Default Stellar Lance Corporal info?

Anyone got a parts list/instructions for the Centuri Stellar Lance Corporal? It appears eRockets has the fin set but I can’t find body tube sizes, etc - not much available on the net.

Thanks in advance!

Length: 18.5"
Diam: .759" (ST-7 tube)
Streamer recovery

Two stage sounding rocket. Apparently it was made available only to Centuri's mail order customers, so it did not appear in the catalogs, only in their newsletter. With the fin set from erockets and the above information, should be easy enough to clone.

From the January 1975 Centuri Rocket Times:

Let us know how it turns out.

Bill,

Did you find anything on this? Please let me know.

I think I have some printouts of specs that Carl originally had on the Semroc website.

EDIT: The info on the Lancer upper stage is still up:

Nope - all I have is the Lancer info on the Semroc site.

Would appreciate anything you can provide!

I would appreciate anything you find as well.

It looks like the nose cone is the rounded BC-730P. The Semroc parts list calls it BC-730, but there is only 730G and 730P.

Newbomb,

I agree completely. The BC-730P is a direct substitute for Centuri's original PNC-76.

Bill,

I looked through my old printouts, but there wasn't anything else listed for the Lance Corporal than what little is still on the old Semroc site.

However, I think we can approximate the L-C nonetheless.

I recommend adding two ST-730s (one for the payload section, the other for the booster stage). You'll need a BTC-7 connector for the payload section, and an HTC-7B (don't forget the "B!") for the first stage.

(I also recommend substituting a single ST-790 for the original Lancer's ST-760 and ST-730 tubes. It'll save you the original internal HTC-7 connector.)

Attaching the first stage to the sustainer could be tricky, though. I recommend taking a look at Centuri's Black Widow to see how it was done on that model.

Granted, the B-W first stage body tube was 4" long instead of 3", but at least that's a start.

Please note the excerpt from my current documentation project below. Thanks!

Bill and Newbomb,

I remembered this post of mine from July 2011. Granted, this is a 1.37X ST-10 upscale, but it's the best I can come up with spur of the moment.

I'll have to do some additional research to see if I did a 1.00X version.

Sirius Rocketry www.siriusrocketry.com offers hollow-cast polyurethane resin duplicates of that and other "Type C" (and "Type E") plastic nose cones, as part of their "Moldin' Oldies" line (see: http://www.siriusrocketry.biz/ishop...oldin%27+Oldies ). They make more than they list on the "Moldin' Oldies" page (I have one of their resin duplicates of the Lance Corporal's #7 tubing nose cone, and other unlisted [on their website] "Type C" duplicate nose cones [here are the "C" nose cones' designations--with drawings of them: http://www.ninfinger.org/rockets/no...a/72cen060.html ]). Also, I'm not being 'cutesy' by using the abbreviations "Type C" and "Type E"; Sirius has to do that in order to avoid trouble with those companies, which are now one company. As well:

The X-7 rocket in the Centuri Power System Outfit (see: http://forums.rocketshoppe.com/show...p?t=8784&page=3 and http://www.ninfinger.org/rockets/no...a/79cen008.html ) was essentially a Lance Corporal, and Semroc sells the fins for the X-7 http://www.erockets.biz/semroc-lase...et-sem-fce-ps7/ and the larger X-16 http://www.erockets.biz/semroc-lase...f-sem-fce-ps16/ rocket.

I hope this information will be helpful.
