COBI Vickers A1E1 Independent Tank: Great War Build Tips

Quick answer

Build the COBI Vickers A1E1 Independent Tank by sorting bricks by color, assembling the five rotating turrets separately, and applying decals after the main body is complete.

Step-by-step build guide

1. Sort bricks by color and size: Open all bags and separate bricks into piles by color (olive green, dark green, gray, black, tan). This saves time later and prevents using the wrong piece in a turret. Common mistake: mixing the small gray hinge bricks with the larger ones, which can make turrets wobble.
2. Assemble the main hull first: Follow the manual to build the lower chassis and track sections. Press each track link firmly into place—loose tracks are a common issue. Check that the wheels spin freely before adding the upper hull. If a track link feels loose, reinforce it with a dab of clear adhesive (not included) for a permanent display.
3. Build each turret separately: Work on one turret at a time, starting with the largest center turret. Use the parts from a single bag group for each turret to avoid mix-ups. Ensure the rotation plate clicks fully into the hull before attaching turret walls. Common mistake: forcing the rotation plate into the wrong orientation, which prevents the turret from turning. Test the rotation after attaching the first wall layer—if it binds, disassemble and check alignment.
4. Apply decals after assembly: Place the decals on the finished model using tweezers for precision. Position the tank museum markings on the hull sides and turret numbers after the model is complete. Common mistake: applying decals over dust or fingerprints, causing bubbles. Clean the surface with a dry cloth first.
5. Display with a stable base: The finished tank is top-heavy due to the five turrets. Place it on a flat, level surface away from edges. For a dynamic display, rotate each turret to a different angle. Common mistake: storing the tank on a shelf where it can be bumped, causing turrets to fall off. Consider a clear acrylic case to protect the model from dust and accidental knocks.
