This is your outbox, but right now it's empty.
To find files, search for motors you want to use, then pick one of the available Simulator Files and click "Add this file to my outbox."
For convenience, this site can also provide sets of motor files for in-production motors by manufacturer. Note that when there is more than one entry for a motor, the most recent one is used. Also some motors may not have any data files uploaded for one or both formats.
|Animal Motor Works||AMW.eng||AMW.rse|
|Kosdon by AeroTech||KBA.eng||KBA.rse|
|Southern Cross Rocketry||SCR.eng||SCR.rse|
If a motor you want to use is missing from the set you downloaded, consider creating a file for that motor and uploading it. See Contribute Data for how you can do that. These sets are produced on demand so they always contain the latest data available.
