The Spartan kit (KD-3, Stellar product line) was a balsa fin version of the Screaming Eagle.

Back when Lee Piester was trying to start up a new rocket company (1987) called Enertek, one of the kits was to be a 2.5" diameter Screaming Eagle-like kit with a short boatail.

I managed to get it replaced with the INITIATOR!

Bill,

Did your Eagle come with a 12" or 16" chute? Was it black & yellow or red & white?

Red & white and I believe it was 12".

Yes, but I didn't get a drawing of the fins like Tim just sent.

Buzz, pull Tim's fin drawing out of this thread to include with Bill's scans that he sent us for this set. Give me an ACK when you read this. Thanks.

I stayed up all hours of the night last night looking through all the old Centuri catalogs at Ninfinger's. Why? Well, we all do it from time to time, but I did it because my Screaming Eagle just didn't look right to me.

It was obvious when I looked at the first pic. All the images show the upper roll pattern with a white background instead of silver. I looked at several other catalog shots to see if any looked like they had the silver backed roll pattern, but none really did. I don't know if they built a catalog model that way on purpose, or if the silver bleached out in the photos, or what.

At any rate, I think I'll build a paper and balsa clone with decals having a white background. My build list is already about 20 years long, but what the hey. It will be a bit of a pain to do the fin decals. I don't really like the results of white decal paper. Any dark background shows through the material. I'll probably mask off the proper size area and leave that white when I paint the fin area, then put the decal over it.

I also worked up the balsa and paper version, but I think you're going to be disappointed in the performance...

All of the deployment velocities are above 23 FPS...

Nicely done, Craig!


Two words: "Nose weight." (Oh, wait, if I read further down the thread, I see you already thought of that. )

I remember being especially amused when I read in the rocket's original instructions, "Even though the Screaming Eagle doesn't pass the swing test, this design is still quite stable."

IIRC, I lost my "SE" to a Rocket-Eating Cornfield on a C6-5. Come to think of it, the wind was blowing at a pretty good clip that day, too...


Cheers,

--Jay

Actually, if Tim could scan the plans that would be great. Sorry Bill, but your plans have some major stains on them and I've had a hard time cleaning them up. Tim's plans appear to be mint condition.

The plans that came with the kit were for the Powr Pad. The Screaming Eagle plans were missing. The Eagle plans and fin template are available at JimZ's website.

Powr Pad will do then if it's not too much trouble.
