I tried cloning a Soaring Eagle many years ago (it was a pain locating those BT-51s), but never finished the project. But I figure now would be a good time to finish it off. I've built most of the rocket already: the booster/pop pod, the tail section, and the wing support assembly. But now I have some questions after looking over the JimZ rocket plans. I refer to page 1 of the instructions and its listing of parts:

1. The pattern sheet (A) that goes underneath the main body tube. Is that cardstock, or some other kind of paper?
2. The main body tube (D) is a BT-50, but the length isn't specified. So does that mean it's 18"?
3. I bought a PNC-50SP from Moldin' Oldies. Does that weigh about the same as the original Estes nose cone?
4. How long is part (Q), the shock cord that attaches to the wing spars? Is it the usual 1/8" wide?

Thanks in advance for the help!
