As far as Jewel's talents go I will dig around in my bookmarks and find his picture pages of tube rockets. The man is a building machine.
Hello, new member and what the heck is a goonie?
The Semroc Ruskie and Saki are patterned after the designs that were the inspiration for Estes Industries' Goonybirds. Estes took the concept and created their own designs. I'm not sure who actually designed the originals.
Semroc calls its versions "Groonies" or "grown-up Goonies." Not only are they less juvenile in design (although "juvenile" here is a relative term ), but they are also larger in diameter. Estes' Goonybirds were all designed around a BT-60 body tube (1.637" outside diameter), while Semroc's Groonies are based on their ST-18 tubing (1.84" outside diameter).
Excelsior Rocketry originated the idea of the "Goony-Bash" which involved making "goonybird" versions of well-known classic rocket designs. The Goony-Bash designs are "kit-bashed" from Estes' current kit, the Baby Bertha. The Baby also uses a length of BT-60 for its body tube, and it also uses the same nose cone as the original Goonybirds from 1973. In a sense, the Baby Bertha IS a Goony version of Estes' venerable Big Bertha kit, although it is not marketed as such. But the Baby Bertha is a bit longer than the Goonybirds were, and it features a standard, 18mm engine mount (meaning that it flies on A, B and C engines) in contrast to the original Goonies, which flew on 13mm "mini" engines. Nevertheless, it is a great basis for kit-bashing Goony designs. (The term "kit-bashing" means using the parts from a kit to make a completely different design.)
Although Excelsior's designs are kit-bashed from a Baby Bertha kit, not all of the Goonies that others have designed are kit-bashes. The features that Goony designs have in common are that they are either droll caricatures of existing kits, classic kits, or actual rockets, or else they are original designs that appear light-hearted and humorous or satirical in concept. Like their inspiration, they are usually based on a BT-60 body tube and a PNC-60L nose cone.
There are also "Super Goonies" which are either kit-bashed from, or resemble in dimensions Estes' recently discontinued Fat Boy kit. The Fat Boy itself looked like a Goonybird with a glandular problem, being a stubby rocket that used a BT-80 body tube (2.6" outside diameter) and a PNC-80BB nose cone (almost identical in shape to an enlarged version of the Goonybirds' nose cone). And now there are even bigger Super Goonies that are based on Estes' current Big Daddy kit, which has a 3" diameter body tube. (See Excelsior's Der Grosser Vati for an example.)
It is an interesting challenge to come up with a new Goony design that has not been done before, or in a size that has not been done before, that actually is stable in flight. People who have succeeded in doing so take great delight in posting their design's building process in a series of posts in this forum, and the rest of us take great delight in posting reactions to the design (always positive, BTW ). "Goony build threads" have become very popular here in the past couple of years.
To further illustrate, these were the original Goony Birds as introduced in 1973. There were other, earlier designs that were a lot cooler (Semroc has released a couple of them), but this is what happened after the Marketing Department at Estes got through with the concept. I should also point out that although each was made from a BT-60 - a bit shorter tube than is in the Baby Bertha - the Goonys were designed with 13mm motor mounts and flew on the A10-3T.
Could you make this post a sticky right at the top of the Goonie Forum. Great information for us new guys on what a Goonie is (or isnt :confused2: )
JimZ has scans of the fins on his site, along with instructions and decals, for most of the original Goonies http://www.spacemodeling.org/jimz/estes.htmI would like to create clones of those rockets since it is quite impossible to find them on eBay. I found plans but I have a problem with fin dimensions. Just body tube edge fin dimension would help a lot. So if someone has these: Galaxy guppy, Starsnoop, Missle Toe, Sky Shriek I would appreciate the info.
Welcome to my world... That's what prevents me from doing so many sims...Scans are ok. I am using his scans and YORF info but scale is problem. Just two models have comparable scale so size of fin can be determined precisely. Other 4 doesn't. That is why I need dimension of at least one side.
