Estes Solar Warrior (#3225) Build, Part 7, Observations
These broke with a light pull. I'll replace them with all cotton embroidery thread.
The reinforcement rings turned out to be paper. Paper reinforcement rings are worthless and don't strengthen the shroud line tie area.
These will also be replaced with plastic Avery rings.
On the far left is the brown tube sprayed with grey filler/primer. The white tube is beside it on the right. Look close and you can see the white tube is rougher after sanding down the CWF seam fill.
The inset picture shows both tubes again after the primer/filler was sanded down. Both tubes feel equally smooth. But, if you lightly squeeze the tube ends between your thumb and index finger the white tube feels a bit weaker. It's a guess on my part, but the white tubes may contain a higher content of recycled fibers.
