Titans are a highly sought-after item, especially for its tank; However, some people, like Ryan from MTB, use the Titan as it was originally designed- Firing large rockets.
However, because Titan rockets are VERY expensive, how would you guys go about making a homemade one? I'm personally doing the R&D on making rings of craft foam and gluing them tightly around a piece of 1-1/4" PVC to ensure the shape and seal are good, but if you have any other suggestions, feel free to discuss the idea here.
