I'll add my vote for PDF catalogs. It would certainly be cheaper to produce...

And me as well. If I'm not online, I generally just go by the pages I've saved off the website, which I update ever couple of months. But a nice, condensed PDF catalog would be great.

Thirty new balsa parts released by Semroc and we were never told in advance here at SVDT.

STOP the presses I am gonna call the Seattle PI, New York Times and Chicago Daily! This news of new parts is what I live for as a rookie designer. Very News Worthy, Indeed.

Another reason to go with PDF - by the time a printed (paper) catalog is ready to ship, the catalog is already out of date. With PDF, you could update the list several times in the year - quarterly (or even just twice-yearly) would be great for the kits catalog, and bi-monthly for the parts (which get added more frequently).

So much activity over here!

Well, to break in my copy of RockSim 9, I thought I'd revisit the Tetraphelion, taking advantage of some of the new capabilities of v9. I actually started from scratch on this design, but it draws a significant amount of inspiration from the original. Changes include the addition of 2 more side pods, a 24mm sustainer, and generally a much larger design (nearly a foot longer at 42.9", yet still weighs in at ~5 oz dry). Even with 2 A8-3's (deployment mounts) and 2 B6-0's (booster mounts) loaded, it still manages 34 MPH by the end of a 36" rod.

Length: 42.9"
Diameter: 1.34" (ST-13; Sustainer), 2.04" (ST-20; Booster)
Weight: 5.37 oz

Flight Data:
C6-0, C6-0, C6-3, C6-3 ---> E9-8 . . . . . 3056' . . . . . Dv. 33.3 ft/s
with a theoretical E9-7, Dv. 6.91 ft/s

B6-0, B6-0, A8-3, A8-3 ---> C11-7 . . . . . 1086' . . . . . Dv. 13.2 ft/s

That's a beauty!

If you filter out all references to Semroc motors from your simulations, and just go with "standard Estes or Quest" motors, you can post this one in the "Designer's Studio" thread and I can include it in the Master List. This would be a welcome addition!

Thanks;

At the moment, I haven't put any Semroc motors into my program yet, so as it stands, the file ought to be clean enough (Just Estes and AeroTech E9's, D21's, C11's, C6's, B6's, and A8's ATM). I'll probably just delete the reference to the original Tetraphelion in the rocket design description, but that probably isn't a huge deal in the first place.

I need to actually build some of these!

Your description included an A8-4, which is in the Semroc list (DECAP). Just a heads-up on such 'next-generation' hardware...

Oh, whoops!

I just ran through all of the posts here in our "private thread", and I've located no less than 29 designs which are not yet available to the BARCLONE Master List. The biggest reason is the use of NYA Semroc motors, which we still cannot discuss away from the SVDT.

If you will locate your respective designs, try to re-motor the simulations with currently-available Estes-Quest-Aerotech motors and see if you can get reasonable Dv numbers and launch guide requirements less than 40" and 30" (for 48" and 36" rods, respectively). When you are satisfied with the results, please re-post them into the (new) BARCLONE Designer's Studio 2009 thread, and I'll get them added to the Master List on our Wordpress site.

Here's the list:

1. Venus Explorer
2. Micro Hustler
3. Hypertuse
4. Tiny Ivan
5. King Vidar
6. Mach I Dart with Thruster System
7. Lune R1 Plus 1
8. Skeeter
10. Mini Tom
11. Korviena
12. Triplet
13. Tensor
14. SLS Cyber III
15. Tetraphelion
16. Zondakhod
17. Nike-Smoke 13mm
18. Talos
19. Micro Bertha Probe Mk I
20. Micro Bertha Probe Mk II
21. G Harry Stine Basic Design
22. Deimios
23. Rayfinder
24. Zoot
25. Sky Master
26. Baracuda
27. Nova Hi
28. Hyper Jett

This represents 28 designs that will get us closer to the 600-design milestone. A few other designs are dependent on motors and components that don't yet exist, so they're not included here. But if these can be re-worked, let's get them available.

Thanks!
