
