That's the best name that has come to mind. No pun intended.
Started with the tube. I think it was from either a roll of food saver type bags or maybe butcher paper. It's thick and heavy-ish, but happened to just have the same inside diameter as BT-55. I had an extra conical nosecone in the parts pile and plenty of other stuff to make this reality, quickly.
The first bit of fun was working the nosecone with such a fat tube. I considered adding a small piece of normal BT-55 and a long coupler and adding a transition to it. Then I dug through my styrene supplies and a piece of square styrene around the shoulder of the nosecone just happened to match the outside diameter of the tube. Ok, I can work with that. A bit of sanding on the front edge and some Bondo and we have a more workable profile.
The name tells us this is meant to be brought down in a hurry. So, I made a fin profile very similar to an Estes Hi flier. Tinkering in Open rocket accidentally got me there. Wanted the fin to be positioned a bit ahead of the rear end of the rocket and not sweep to the rear. These gave decent stability without requiring much nose weight (which will be about 12g). I may need to clip on a couple more grams with a 24/60 reload if I get crazy.
Fins are 3/32 basswood, papered. Still light and seem quite strong. Recovery will be by mylar streamer.... probably 5x50" or so.
I only went with a 24mm mount so I can go through the wall fins.....but there could have been pretty stubby tabs with 29mm. Cheap flights are better too.
Sims to 2100' on a F24 and will fly great on the 24mm Q-Jets, but I suspect it'll commonly eat D12-5 s and E12-6s. It actually sims ok on C5-3 and C11-3 motors to about 300'. Got quite a range this can fly on.
Not sure how I'll paint it yet...
