When there are no models in the database you will see the screen to the right. To add a model, click the green plus sign.













Clicking the green plus sign from the previous screen will bring up the screen to the right. This screen allows you to add a new rocket to the program. You can change the icon to a picture of your rocket. Click the icon that is displayed and your gallery program will come up and allow you to choose a different picture. Fill in the name, manufacturer, mass, diameter, and drag coefficient and then press 'OK' for your rocket to be added. The units displayed here can be changed in the Settings Menu.












The screen at right shows an example rocket being added. 













Once you have added your model it will now show up on the Model screen.














On the model screen, if you click on a model, that models information screen will appear (shown below). However, if you long-press on a model the dialog to left will appear. This dialog allows you to modify an existing model, show the model, duplicate the model, or delete the model.













If you select a model from the Models screen, it's information screen will appear. From this screen you can simulate the models trajectory. To do so, select the green plus button next to "Configuration". This will bring up the list of motors to choose from.













Motor List

From the motor list, choose the motor that you want to simulate in the rocket. Once a motor is selected the program will automatically simulate the flight. This may take several seconds and once complete, you will be taken back to the rocket information page.












This is what the rocket information page might look like after performing a couple of simulations. If you want to delete one of the simulation runs you can long press on one of the configurations and the program will ask you if you want to delete it.















 Simulation Results

Selecting one of the simulation configurations from the model information page will take you to the simulation results. This first page shows the expected velocity for the standard delay times of the motor that was simulated.
