![]() The SLS Lune R-1 is an upscale of the 1.04" diameter Semroc Lune R-1 to LT-175 tubing. This design shares many of the same parts as the Semroc SLS kits Aero-Dart & Explorer and includes the same removable engine mount for 24mm or 29mm flights.
I cut the fin set from basswood stock and used the same tab measurements to fit a Semroc pre-slotted body tube same as used in the SLS kits. This design uses LL-320 3/16" launch lugs although my test model used 1/4" lugs since that size is prevalent at the launch site I flew at. Lune R-1 upscaled color vinyl graphics by Graphix & Stuff. Some build pictures are included below. Pictures of the first F42-8T test flight in these links: http://tinyurl.com/8a4x7j http://tinyurl.com/axun89 http://tinyurl.com/7neq55 http://tinyurl.com/9troup The F42T EconoJet using the 8 second delay proved to be a great choice for a picture perfect deployment on it's first flight. D12-5 & E9-6 flights would require a minimum 48" rod to get up to speed and those selections would be great for demo flights on a smaller field. Length: 41.095" Diameter: 1.840" (LT-175) Span Dia: 7.146" Weight: 6.807 oz D12-5......529'......Dv 17 FPS......48" x 3/16" rod E9-6........875'......Dv 29 FPS......48" x 3/16" rod F42-8....1,861'......Dv 3 FPS.......36" x 3/16" rod Thanks for looking! ![]()

![]() A great version of a great rocket, Steve. The Lune-R1 is perfect for SLS upscaling! Nice job!

Craig, I'll focus on the standard Semroc balsa reducers (transitions) and follow your lead regarding including both a normal and reversed part. I was just setting up the base template with decimal precision when I saw the file you posted. I am going to use it as template for basic transitions. I will probably post file later tonight for review. After working with the .CSV files, I believe this is an area of Rocksim that the developers should look to update. Maybe a move to XML similar to the design file format. The .CSV files are not inherently the problem, but I've seen many inconsistencies while working with the files. Some include: - Extra field columns showing up at the end of the file. - Question marks "?" appearing in the data. - The inconsistent use of words versus value codes. (i.e. oz and mm versus 0 and 1, etc.) - Errors in the data cause Rocksim to crash. (Stronger field validation could correct.) Not complaining here. All these can be cleaned up and corrected manually. It's just my programming background showing through. I think the Rocksim program is a fantastic piece of software. I wouldn't be spending so much time in the data files if I didn't think so. However correcting some of these minor issues could make a great program even better! ![]() ... Bill |

You're going to tackle the Estes Classic transitions, too, right? Quote:
I noticed those extra fields, too, but left them in place for this set, since the master file had them and it did not seem to be causing trouble. Yet, anyway. As for the words vs numerical values, it's probably a holdover from the earlier versions. I don't think these data files have changed that much over releases, other than adding new items. As for those "?" in the data, are you seeing these in Notepad? In Calc, I see "xxx" whenever the column width is too small to show the data. If I resize the column, the data comes back up. Quote:
I understand. And I agree. RockSim has a lot of potential and could be a very strong program with just a little clean-up. I do know this -- Apogee wants RS to be a teaser for the high-end program, RockSim Pro. I'll bet the code is much the same, though, just with some additional code hooks. One thing I wish RockSim had was a way for third-party code to be hooked in, with published API points. Anyway, I'll tackle the tailcones. It won't take too long, maybe by tomorrow night. I'll combine your file with mine to complete the collection and post it as a single CSV.

![]() Here is the DRAFT parts file for the Semroc balsa reducers (transitions.) It includes all transitions currently available on Semroc's web site except:
- BR-1120NT It also contains "reversed" parts which are designated with a [R] after the part number. This allows you to easily add "small to large" and "large to small" transitions without the need to re-input data values. Have to give Craig credit for this cool time saver! ![]() For CG location I used the same 71% of length used for nosecones for the standard transitions and to 29% of length for the "reversed" transitions. This can be changed based on any thoughts / feedback provided. This file should be considered DRAFT for review purposes only until it can be validated and combined with the tail cone parts that Craig is working on. Thanks, ... Bill |

![]() SLS Magnum-D Hornet
Based on 5341 Centuri Magnum-D Hornet available from 1980-1983. Uses BTH-70 tubing and a BNC-70HAC nose cone are the same as used with the Semroc SLS ARCAS with a 29mm mount and EM-9115 for 24mm flights. Basswood fins, ejection baffle with elastic cord and other Semroc SLS kit standards that make for a strong and reliable rocket. Length: 33.410" Diameter: 2.247" (BTH-70) Span Dia: 9.887" Weight: 10.072 oz D12-3.........305'.........Dv 11 FPS.........72" rod & calm conditions or Not Recommended E9-4...........597'.........Dv 21 FPS.........Not Recommended (Don't even think about it) F24-7.......1,364'.........Dv 10 FPS.........48" x 3/16" rod Best suited for RMS or EconoJets. Try the RoadRunner single use E, F and G motors in your simulations. Not a good candidate for Estes D and E flights. Probably a good design to consider three motor clusters ..... Thanks for looking! ![]()

Thanks Mark ..... It proved to be a really simple but enjoyable build and it gets a lot of attention at the flying field. I fly it with my PerfectFlite Alt15K in the payload section and the black plastic rivets in the photo links are to secure the nose cone. ![]()

Steve - another great looking SLS upscale design! I like how you incorporated the engine baffle into the design. Keep 'em coming! ... Bill |

You guys are getting kind of sophisticated for me. ![]() Can you explain (in layman's terms) what the thinking is behind specifying the CG locations in these balsa parts? ('Cause frankly I'm pretty clueless as to why you're doing that. ![]() Cheers,
