i would recommend using feathers, if you only have 2, put them directly across from each other, if you have 3 feathers put 2 feathers on the same way as if you had 2 and 1 in in the middle of them on 1 side. make sure that when shooting the arrows the feathers don't touch the bow because they will break off or slow down the arrow.
The fins at the base of the rocket help it to fly straight.
Yes because if the cone is not straight it will make the rocket go offside; wonky, and you would not fly straight. It is also harder to control
Add guide fins to the body of the rocket.

4, Why? More stabilization, helps it fly straight up.
by water being placed into the bottle and then, when you launch your rocket, the rocket will spin (if it has at least 2 fins) and the water will spurt out and make the rocket go higher in the air. (Tip:the more it spins,the higher it will fly)
alkaselser and water
vinegar
Get a huge bottle of soft drink (Cokes good), place mentos inside and shake bottle. leave the lid on loosely. Place a rocket on top, then, watch it fly!!
you need to put power-ups in the rocket to make it fly
The rocket never flies.
because if the length of the fuselage is increased then the rocket will become heavier and that will make it fly less distance.
