When you take a look on the Apogee website at any particular rocket kit, you see a long list of compatible motors. It can be daunting to figure out which one to choose for your first flight. This week, we go through those motor lists. We explain the important variables listed on the charts and what you can take from them to make an educated decision on which motor would be the "optimum" for your rocket and goals. We'll go through how to make an easy choice, and what factors should go into your decision making for those more complicated projects. This same information can now be used for selecting a motor based on the long list of motors that RockSim v10 says would be appropriate for your own rocketry designs.
