    ThrustCurve.org API coming back

    I have made progress on the API. The "compatible" and new-style endpoints for metadata, search and download are working. This should enable RockSim and OpenRocket to download data again. If anyone else has programs that query and download data from ThrustCurve.org, they should be working as...

    Ring Tail Issues in RockSim

    I picked up a couple of parts from a free parts bin at my local launch, and want to build a ring tail rocket with them. My current plan has a 4 inch body tube and a 5 inch ring tail that is 1 inch long. However, I am dubious of RockSim's accuracy on the matter. Adding a ring tail to the rocket...

    Rocksim question

    Attached is a photo of my Rocksim window when I open the file for the Mach1 BT55 Scat that I downloaded from the site. Does anyone know what the (CG: nan In) means?

    OpenRocket not recognizing intermediate stage after export from RockSim.

    Hi everyone! Long-time lurker, first-time poster. I'm intentionally reposting this here and deleting the old thread, because on reflection it doesn't quite fit in "Rocketry Electronics and Software." No replies over there to miss, either. I'm exploring high-altitude darts, and conversations...

    OpenRocket not recognizing intermediate stage after export from RockSim.

    Hi everyone! Long-time lurker, first-time poster. I'm exploring high-altitude darts, and conversations with a friend of mine with a large amount of HPR experience has led to some design exchanges. Unfortunately, we both use different sim software - he uses RockSim, and I use OpenRocket. This...

    Rocksim - is it possible to scale a rocket (and all the parts) in Rocksim?

    I would like to increase the size of a model I have created in Rocksim by 25%. Is there a scaling tool where I can scale the whole rocket without having to remodel every part? I would then go in a adjust as needed. Thanks Ben
