Here's the Estes Optima (2035)... I've created sims for the stock color schemes, my 29mm redshifted clone, and a dual deploy version that I'd like to build some day. The fin decals on this (the yellow) version do not match the instructions' arrangement, but you can do that on your own if you want (looks odd to me). Here's the blue/grey version and what I'd do instead (black and white): As well as the version with the black nosecone/forward airframe... As I guess was intended from the instructions: And what I'd do instead (less masking involved (thus easier painting)): The 29mm clones have nearly identical appearances to the stock models. However, I've eliminated the launch lug, and gone with rail buttons. These sims are what I was able to accomplish with the current version of OR. I understand in the future, rail button support will be added. So, I'll be updating these again at some time. In the updated versions the "fin decals" which were simulated with fins, have been replaced with "decals" and thus the old versions are obsolete, and should be discarded. Each of the previous versions of the files were downloaded an average of 120 times.
