That brings back memories! Great job, can't wait to see some painted pics. (Where's the drooling emoticon?) This was my first multistage rocket back in the '70's. Now you've got me wanting to clone it myself.

Nice-looking bare-bones model. I've got the parts to a clone cut out and just waiting for an opportunity... The white decal sheet is an easy and clean option, but where it falls down is color-matching to the paint you use on the remainder of the model. You'd have to get the decal color as close as possible first, then mix your paint to match the decal. If you have a newer Epson with DuraBrite inks, the latest Papilio papers claim to be compatable. Epson inks are waterproof when they dry, so you should be able to trim through the color areas for a crisp edge without having a tell-tale white edge from the decal. Trim MonoKote is probably the second cleanest option, but maybe the easiest option. Once you have it applied and the water has dried, shooting it with clear Acrylic ought to be enough to completely seal it to the surface. You still have to color-match your paint to the MonoKote...

Here's a pic of the 137% upscale I'm working on. All parts including laser cut fin set came from Semroc. I went chicken and put in 18mm mounts.

Buzz's Centuri Stiletto 137% upscale
Quote:
Sorry to resurrect this thread from a year and a half ago, but here goes anyway. My initial measurements (100% and 137% upscale) are as follows: Booster length -- 3.00" --> 4.11" (will probably round to 4.00") Main body tube -- 12.00" --> 16.44" (rounded to 16.5") Nose cone 3.00" = Semroc BC-730 --> 4.11" = BC-1041P I'll need to order a 137% fin set *without* the slots from Carl. (Were your fins 3/32" or 1/8" balsa?) And some HTC-10's, too. I downloaded the plans for the Centuri T-Bird last night, but I noticed that its lower stages are only 3" long: http://www.dars.org/jimz/kc-9.htm Anyway, here's my burning question: Since you put EM-710 mounts in your version, did you have to "gap" stage things internally? Inquiring minds want to know. Thanks, as always, and cheers,

Looking good. Your table looks like mine. I've got eight built rockets waiting for finishing. I hate sanding, so the winter weather has allowed me to put off painting, and therefore put off sanding for several months. |

Hi Jay, My fin set from Carl was 3/32 stock I punched two holes in the HTC-10 coupler. Make sure the holes are right at the joint so the gas is vented as soon as the booster moves. This is a mod you can add to any multi-stage model.

Stiletto Staging Queries
Quote:
Any chance you could take some photos of the "upper" end of the booster and the "lower" end of the sustainer so we could see the internal details? Thanks, as always,

To be honest Jay, I don't have a direct tube and HTC-7A coupler from the booster to sustainer. The distance from the booster motor to the sustainer is short enough that you don't really need one. The holes in the HTC-10 coupler are enough. I'll take a photo for you of the booster.
