Recalculating the center of gravity (CG) based on the new motor and payload is essential because changing to a heavier motor can significantly affect the overall balance of the rocket. The center of gravity is crucial for stable flight; if it shifts too far forward or backward, it can lead to unstable flight characteristics or even crashes.

When you change the motor to a heavier one, the mass distribution of the rocket changes, which can alter the CG position. By recalculating the CG, you ensure that the rocket remains aerodynamically stable. A correctly calculated CG will help in maintaining proper flight dynamics and recovery performance, making it vital to verify after any significant changes in the rocket's configuration, such as changing the motor weight.

Other options may be important in the overall safety inspection process but do not directly address the crucial need to ensure CG is correctly calculated after a weight change, as stability is a foundation for safety in rocketry.
