Model rocket motor classification

Model rocket motors are classified based on a variety of criteria, including their size, power, and performance characteristics. The most common classification used for model rocket motors is based on the "letter-number" designation system, which categorizes them by their total impulse (the total amount of thrust produced) and their burn time. ### Key Classifications: 1. **Class Letter**: Indicates the total impulse range of the motor, measured in Newton-seconds (Ns).
