I believe Sig uses half of the original dihedral, which still leaves quite a bit. To me the point of building old kits is for the different look and different flying qualities. The Hogs I've seen with more dihedral taken out really don't look like Hogs anymore, and so the way I see it, what's the point? I think Sig got a nice compromise that still looks really good. I would just go with that.

Compared to a Kaos, the Astro Hog is a much earlier design, and my inclination is to treat it as such rather than try too hard to make it into something it wasn't. If I want a Kaos I'll build a Kaos. But it's a hobby; I'm only giving you my own point of view. Enjoy whatever you decide!
