The unique wedge-shaped frontal area and large road wheels have been accurately reproduced from extensive research. Distinctive turret shape of the 1937 model has been faithfully rendered. Mechanically complicated suspension is detailed and easy to assemble. Assembly type tracks feature one-piece straight sections. Photo-etched parts for engine cover and radiator included. Clear parts for headlight lenses and vision block as well as metal tow chain are included. Officer and commander figures included. Comes with 3 marking options.

4. Operating and Display

Once assembled and painted, your Tamiya BT-7 model is ready for display. This is a static display model and is not designed for active play or rough handling.

• Handling: Always handle the model with care, preferably by its base or sturdy sections, to avoid damaging delicate parts like antennas, machine guns, or figures.
• Placement: Display your model on a stable, flat surface away from direct sunlight, extreme temperatures, and high humidity. These conditions can cause paint fading, warping, or decal degradation over time.
• Dioramas: Consider integrating your model into a diorama to enhance its visual appeal and historical context.

5. Maintenance

Proper maintenance will ensure the longevity and pristine condition of your model.

• Dusting: Regularly dust the model using a soft, dry brush (such as a makeup brush or soft paintbrush) or a can of compressed air. Avoid wiping with cloths, as this can scratch the paint or dislodge small parts.
• Cleaning: For stubborn dust or grime, lightly dampen a cotton swab with water (or a very mild, non-abrasive cleaner if necessary, testing on an inconspicuous area first) and gently dab the affected area. Avoid harsh chemicals or solvents.
• Storage: If storing the model, place it in a sealed container or display case to protect it from dust and environmental factors.

6. Troubleshooting

Here are some common issues encountered during model building and their solutions:

• Parts Not Fitting:
  • Ensure all sprue gates are completely removed and no flash remains.
  • Check the instruction manual for correct part orientation and numbering.
  • Lightly sand or trim mating surfaces if there's a slight misalignment.
• Decal Silvering:
  • This occurs when air is trapped under the decal, making it look silvery. Apply decals to a glossy surface.
  • Use decal setting solutions (e.g., Micro Sol, Mr. Mark Setter) to help the decal conform to the surface and eliminate air bubbles.
• Paint Issues (e.g., brush strokes, uneven finish):
  • Ensure paint is properly thinned.
  • Apply multiple thin coats instead of one thick coat.
  • Allow sufficient drying time between coats.
• Photo-Etched Parts Detaching:
  • Use super glue (cyanoacrylate adhesive) for photo-etched parts, as plastic cement will not bond them.
  • Apply a very small amount of glue to avoid excess.
