Looking at the design now, I'd also recommend "silkspanning" the root edge/body tube joint, as is suggested for booster stages that tumble, etc. That would help beef things up, as well.

I looked for a line drawing example in the Rocketry Handbook as well as the NAR Member Guidebook, to no avail. Instead, I substitute my attempt on my Estes Der Red Max as a humble example. Hope this helps!

In the old days, they would use peel and stick address labels to beef up the fin/body tube joint.

Default Pegasus 0806 on "The Other Forum"...

I started a small thread on the other forum "a few years ago" on the Estes Pegasus #0806 where I posted a 1:1 Rocsim file as well as BT-55 and BT-60 upscale Rocsim files. Reposted here in case you (or anyone else) would like to experiment with them.

Silkspan? Can you still get Silkspan? The last time I used Silkspan was over 30 years ago to cover a Comet British S.E.5.

My LHS still carries Silkspan, Silk, Tissue, and Dope.
