    Does anyone know where I can get one (or more) of these kits?
    My 4H kids really like mine and would like to build one.
    Thanks for any help.

    Never heard of it. Who makes it? Do you have any pictures of yours?

    The Estes Seahawk (Estes #2149) comes up at least every two weeks on Ebay but expect to pay $25 to $35 for it.

    Long out of production and a very attractive model.

    The Nike like booster is also the basis for Estes Python (#2129) and the Old Pro Series Terrier/Sandhawk. Probably one of the prettiest scale kits Estes ever produced.

    The boys have good taste!

    Keep checking Ebay Rockets

    I saw one for the first time today. It was already built and hanging on display in one of our local hobby shops. It sure is a very nice looking rocket!

    Thanks again

    Wow, you all have it bad!!! :)

    That is a slick looking model and appears to be a knockoff of the real RIM-67. Airforce, have you ever considered cloning it with parts, balsa and plans...it would only cost you a few bucks and I am willing to bet the original plans and instruction sheets are at JimZ's website.

    Good luck,

    Carl

    I hope so!!!!:D
    So far no one has told me that its bad for my health..
    Besides, I don't smoke or drink so whats a guy to do.
    I have been very much like, (I forget who said it, but it was at this sight), one to try to build the kit exactly like the picture and have never really thought much about changing it.
    I'm not very artistic (stick men are hard for me to draw) so I think I'm one of those not geared towards turning a block of balsa into an SR-71. However,,,!!!:eek: I'm starting to feel a little more experimental, since being exposed to this forum.
    You guys are great and I really appreciate all the insightful commentary. Pictures, yes, thanks for all those pictures from everyone. For those of us that can get lost in a long terminology filled explanation, a picture is truly worth a 1,000 words. Best deal for us is the step by step with the pictures, not asking for much am I??:D
    Some of us catch the bug a little later and for many reason but at 50 I'm really enjoying this stuff!
    I'm trying very hard to get my 4Her's (9 to 13 year olds) to read this forum. I think I will assign them a current events item based from this forum.:cool:
    Thanks again Carl.

    Support our Military!!!! and thanks to all veterans.
    No I am not a veteran but I know who to thank.

    The Estes SM-3 Seahawk seems to be made up of parts Estes had laying around and it turned out to be a pretty good combo.

    The First stage and transition is based on the old Pro-Series Terrier/Sandhawk (my opinion it's one of the prettiest sounding rockets ever).

    The upper stage is nothing special but it seems to be a BT-55 with slots for the fins.

    The Booster was also reused by Estes to make the Python. This is another "Let's see if we can get rid of all our old parts" rockets by Estes. The touble is both of these rockets have become very dear to collectors because they are just plain COOL looking.

    The Lower stage fins might be kinda tough to duplicate since they are each two piece plastic and very thin...maybe 1/16" ply?

    The diamond shaped profile might be tough to duplicate...hey, if it were easy, everybody would make a clone of it.

    I've considered cloning the Pro Series Terrier/Sandhawk but I may as well do a scale model of the whole thing with all the dimesions from Peter Always "Rockets of the World". I do have an "opened" Terrier/Sandhawk i can get dimesions off of if anyone is interested.

    Here it is, someone already did it. It's in Rocksim 5.0 format I believe, but might be 6.0. If 5.0, you can download the free version and look at it. www.apogeerockets.com

    I found it on rocketreviews.com - got to use that first. Should be able to teach some basic rocket building with this one. Course, this is also begging to be upscaled for HPR :)...

    Have fun,
    Alan

    <raises hand> I served my 4 years in the Air Force and got out as an E4. I was stationed at Elmendorf AFB in Alaska. Brrrr...quite cold for a Florida boy!

    Airforce,

    As for the Seahawk, you should definitely look into using some power tools to create the balsa parts (nosecone/transition). As for the fins, it would be a matter of tracing and cutting patterns.

    Here's some info on using a drill to turn a nosecone:

    <a href="http://www.rocketryforum.com/showthread.php?s=&threadid=1198&highlight=eugenefl">Homemade nosecone</a>

    You'd be surprised at the outcome of what you can make with your hands.

    eugenefl, thanks for the nosecone info and thanks for your service.
    While I have you, do you know what a file extension of .rkt is?
    I click on it but I don't have whats needed to open it, its just a bunch of funny looking characters, you know the kind you get when you try to open a non-excel file with excel.
    Thanks for any help.

    Randy....

    That is a design file for RockSim, a rocket design and simulation program. It's probably the most popular of programs and you can get a free demo of it at www.apogeerockets.com .

    Also, I noticed you are in Ohio...you may want to try and make a launch here in Cincinnati...or check out our schedule for the BIG launches starting the 2nd and 3rd of November in Mechanicsburg. It would give you a chance to meet a ton of rocketeers from all over the state, myself included, and give ya a chance to shop at Magnum Rockets at the same time!

    Here's the catalog image of the SM-3 Seahawk #2149:
    http://www.dars.org/jimz/misc/98est34.jpg

    It was listed as a new item in the 1998 catalog,
    I believe it was still around in 1999, there was
    no 1999 catalog, and it was gone from the 6 page
    2000 catalog.

    I don't currently have the plans for the site so now I'm on a quest to find this kit. Is anyone willing to lend me one for a while?
