Yep.. got one of those... EARLY in my time as a BAR... ( edit: Never named it yet. Any ideas? )
Wanted to build my own 95% fiberglass rocket. (Making tubes and all.) Decided on a tube fin with angled leading and trailing edges, so I could paint inside a contrasting color... 2.25"OD tubes, 38mm motor mount.
Well issue 1 was cutting the tubefins couldn't get the 6 to be even. Even after a few retrys. So intentionally made (3) approximately 1/2" longer than the other (3).
Looked "good enough" so epoxied it all together.
Now issue 2: The heavy wall fiberglass tubes I made, weighed a lot. So the rocket is very heavy, and NEEDS high thrust to get moving...
Issue 3 :Learned of the open rocket program. I modeled it in OR Ver19.03 with "experimental tube fin support" and found out it needed more stability. The heavy wall fiberglass tubes, and lots of Epoxy surfaces at the back, made the aft end VERY heavy.
Since then it sits in the corner of the office and I fidget with it a little from time to time. I DID learn a lot from it so the build was a good learning experience...
* I added a coupler and payload tube.
** payload tube is just long enough for the large parachute for recovery due to weight.
* Coupler has AV Bay for DD.
* Now it just looks "too long"
I should just finish it, and send it, but can't get the ambition to finish filing and sanding the tiny voids in the fiberglass weave. Then paint.
