Yeah, it's rough, but I"ll just have to suck it up.
Here's a really silly one. Fins that are clipped washers, each decorated like a different kind of doughnut.
I hadn't even thought of that.That would suit your profile picture very well.
Fried.I dunno...that looks fully baked to me.
I like the standing wave (or traveling wave), it reminds me of the rockets made from styrofoam cups back to back. Would that be a bunch of transitions?

You know, some of the single serve cereal cups are just about the right shape. Also some yogurt containers.The two-stage looks like a fun rocket, I watched your ground testing videos. It seems like you're just about there, very nearly done. I think that your rear-eject idea ought to work.

Or maybe "Mach Diamonds"I think it needs to be called "Mock Diamonds". Especially with that color paint job.

Yeah, that's what I was seeing! I just tried to get too cute with the spelling.
The fin shapes were the starting point. Their sequencing didn't show up well in the renders and I added the color sequence to enhance the shape sequence. And then I liked it. The jigging would be, well let's say interesting. With repeated applications of the Estes grey jig one get to 12 but not to 24. Or I could settle for just the 12. Carefully place one by hand in between two of the 12 then use the jig for the remaining ones. It should work.Whew, building Colorburst would be an exercise in fin glueing patience. But it would be cool to see it built. It might be a neat effect if it rotated on the way up, especially with those fin shapes.
I had the same impression when I saw it complete. I was inspired by the idea of having the same cone angle on the body and the fins; with the all tail cone body it shouldn't look like a shuttlecock, yet it does.BTW since no one else has commented on it: I like Teardrops a lot. I kind of feel like I've seen something like it before, but I can't place where or when that might have been. It sort of makes me think of a rocket-ized Shuttlecock.
Rocksim. For scale, the motor mount is 24 mm (or is it 18? I did this one a long time ago and just got around to posting it) and it's minimum diameter at the aft end. It takes 20 g of nose weight to get to 1.0 caliber. At that point, the CG and CP are practically half it's length apart because the maximum forward diameter is so big. I'm confident that'd be OK.But it looks like it would be really hard to get stable. Joe, are those renders from Rocksim or just a CAD program? Curious where the CP ends up.
Standard approach in OR would be to add a phantom tube to the rear of the rocket, and mount the fin extensions onto that. I suspect that'll work in RockSim as well but you can try it and confirm.I don't see a way in RockSim to model the fin extensions that are below the aft end of the tube. I added them in Paint to the side view.
I am unsold on balsa plywood's strength, especially for something like this. Maybe basswood?and the fins made from balsa plywood to make their aft points a little bit durable; I tried modeling it with 1/8" birch ply and it was too heavy, giving a stability problem. Maybe 1/16" birch ply would be better than 1/8" balsa ply.
I was assuming that interior space was the issue. Erockets makes some nice long BT60 conical noses, but that'll leave almost no room in there for the laundry. I'm not aware of a readily available long conic BT60 nose in plastic.Any particular reason you'd prefer a 3d printed nose cone over a balsa one? I didn't check BMS, but seems like a conical cone for BT60 should be available. The other option is to use a plastic one, cut out the base, and then you have a hollow volume which gives you a bunch more space.
