After working on them both in Canada I came back to Japan when my XN Unit arrived shortly thereafter. After assembling the unit by itself (which gave me a surprising amount of difficulty! Backwards parts and I swear the instruction manual is actually incorrect in one section and can be a bit confusing at times.) I tried combining it with the O Gundam. It can fit into the slot on the back of the waist armour and in the slot where the GN Drive connects. I elected to leave the GN Drive in place and set it in the back skirt. I changed the configuration a bit and I finally got the XN Unit into a position that I was satisfied with. I intend on paint the XN Unit in the same colours as the O Gundam (modified roll out) and making it the "Super XN-O Gundam" paying homage to the "Super MK2 Gundam" I mentioned in the previous post. Take a look at some of my pics.
Yeah I know what I said about "No Flash" but I'm leaving those flash pics in just so you can see the details a bit clearer and to blot out the background nonsense (although I wouldn't call Milla Jovovich in her underwear nonsense)
