I've had more of my issues with images on the fins than with the rest of the design, but yes, the fins will accept image overlays. You apply them through the TEXTURE tab, which is the last tab on the right (after the COLOR tab). You just have to play with the image to see how it "attaches" to the surface. Note - it doesn't always attach itself the way it is supposed to, in spite of what the help files tell you...

I tried a roll pattern on one design. It'd be nice if there was a template that told you how big the image files needed to be to correctly wrap around a given size tube! I can't get it to be positioned at the nose end without the tube turning all black. I'm thinking that I need to make my image file centered on a larger field of 'whiteness' so that when it gets textured on the model, the extra white area will still be there to wrap around the rest of the model. I tried sleeving the portion I wanted the image to cover, but it didn't work out very well. Another rocksim quirk? Last edited by Chris_Timm : 04-25-2006 at 11:14 PM. |

Gooney SCUD-B
Another playoff game, another gooney design.
This time its the SCUD-B! I created a rocksim-world facsimile SCUD cone out of hollow plastic transitions pieced together with zero length shoulders. The fins are proportioned for a gooney look, but the fin shape doesn't scream out anything in particular without adding the distinctive SCUD cone to it. Another design method (i.e. Excelsior) would have been to use the stocl Baby Bertha fins with a SCUD cone and detail the model with panels, rivets and other stuff. Rocksim went nuts with "calculated mass" and the thing came in at close to a POUND! Once I turned it off and set the cone to almost zero mass, things simmed a bit better. Quirky program. |

Nice design Chris, mass problems with SCUD are that the transitions are solid and not hollow. Rocsim 8 does alot of this automatic choosing for you, so watch every detail like a hawk. Hope this helps, JP

Chris, Take a look at my revision. I think this is more what you had in mind. Always remember, using paper transitions also requires an internal structure to hold it all together with. Keep the thickness of paper to about 0.002, and it will be close enough to compute the weight. Centering rings and a tube make for a great internal frame. Another thing to keep in mind, the database for Estes plastic nose cones is corrupt and inaccurate. It lists them as being made of "G10 Fiberglass" instead of "Polystyrene PS", and it has the thickness as 0.125". WAY TOO THICK and WAY TOO HEAVY. You have to manually make these changes to the database and save them in your copy of RocSim. New specs: Just under 2.75 oz with the C6-5 loaded; 1.92 oz empty... The rocket will reach flight V in 36" for all four motors I simmed with. The A8-3 has the highest Dv at 20 FPS... See attached files...

With each new version, I find myself thrilled at the design capability improvements. With each new version, I find myself less than thrilled with the lack of accurate pre-installed stock parts databases. Sure the HPR people have to take the time to individually weigh their glassed components and sim for their exotic construction techniques. I shouldn't have to check each and every mouse-click when designing simple A thru G models. The stock parts database for the several major manufacterers should be included as part of the installation and not an add-on after the fact that must be imported. This version makes is the fourth upgrade for me. The thrill is close to being gone. |

I went back thru and made the cones transitions hollow plastic with a thickness of .05". That really made a difference. Way overstable as it appears. |
