Model Rocket Building: Estes Quinstar #7241 Build, Part 3, Balsa Prep (2016-01-28)

Model Rocket Building: Estes Quinstar #7241 Build, Part 6, Fillets and Bulkhead (2016-02-03)

Flip over the cage so it can be pressed down and even on the tabletop. Before adding glue, the BT-50 was slid into the center cavity so the pentagon shape would be even. One of the centering rings ... [Read More]

Model Rocket Building: Estes Quinstar #7241 Build, Part 10, Undercoat and Red Paint (2016-02-09)

The assembled model was hit with a light coat of gloss white. I wanted to use Rusto Red Metallic. It's a bit transparent and would need the white underneath it. I thought I might get by with ... [Read More]

Model Rocket Building: Estes Quinstar #7241 Build, Part 11, Finished (2016-02-10)

This was a fun build and turned out better than I thought it would. With just the flat, upward facing pieces filled and smooth the model looks good. The 24mm engine conversion was easy to do. Will ... [Read More]

Model Rocket Building: Unstable Quinstar? (2016-11-05)
