I like to put them on the lowest section, i feel this gives more stability.
You use fins and a nose cone on a bottle rocket because the cone reduces the drag on the rocket, and the fins help stabilize the rocket.
Duct tape can be used on a bottle rocket to secure components or prevent leaks in the rocket body. It is a strong and versatile adhesive that can help improve the overall performance and safety of the bottle rocket.
Rocket oil
Yes if you use compressed air inside the rocket. Or you can use agitated methanol and a flame for thrust like a whoosh rocket.
It is not recommended to use another type of liquid for a bottle rocket besides water. Water is the safest and most commonly used liquid for bottle rockets as it provides the necessary weight and propulsion for the rocket to launch. Using other liquids could be dangerous or ineffective.

Helicopters don't use fixed wings
A rocket is a form of propulsion. If a rocket is used to power an airplane, it is referred to as a rocket-plane, and has wings like an airplane. It the rocket is use to propel a vehicle vertically, which does not need wicgs to provide lift, it is called simply a rocket. Sometimes fins are used to stabilize or guide a rocket in flight, but these are referred to as fins rather than wings.
You need 17 bottles. Thank you for your cooperation.
This depends on many things, it varies with the agle you are goint to shoot it with and the funktion of the rocket (length, stability, perhaps returning to the shooter) Assuming your rocket is to be launched straight up in the air the wings is only a mean of stabilizing it. For this kind of rocket the wings should be hard and has as little resistance as possible The shape should be like the triangular ones you see in the movies and you should use about 3 or 4 of them hope this helps:)
The mass of a rocket bottle will depend on various factors such as the volume of the bottle, desired thrust, and flight characteristics. Typically, a rocket bottle should be lightweight to maximize thrust-to-weight ratio, but also sturdy enough to withstand the pressure during launch and flight. It's best to consult with a rocketry expert or use simulation software to determine the optimal mass for your specific rocket design.
