Here's an idea to complement Craig's "Scrounged-Up Designs" thread: Classic (instead of ORIGINAL ) model rocket designs updated for the 21st Century.

I approximated this RockSim file from the FSI "Orbit" PDF at "Ye Olde Rocket Plans" (YORP):
http://www.oldrocketplans.com/fsi/fsi1006/fsi1006.htm


FSI Orbit (using Semroc "FSI-size" parts)

BC-8F28 Nose cone
SE-10 Screw Eye
ST-8F90 Body tube
CP-12 Parachute
BR-8F11 Reducer -- 5/8" hollow
ST-1190 Body tube - cut to 8"
LL-122 Launch lug
Kevlar thread
Elastic shock cord
"EM-711" Engine mount*
ST-730 Body tube
TR-7 Thrust ring
2 CR-711 Centering rings*
3/32" Balsa Fin set - not Aircraft Plywood

*These parts not available from Semroc just yet. Please check www.semroc.com.


Motor / Altitude / Velocity at Ejection

A8-3 -- 233 ft. -- 5.30 fps
B4-4 -- 524 ft. -- 13.30 fps
B6-4 -- 530 ft. -- 17.45 fps
C6-5 -- 1095 ft. -- 15.80 fps
C11-5 -- 967 ft. -- 33.15 fps
C11-7 -- 978 ft. -- 30.11 fps
D12-7 -- 1723 ft. -- 9.72 fps


(Steve Naquin, who mistook my Prometheus design for the FSI Orbit, is partially to blame for inspiring this particular project.)


Thanks, and enjoy,

--Jay

I love it!

That's just what we need, too: More plans to build, more projects to spend time on, more parts to buy!

How else are we going to stay out of trouble?

Sometimes I have cool ideas and "I just have to GET THINGS OUT OF MY HEAD SO I CAN *THINK* STRAIGHT!"
...he said, panting rather strenuously.

(I feel much better now. )


Glad you like the idea.

But isn't this just cloning by another name?

Sean

No, it's Classic Updates. Makes sense to me. How are you going to get FSI parts to clone an FSI bird. Or Centuri for that matter. They don't exist anymore.
Count me in!

I do believe Carl's wonder machine will be churning out FSI clone parts in the not too distant future.

He (Carl) is already churning out FSI clone parts isn't he ?

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, and HAVOC !

He's got some now, yes. I believe we're going to see many FSI clone kits in the future though.

Alright Jay, I'll take the blame

I downloaded and saved the FSI Orbit file. I was big into FSI. My interest in FSI is evident in these pictures I posted in the "old pictures of old rockets" thread a while back that I built while I was in high school. My two Orbits, Maverick, Penetrator, OSO are also there with a couple of Mach-1 Darts. There were two versions of the FSI Orbit. The original was short and the later one was longer. I had built both.

I wish I still had some of those FSI originals and I will recreate a few with Semroc parts.

Thanks for the file Jay!

Wow!! You guys are far too picky. If the tube from SEMROC I'm using to build a Centuri Chuter II is the same length and diameter as the original, and the nose cone from SEMROC meets the same specs as the original, and I use the fin pattern from a scan of the original fins, then as far as I'm concerned it's a clone of the Centuri Chuter II kit. Same goes for the FSI replacement parts I'm using from SEMROC to recreate the FSI kits.
Now, I'm not going to go as far as making sloppy cuts on the tubes or intentionally sand the shoulders of the nose cones and transitions so the tubes sit at an angle like the original kits, so maybe you *can* fault me there
