No problem. You inspired me so much I actually ordered the nose cones and centering rings (CR-1013, 1020) for the Argo-C and my Mars Voyager (pictures here) from Semroc this afternoon! Cheers,

Thanks Jay, I am glad you are inspired and back in the mix of it. Craig and I are looking forward to the 500th design posting. Don't tell Craig but, I have already started saving a few designs for the next 12 Days Before Christmas 2008 . One of them is my version of the Black Hole Space Probe II. Your Pal, JP.

Mars Voyager -- Take 3!
Quote:
This one *doesn't* count toward the "Magic Number" since I'm updating it from 2006. I plan on building it with 3/32" balsa and "skinning" the fins with label paper. While the performance is slightly improved from using 1/8" balsa, *both* versions fly best using C6-3 (18mm) and E9-4 (24mm). +++ Mars Voyager. version 3 (Semroc parts list) BC-2032 Nose cone ST-2060 Body tube 2 - LL-320 Launch lugs 4 ST-530 Body tubes ST-10120 Body tube -- 12" L, 3.0" inside PR-1020, ST-2060 PR-1020 Paper Reducer (Transition)** -- 1.5" L 2 - CR-1020 Centering rings EM-710 Engine mount (protrudes 0.125") Includes: * 2 - CR-710 Centering rings * ST-730 Body tube * TR-7 Thrust ring (Engine block) * EH-28 Engine hook CP-160 Parachute Kevlar thread Elastic cord Fin set -- 3/32" balsa Launch lug standoff -- 3/32" balsa ___ **Not all parts available from Semroc yet. Motor / Max.

New Design: Cloud Splitter
Looks good Jay and thanks for the parts list .
I tried to post this design the other night but the net was soooo sloooow or maybe I had my tower turned to an UHF channel or something . Sunspots that muat have been it . This next design called the Cloud Splitter (Name inspired by Craig's Cloud Seeker) has layer fin design along with a ring tail. This fin method I used a few years ago on the Static Probe design th help reienforce the narrow pointed fins against flight tear off. I used a simular method on the Cloud Splitter to help reinforce the pod looking fins that are attached to the ring tail fin as these pod fins have only a 3/4 inch root area to glue to. This fin designs system is somewhat elaborate and may be time concuming to build but should be structually sound in flight. We hope . Enjoy and Thanks Again, JP James Pierson NAR# 77907 Cloud Splitter (18mm) Launch guide length: 36.0000 In MOTOR.................MAX. ALTITUDE...........DEP. VELOCITY A8-3..................211.02713 Ft..............2.3327 ft/s B4-4..................482.73157 Ft..............7.0144 ft/s B6-4..................488.82428 Ft.............11.2457 ft/s C6-5.................1019.38453 Ft..............9.8856 ft/s . |

We don't mind at all! Interesting twist to the idea of "tube fins"... Do you mind if we include this into the "official" BARCLONE line-up?
