Re: rudder attachment points
Hi Patrick,
Can't say what the rest of the world has done; however, I followed Poly Fiber's general advice of wrapping it around edges like this.
I am sure the plane will fly either way; but, having a wrap around/wrap in gives you greater strength with regard to fabric delamination; or, more likely, paint delamination (particularily with aerothane) starting at the edge.
Sincerely,

Thanks Dave, will wrap the egdes,!!!! Thanks again!
Re: rudder attachment points
I did not wrap the edges, just cut them off flush. There is such a large surface around the cutouts that the fabric and tapes are glued to that there is plenty of strength. Even on things like the round inspection access holes a flush cut is all that Polyfiber recommends.
