We are happy to announce the release of the newest update to RockSim - the leader in model rocket design and simulation software. This update takes the software from version 10.0 to 10.1, and includes significant revisions to the software to make it more stable and to allow you to design rockets faster than ever.

If you own RockSim version 10 or version 9, there is no charge for this update. We encourage you to download it when you have time. To get the download, visit: https://www.apogeerockets.com/RockSim-v10-1-Update-Process

We are doing a special RockSim FaceBook Live tutorial today at 10 a.m. (12-noon Eastern Time) to show off the new features of the software, and how it allows you to be more creative and efficient. If you missed the live event, it will be archived for you to watch later on both our Facebook page, and on the Apogee Components YouTube Channel.
