HG 1/144 HOBBY HI-ZACK (A.O.Z RE-BOOT Ver.) Build Tips

Quick Answer

To build the HG 1/144 HOBBY HI-ZACK (A.O.Z RE-BOOT Ver.) cleanly, focus on careful nub removal on its dark-colored parts, pre-fit the backpack sub-assemblies, and use a gloss coat before applying the included decals.

Step-by-Step Build Guide

1. 1. Prepare the Dark Plastic Parts: Cut each piece 1-2 mm from the gate, then use a glass file or 1000-grit sanding sponge to sand the nub flat. For dark blue and gray parts, follow with a 1200-grit sponge to remove any whitish stress marks. Common mistake: using a hobby knife to shave nubs on dark plastic often leaves a visible gouge. Stick to sanding for a smooth surface.
2. 2. Assemble the Backpack Sub-Assemblies First: Dry-fit the backpack's booster and thruster parts before gluing or snapping them together. The asymmetrical design has tight pegs; if they feel too tight, gently sand the peg with 800-grit sandpaper to avoid cracking the socket.
3. 3. Clean Seam Lines on the Arms and Legs: The arms and legs have visible seam lines on the outer halves. Apply a thin layer of plastic cement (like Tamiya Extra Thin) along the seam, press the halves together, and let it dry. Then sand the seam with 1000-grit paper until it disappears. Checkpoint: after sanding, wipe the part with a damp cloth to remove dust before painting or topcoating.
4. 4. Apply a Gloss Coat Before Decals: Spray a thin layer of gloss clear coat (e.g., Mr. Hobby Gloss) over the entire kit. This gives the decals a smooth surface to adhere to and prevents silvering. Wait 30 minutes for it to dry completely. Common mistake: applying decals directly on bare plastic can trap air bubbles. A gloss coat eliminates this issue.
5. 5. Place the Decals and Finish with a Topcoat: Use tweezers to place the included decals on the gloss-coated surfaces. Press them gently with a cotton swab to remove any air bubbles. Once dry, spray a matte or semi-gloss topcoat to seal everything and match the rest of the kit's finish. If you prefer a glossier look, skip the final matte coat and leave the gloss coat as the finish.
