The thrust of my rocket was provided by the propellant in the engine and the hot gases that came out. The stability of the rocket affected the flight because of the fins. If the fins weren't stable, then the rocket would have more drag and would go as high as fast. Another factor that affected the flight of the rocket was the weight of the rocket. Looking at the results, since this rocket doesn't have much lift like an airplane does, the weight of the rocket affects the flight a lot. The lighter the rocket, the amount of time it took to get to the maximum was usually longer.
