JPVegh,
Do you have "official" files for the Estes E12 motors? I could get them added to the next OpenRocket release.

There are two main ways to work with the motor database in OpenRocket.
#1 the easy way.
#2 The perfectionist way.
The easy method is just that - easy.
The perfectionist method is more difficult, but affords much greater control.
To start you should know that OpenRocket has a Built-in motor Database. In addition to the "Built-in" motors, you can tell OpenRocket to use your own collection of motor files.
The easy way.
You can find motor or engine files around the interwebs at places like thrustcurve.org
Motor files are simply files that contain motor data. The file names end in .eng or .rse.
For example, you can surf to thrust curve and search for a particular motor - for example the G138.
Then you can download the motor file to your computer.
It looks like this AeroTech_G138.eng
The trick is - to keep all your motor files in one folder on your computer. I keep all my motor files in a folder called "all my motor files".
This can be any folder anywhere on your computer, as long as you know where it is and can find it.
I got a nice big collection of them that I have gathered over the years.
Now Run OpenRocket.
Click on EDIT
Then Click PREFERENCES
Then Click OPTIONS
Where it says "User defined thrust curves:"
Click the ADD button
Then browse to your collection and click the ADD button.
Open rocket will use the built-in motor database AND the files in your motor folder.
All done - it's just that easy.
