Rocket Ship design. What style is this?

Yes, I'm currently cutting foam for a S8 rocket glider. May I inquire what your thoughts transpire?

I have two foam cutting bows which is what I use to make foam glider wings. I have thought of doing that for rocket bodies but saw too many problems such as cutting a smooth arc and one cannot pass over a previous cut without making a messy blob at the intersection, etc. I have thought of chucking a piece of foam to my lathe and sanding it to shape but one can't make a dozen and have them all the same, plus a resilient surface finish is non existent.

Currently I'm considering straight fibreglass walls with no foam fill. It will likely be heavy and not as robust but would be cheaper and easier to make. I really do prefer the moulded foam filled body for its strength and precise shape.

I shall continue to noodle on this issue. Any suggestions are welcomed.

P.s. I've have had communication with Rick Vatsaas in the distant past.

As for techniques, there's a picture in one of the summer build-off threads of one that someone made from two nose cones with a shout piece of tube used as an "inside out coupler." It was posted as an aside, so there's no real detail. It wasn't as fat in the middle as the iconic ones, but one might be able to find (or make) shorter ratio cones. If the straight section is too long, you could cut the shoulders down until there's only a very little bit left, just the minimum for gluing. The tip is cut off of the aft cone, obviously.

I have something similar carved from balsa. I flew it once but it's just too fragile for rear ejection. I might try and make a mold from it eventually.

I only have primer shots on my phone.
