Learn how to assemble and finish the Model Set Boeing E-3A Sentry with practical steps, painting tips, and common mistakes to avoid.
Quick answer
Assemble the Model Set Boeing E-3A Sentry in logical sub-assemblies, paint before final assembly, and use careful masking for the radar dome to achieve a clean finish.
Why sub-assemblies matter
The Boeing E-3A Sentry features a large rotating radar dome that is its most distinctive element. Building the fuselage, wings, and radar dome as separate sub-assemblies lets you paint and detail each part without awkward handling.
This approach also reduces the risk of breaking delicate parts like the radar dome supports during final assembly.
Painting before final assembly
Painting the interior and exterior before joining major parts avoids hard-to-reach areas and overspray. The E-3A's radar dome is usually a darker gray compared to the airframe, so painting it separately makes masking simpler.
If you prefer a specific paint scheme, check the kit instructions for the recommended colors, but don't stress about exact matches—most military aircraft models look great with a few subtle variations.
Assembly and finishing steps
- Prepare the parts: Remove parts from the sprues using a sharp hobby knife or sprue cutter. Sand down any remaining nubs with fine-grit sandpaper or a sanding stick. Check that all parts fit dry before applying glue.
- Assemble the cockpit and interior: Glue the cockpit interior parts together, including the seats and instrument panels. Paint the interior before closing the fuselage halves. Don't forget to paint the interior before assembly—once the fuselage is closed, it's hard to reach.
- Join the fuselage halves: Apply plastic cement along the edges and press the halves together. Hold firmly for a few seconds and wipe away excess glue with a damp cloth. Use rubber bands or tape to keep the halves aligned while the glue sets.
- Build the wings and tail: Attach the wings and tail plane to the fuselage. Ensure they are aligned and level before the glue dries. Check alignment from both front and top views to avoid a crooked model.
- Assemble the radar dome: Glue the radar dome parts together, then attach them to the fuselage. Paint the dome separately for best results. Handle the dome gently—it's the most fragile part of the model.
- Apply primer and paint: Spray a light coat of primer to reveal any imperfections. Then apply the main airframe color, followed by the radar dome color, using masking tape for clean edges. Let each coat dry completely before applying the next to avoid runs.
- Add decals and final clear coat: Apply decals using warm water and a soft brush. After they dry, seal with a clear matte or satin coat to protect the finish. Use decal setting solution to help decals conform to panel lines.
About the model set
- Model Set Boeing E-3A: The Boeing E-3A Sentry is one of the most distinctive aircraft in military history, with a huge rotating radar on the fuselage. This feature is the visual centerpiece of the model, so take extra care when assembling and painting the radar dome to make it stand out.
