Build the Hasegawa 1/72 G4M1 Betty with a focused order of work: cockpit and figure first, then seams, canopy masking, and a restrained Rabaul paint scheme.
Quick answer
Build the Hasegawa 1/72 G4M1 Betty in this order: assemble and paint the cockpit and included figure first, close the fuselage and clean seams, mask and attach the canopy, then paint the airframe before final assembly. This sequence keeps the figure accessible and prevents paint from bridging seams you still need to sand.
Why the figure changes your build order
The Rabaul front line inspection boxing includes a figure, which turns a straightforward aircraft build into a small diorama decision. If you plan to use the figure, paint and place it before closing the fuselage or attaching the canopy, because reaching into a finished cockpit risks knocking off small parts and smearing paint. If you prefer a clean aircraft-only display, set the figure aside and build the cockpit as you normally would.
This is also the main trade-off of the kit: the figure adds display value but demands earlier planning. Decide its role before you start assembly rather than after the fuselage is closed.
Canopy masking and seam work on a bomber airframe
The G4M1’s large greenhouse canopy is the most visible part of the model, so masking deserves its own pass. Use thin strips of tape to follow frame lines, then fill the panels with wider tape or masking fluid. A common mistake is pressing tape over detail without burnishing the edges, which lets paint creep under and leaves ragged frames.
Fuselage seams on a bomber are long and flat, which makes them easy to spot under a glossy finish. Sand progressively and check with a primer coat before painting the final scheme; skipping that check often reveals a seam only after the camouflage is on.
A restrained approach to the Rabaul scheme
Rabaul-based bombers are often modeled with heavy weathering, but the kit supplies no specific paint callouts or decal options in the catalog facts. Treat the scheme as a research step: choose a reference photo or profile you trust and match your paints to it rather than guessing from the box art. Keep the base colors thin and build them in layers so panel detail stays visible.
If you are new to Japanese bomber colors, a simpler two-tone finish with light chipping looks more convincing than a heavily weathered aircraft with inconsistent references. The figure gives you a scale reference for how much contrast to add.
Step-by-step build sequence
- Prepare and paint the cockpit and figure: Assemble the cockpit parts and the included figure, then paint them before closing the fuselage. Check that the figure fits through the cockpit opening or can be added later without forcing it. Test-fit the figure before painting; if it will not pass through the opening, leave it out until after the fuselage is closed.
- Close the fuselage and clean seams: Glue the fuselage halves, then sand the center seam and any joint lines with progressively finer grit. Apply a thin primer coat and inspect under a light before moving on. A primer check now prevents a seam from appearing after the camouflage is finished.
- Mask and attach the canopy: Mask the canopy frames with thin tape strips, burnish the edges, and fill the panels. Attach the canopy after the cockpit is complete and before final airframe painting. Burnish every frame edge; paint creep under tape is the most common canopy mistake.
- Paint the airframe in thin layers: Choose a reference for the Rabaul scheme, then build the base colors in thin coats rather than one heavy pass. Keep the figure nearby as a scale and contrast reference. If you cannot find a reliable reference, a clean two-tone finish is safer than invented heavy weathering.
- Final assembly and figure placement: Attach the remaining parts, remove masking, and place the figure last so you do not handle it during airframe painting. Check that the figure sits naturally on the display base or aircraft. Leave the figure until the end to avoid paint rub and accidental damage.
