I am building a set of rockets based on the Rocket Vision rockets form years ago. I am converting the build to include 3d printed parts. Any interest is the build and build threads?

The answer is "yes" by default.

I'm not familiar with the Rocket Vision rockets. Can you give pointers (or pictures) to the ones you're thinking of?

Yes.
(the enthusiasm behind the "yes" is positively correlated to the weirdness of the design, and the quantity of frivolously shaped fins).

Can you post a few sample pictures of the designs on which you are working?

I am working on the parts. My first test flight was nto exactly stable on the Machbuster. I think I have too light of a nose cone. I will test it in June and post the files. Here are some images from a google search. It has a 24mm motor mount.

Interesting - looks like a mini-LOC-Nuke:


Are you printing both the nose cone and the fin-box?
Any motor retention contraptions?
A tail-cone?

If it works, any plans to sell the parts?

Anything is possible. It is near minimum diameter so probably no retention or tail cone. Tape used in the original. I already have a fin can and nose cone. I also have rail and rod guides.

You know, the more I look at this, the more I realize quite a few rockets look similar.

I still have a Rocketvision 6-Pack in the bag I need to build some day. For those unfamaliar with Rocketvision:


They made 'rugged rockets' that used phenolic airframes and G-10 fins, which was unusual for small rockets back then. They also made a very nice launch pad called the Quad-Pod. I have/had one that had the aluminum legs which did not do well under the thrust of an M motor. (They were later sold with steel legs.) But the head is very rugged so I attached it to a more robust set of legs.

The thing about that fin shape is it is "almost" impossible to get it to flutter if made with any reasonable material. So it's used for a lot of high performance rockets. The normal clipped delta doesn't need to be as wide since it can have a longer root to increase area without it being nearly as wide, but does need a bit more care in material selection and construction. At least that's what I've come to believe after some research: the farther away you move from a rectangular shape, the less likely the fin is to flutter.

I too have a Quad-Pod. It has served me well for years. I have not gone over G power on mine tho... Launched mostly at home with it.
Mine is the early version though where the legs were more vertical. Later, they changed the design some to flatten and widen the stance of the legs. I'd like to re-engineer mine to this style, but it doesn't get used much anymore...

I have a quad pod and would love to have them remade. I am not sure who could make the parts,
