    I have a nose cone question. The nose cone on this rocket has a stepped section with a flat on the end of the nose cone. I had planned to "make up" a stainless/aluminum nut and fill the rest wit epoxy, etc.

    Is there a special aluminum nose tip for this rocket? I haven't found much.

    I have one. Not aware of what you are looking for. Just checking.....are you aware that the step and flat on the end is scale?

    I didn't know that. I've only seen the small (Estes) versions in person (in the package).

    After looking at airplanesandrockets.com, I found a detail, and still would have assumed there was a cap, although it does seem to *only* show where the point would have ended...

    The threaded rod from the bulkhead to the front would make me feel better with a nut on the outside, being a belts and suspenders type. I didn't know if there was something made for this.

    I'll probably use an acorn nut, thread a bushing, or something. Durability is more of a concern to me than scale looks. It will be painted non-traditionally.

    Notice that, even per your drawing, the full size had a 2" diameter tip. This is the pipe that leads to the TiCl4 tank that produces the smoke. A 4" is about 1/4 scale so the tip should be about 1/2" diameter. I used to have an Enerjet version, about 1/8 scale that had a tube (1/4" diameter) leading to tracking powder that vented out one of the cover plates near the base of the cone. (Didn't work well :( and was unstable with no powder on a F67.)

    Thanks for posting this drawing... I've been looking for details about the base of that NC for quite some time - particuarly the length of the transition from body diameter to NC maximum diameter.

    As to your original question, I believe the tip of the actual rocket has this flat/stepped tip, as the diagram shows... It does not come to a full point. Of course, that doesn't mean you can't make it that way...
