How Does the Number of Fins Affect the Speed of a Paper Rocket?

[GreatEscapist]

In my physics class, we are reviewing trajectory, so we are setting up a lab where we shoot some form of a paper rocket across our gym with an air compressor, and hopefully hit a target. The paper is kinda thick, but we can add whatever we want onto it, if we make it think it will make it will go faster. The object is to make it go faster, not higher, so that you have a more accurate chance of hitting the target.
Okay. Now here's my question:
Is it faster to have two fins on the rocket, opposite each other, or is it faster to put on four?

The answer to this question depends on a few factors, such as the size and shape of your rocket, the power of your air compressor, and the type of paper you are using. Generally speaking, having two fins opposite each other will provide more stability and control, while having four fins will provide more lift and thrust. Ultimately, the best option is to experiment with both configurations and see which one works better for your particular setup.
