Eric,
"Materials. I will use only lightweight materials such as paper, wood, rubber, plastic, fiberglass, or when necessary ductile metal, for the construction of my rocket." From the NAR safety code.
This is a fine rocket built with significant skill and attention to detail. However, this rocket is also pushing the limit of what "when necessary" means with respect to the use of "ductile metal" in the construction. Safety is also an important design consideration. The Defender MkII might be able to fly again after taking a core sample out of a soccer field or a child's head but I do not think that to be the optimal engineering compromise between safety and strength.
That said, with honest sincerity, I applaud your efforts to bring fresh ideas to the hobby.
I would be proud to design and construct such a rocket for my own use where I have complete control over the circumstances under which it would be flow so that I could mitigate risks. I don't think I would ever kit a rocket like this where the judgment and skill of the builders will necessarily be an important and uncontrollable variable. It is not just an issue of legal liability, I pray for tort reform, it is a matter of conscience.
Regards,
Richard
