The fins on a rocket are just there to create stability. As long as there are enough to provide a restoring force against a disturbance, it shouldn't matter. But ...Enough means at least three, symetrically placed, with enough area so that when the rocket tips off of its path a little bit the fins provide aerodynamic force to put it straight again. If you only had two, a disturbance in the plane of the fins would not get corrected and the rocket would veer off course. With three, any tipping off of the flight path hits at least one of the fins in a way to correct the misalignment. Four works, too. Any more than that and you're just adding drag, which will shorten the flight.Note well that the key parameter is the area of the fin times the distance it's lift center is behind the mass center of the rocket. That's why something with the fins behind the engine nozzle works so well, because the lift center is behind the entire rocket. Before I knew that rule I built a seriously overpowered rocket with gigantic fins that came all the way up to the nose. Instead of flying with great stability as I expected, it jumped off the launch rod and headed for launch control, then writhed on the ground like a beached whale until the parachute charge went off.

How do fins on a straw rocket affect it's flight?
Fins on a rocket affects its flight by the way they are built on the rocket
How does streamlining affect the flight of a rocket?
Incredibly ! -In rocket flight streamlining is the single most important factor.
How does the chute wadding on a model rocket affect its flight?
it helps protect its cover
Do Flight-paths affect home value?
TwoIts not going to affect your home value much.they affect the stability of th rocket flightAntarctica is not on any commercial flight paths
How Does adding weight to a rocket affect its flight process?
Weight is a killer in terms of altitude.
Does the length of your rocket affect the flight of your rocket?
Indeed they do! There are a few primary forces that affect a rocket's flight, and one of those forces is drag. Aerodynamics is basically how drag affects an object in motion, and making something "more aerodynamic" means building it in such a way that it has less drag. The less drag something experiences, the faster (and in the case of model rockets, higher) it can go.
How does a nose cone on a bottle rocket affect its flight path?
While a nose cone can either reduce or add drag, it provides a minimal amount of stability to the rocket' flight path. The fins are the most critical component for stabilizing a rocket's flight path; that's where your focus should be.
How does the size affect the flight of a rocket?
A small rocket might go higher because a smaller rocket has less weight
Does the aerodynamics affect the flight of a rocket?
Of course. Your construction and fin alignment must be as near perfect as you can make it.
Why did people start making two stage rockets?
One of the key factors in rocketry is the weight of the rocket. By designing a rocket that ejects parts of the rocket that has emptied it's fuel tanks decreases the overall weght of the rocket, extending the flight of the rocket.
What is the difference between rocket flight and airplane flight?
A plane needs air, a rocket doesn't.
What are the most important parts of a rocket?
The most important parts of a rocket are the payload (what the rocket is carrying), the propulsion system (engines and fuel), the guidance system (to control the rocket's flight path), and the structural components (body, fins, and nose cone) that hold everything together and provide stability.
