I have a built Astro sitting on my shelf here - kit #1937.

The model is BT-20 based, not BT-5. The "grey" in the decal is actually silver. The fin root edge on my model is 2" exactly; fin thickness is 3/32". Model uses a PNC-20A nose cone.

Hope this helps.

Thanks for the assist on both accounts. I don't know why when I saw that it was min. dia I assumed it was BT 5 based, but I did.

Thanks for the help.

I'm trying to screen print some of the Astro decals and am having an issue with the pdf's involved. The fin size seems extremely large for a 13mm minimum dia. design. and the orange color stripe would wrap around the body tube one and a half times. While this may be the case, I would doubt it.

I would appreciate it if someone who has an Astro could give me a root edge dimension for the fin, if possible. Also, as mentioned above, Blackshire stated that the decals were orange and gray. I have an idea that the gray in the scans was just to show the decal and that the actual color is white. Can anyone confirm this?

Thank you.
While John Brohm (Thank You!) resolved this matter in Reply #21 (on page 3 of this thread), the Astro decals *do* look different in two different depictions shown *here* (see: http://plans.rocketshoppe.com/estes/est1937/est1937.pdf [its fins are pretty big, too, as you had wondered about in your posting above]), and this phenomenon could "throw off" decal color perceptions for other OOP kits that folks want to re-create, too (especially if the would-be "re-creator" never had such a kit, or never saw a built one). To illustrate this phenomenon using the Astro's simple decor scheme:

On the Astro's kit insert card (as shown in the above-linked scan), the "swept block" fin decal is white, but it is gray in the scan of the decal sheet. But as John Brohm reported (and showed, with attached photographs of his Astro in Reply #21), *both* "swept block" decal colors shown in the scan were wrong, with that portion of the decal actually being silver! With the more complex decor schemes on other OOP kits, it would be easy (if one didn't have an actual example of the old kit, or a good color picture of a built one, or an older model rocketeer's description of the actual decal color or colors) to make decals for a reproduction of an old kit that are the wrong color(s), without even knowing it.

Hmmm...a down-scaled Astro, based on BT-5 tubing and the Gnome kit's plastic nose cone (which has the same 4:1 tangent ogive shape as the Astro's BT-20 plastic nose cone [which is also used in the Viking and Wizard kits]), would also make a nice kit for school and youth group projects, as well as for individual model rocketeers. The BT-5 Astro could use 1/16" or 3/32" thick sheet balsa fins or 0.050" thick fiber ("Beveridge board"--Centuri spelled fiber as "fibre" to be fancy :-) ) fins. (Computer printer paper-laminated 1/16" sheet balsa fins would look great and make the fin finishing & painting much easier, while also producing tougher fins.)

I wouldn't necessarily rely on an old rocketeers memory of the color of a decal either. I know in my own case, I believed the "orange in the decals for the Andromeda were a lot brighter than what I have found out. I actually mow believe the orange was closer to the red-orange of the Astro's decals.

I never had an Andromeda kit, but its depictions in the Estes catalogs http://www.ninfinger.org/rockets/no...a/76est026.html showed red or red-orange markings on its overall black hull. Since the catalog illustrations were composite color (also called spot color), it's possible--although it doesn't appear to have been in this particular case--that "in-between" or "combination" colors (such as red-orange) might have been represented somewhat inaccurately, at least in some cases. Also (especially in non-scale kits), might decals' colors have changed slightly over the production lives of long-produced kits, due to changing decal pigment availability and/or price (since Estes' kit decals were and are made in large quantities)?

Blackshire,
I don't think I have the red-orange quite right, but I'm getting closer as you can see here
