I added more and more stuff and all it theoretically needs is two elastic bands. What a kludge.
No hypothetical worries here. It is good and nose heavy. Tail weight helped. Didn't add more as it already needs repair. I really don't want to add a bunch of weight so I think I'll extend the area of the canard. It may still just be a throw toy for the grandrocketeers. Or a chew toy for my dog.
