40 Inch Rocket W/ 4 Estes Engines

thingiverse

This is an incredible 4-engine rocket! It requires 4 Estes B or C engines to take off. We recommend starting with a base that has 2 pole attachment bodies, then adding one fin body and a nose cone for maximum stability! The suggested rocket stands at an impressive 21 inches tall, while the one showcased in our video is approximately 40 inches tall! Parts are designed to fit seamlessly together; simply glue them into place. For those who want to get creative, here are some general rocket-shaped suggestions: cone, fins, pole attachment, and base. You can mix and match these components to create your dream rocket! Want a single-engine rocket instead? Check out this amazing design by NEATman on Thingiverse: https://www.thingiverse.com/thing:13616 Important safety notes: * This rocket uses FOUR engines, which means it packs an extreme amount of power. * For safety reasons, please use the same type of engine throughout the entire rocket. * Only use Estes B and C rocket engines for optimal performance. Watch our video explanation to get a better understanding of how this incredible rocket works: http://bit.ly/Rocket-Video When launching your rocket, we suggest doing so in an open field for safety reasons. This rocket is likely to melt mid-flight due to the high temperatures reached by the Estes B and C engines (up to 130-180°C or 266-356°F). Stay far back from the launch pad and consider wetting the grass beforehand to prevent any fires. To protect yourself, we highly recommend using a cardboard sheet as a shield in case the rocket tilts. With four engines on board, there's a higher chance of tilting, so please take this precaution seriously!
