Estes CrossFire

thingiverse

This is a 3D model of the Estes Crossfire, designed to soar up to 350 meters on a C6-5 motor. However, in reality, it only reaches an altitude of approximately 255 meters. The 3D printed version boasts a mono body design, where the fins, motor mount, launch lug, and body tube are all seamlessly integrated into one piece. When I launched this model at my school, it achieved an impressive height of 125 meters, closely matching the predicted results from Open Rockets. Notably, in an earlier test, I inadvertently inserted a B motor instead of the recommended C6-5, resulting in a failed ejection charge and a disheartening lawn dart incident into the ground. Upon examination, the rocket's nose cone had suffered damage, prompting me to apply masking tape to the top section to increase drag. In my opinion, if the original nose cone remained intact, the rocket could have potentially reached an additional 30-50 meters in height.
