This one is a bit quite a challenging kit to work on and first time merging with the old MG 1/100 Zaku parts. Lots of drilling works need to be done, also require different size of the poly parts ready if you plan to fits in with HG1/144. As you can see, it’s not really perfect hand works so I fill some putty to repair, at the same time make it look better. I’m not using 2 hour fast dry putty since I still got half of the Tamiya 10 hours putty around. Better off not wasting, it just the problem needed to wait longer to dry. The rest of the kit sanding is nearly 100% complete so next month I can start coloring. The photo here shows how it going to looks like in the final stage. Although I did have problem solving the energy pipes linking to the backpack and to the booster legs. Somehow I manage to find useless electrical wire to do the jobs. Not quite liking it much but it does solved my problem.
