Are the, uh, "drag pads" canted to make it spin? Just curious.
Cool! That reminds me of the classic Centuri Satellite Killer, it has no nose cone. The dish is a REMOVE-BEFORE-FLIGHT thing.

I like watching my Quinstars spin on their way up. Adds a fun swooshing sound.I haven't decided yet....

Don't know off the top, will check at next opportunity.
This will be much more durable than the fiber fins and pads of the Satellite Killer.
And the draggy design will mean you can load it up with a big motor without fear of losing it.
Lots of noise, smoke, and fire, and oohs and aahs from the crowd.
Use a short delay or the chute may not have sufficient altitude to open.

After the second flight. She will be rebuilt. Faster, better, str.... Never mind.
After perusing your companion thread......
An off the shelf kit that's also a hoot to fly on G motors is the Rocketarium Turbo Vortico.
At the risk of being repetitious, here's a launch shot:
And of the same genre is the LOC Cool Spool. 29 mm motor mount.
Launch it on a Black Jack, lots of smoke, noise and fire.
Wish I had a launch pic.

All great for a smallish field.
Cheers.
Turbo Vortico is great fun, I saw KenECoyote fly one on an F15 and it was great. Really builds up a fast spin, and that helps it come down more slowly. Would be spectacular on something like an F10 with really long burn.
That reminds me of the estes blenderz!
If going with heli recovery and no chute leave the ejection charge off and tape over the charge well.

I would advice in this case AGAINST making it spin. Put the Drag Pads on flat, specifically no canted angle.Are the, uh, "drag pads" canted to make it spin? Just curious.
I would advice in this case AGAINST making it spin. Put the Drag Pads on flat, specifically no canted angle.
Rationale:
If the allow this to spin, it may spin very fast (maybe not, the radial fins may prevent it from going TOO fast).
This means it will impact Terra all too often Too-Firma with potentially considerable angular momentum.
And since you have no airfoils on this, spin gets you little if anything in terms of lift.
Not sure if you are gonna use a chute or not, it is gonna be a pretty tight fit but if you can get one it I would recommend it for this size. Even a small chute will help, as the model itself has significant drag, but as
@kuririn said, you will need a very short delay.
Anyhooo, even it lands motor mount first it is going to tip over until one of the drag pads hits the ground. If it is ROTATING at significant angular velocity, that will be significant kinetic energy that has to be dissipated suddenly to the ground, high probability of breaking off a fin.
I have experience with this as it is a problem with Helicopter rockets.
Names? I dunno. GeoSat is overused. Centrino? Soliton Sailor. Phoenix Rising? Tachyon Deflector?
It's a nice, clean design, should be a nice small field rocket. If you fly it as a pure saucer with no chute, you'll need a motor that you can remove the delay charge, I think. Otherwise highly likely delay will go off after this puppy has already landed. That tends to be frowned upon.
I don't think that's a real concern. If my Quinstars are any indication, these sorts of things don't tend to spin very fast, and by the time they land they're barely spinning at all. I'd also expect it to be much more robust than the typical helicopter rocket.
