If you send me the file, I might have a ramjet cone to fit it.
Truly awesome looking. I'm always a sucker for the designs that don't have stability written all over them. That's gonna need the BOMARC nose weight kit. Don't drop the nose cone on your foot.

I was wondering how many people were in both this forum and the Facebook group. This is the aforementioned Robert McNamee w/ the above model - lakeroadseter (is that you John?) thanks for sharing this over here...
I decided to put the larger fins on the rear and smaller in the middle to make things more stable but the rocket flew so straight that I think I could have gotten away with the large fins in the middle (which is definitely part of the look for this rocket). Easy enough to 3D print another set of parts and make another someday...
Here is the maiden launch:

I like it. I was looking how to build one in Rocksim. Flies on F-composite motors, no 3-d printed parts. Fins aren't quite "scale" though.

So we know the rear of the body is bigger in diameter than the front...

IF the sketch below can be trusted to be correct, the nose cone and a section of fuselage are straight, then from there it's a conical section all the way to the tail. Otherwise there would be a vertical line drawn, wherever other body sections went from straight to conical.

For sure!A swing test should help you to determine how much nose weight is really needed.
@lakeroadster -- your original mock-up has the ramjet tubes open, which seemingly could act as additional "finnage", making the rocket more stable than OpenRocket thinks it is, because I do not believe OpenRocket takes into account "tube fins". However, I also think the tubes are too long to act as fins, but only a swing test will tell for sure.
I notice a lot of the other attempts at this design show bigger fins at the bottom than at the center, making them "semi-scale" models. But that's artistic license to make it flyable in real life as a model. Either way, it's a nice design, very shocked there's no kit produced of this particular device, as I suspect every rocketeer would love to have one of these in his fleet.
