Hi
Jay, Craig, Bill
I have been planning to build tau zero for sum time, so finding that it has instability problem is no big deal. Os i order the parts and body tubes, rocket Kits from semroc Seeing that is going be my first (semroc?) non estes kit (the Estes kit are starting go down hill) (Estes space ship one sucks, and 36DD? ok ho the designer at Estes ho go to hootes, just jugging or is joking). Well if I don't include all my own design and all the flis kits I have. This is going to be fun rocket to build and love to see semroc make it one of there kits. (BIG HINT) Next on my build list will be Prometheus.

Whether or not the real rocket, once it's built, has the same margin of stability as that predicted by Rocksim is the real issue. And apparently Jay's *real* Tau Zero was not as stable as Rocksim predicted it would be. (Jay, I don't recall if you're using the Rocksim or Barrowman stability calcs. If I recall correctly, the Barrowman calcs are generally more conservative than the Rocksim ones. That is, the Barrowman calcs generally say a design is at least somewhat less stable than the Rocksim stability calcs do.)

The Next Step
Quote:
I just got done ordering some bigger screw eyes (SE-14) as well as nose weights (WL-7) from Semroc. The Tau Zero has taken more test flights than I initially expected, but I think the "real world" experience will pay off for the rest of you who decide to build one. Quote:
I ordered the SLS 175% upscale of the BC-760 nose cone, too. Cheers,

Apparently I've already voted for it because when I tried tonight it wouldn't count my vote. I also noticed that someone has been voting for Semroc to produce currently available Quest kits. The Big Betty even has six votes. Isn't that kinda stupid?

Makes perfect sense to me. They're just saying Carl could package a better kit version with better-quality components than Quest has been doing, even if the price might be a little higher. Think about Quest's parts compared to Carl's...
